This can be used to clean up any 3rd party bindings to the DOM + * element before it is removed. + * + * ### Methods + * - `controller(name)` - retrieves the controller of the current element or its parent. By default + * retrieves controller associated with the `ngController` directive. If `name` is provided as + * camelCase directive name, then the controller for this directive will be retrieved (e.g. + * `'ngModel'`). + * - `injector()` - retrieves the injector of the current element or its parent. + * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current + * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to + * be enabled. + * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the + * current element. This getter should be used only on elements that contain a directive which starts a new isolate + * scope. Calling `scope()` on this element always returns the original non-isolate scope. + * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. + * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top + * parent element is reached. + * + * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x.

This is a good place to put initialization code for your controller. + * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The + * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an + * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a + * component such as cloning the bound value to prevent accidental mutation of the outer value. + * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on + * changes. Any actions that you wish to take in response to the changes that you detect must be + * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook + * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not + * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; + * if detecting changes, you must store the previous value(s) for comparison to the current values. + * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing + * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in + * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent + * components will have their `$onDestroy()` hook called before child components. + * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link + * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. + * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since + * they are waiting for their template to load asynchronously and their own compilation and linking has been + * suspended until that occurs. + * + * #### Comparison with Angular 2 life-cycle hooks + * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are + * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2: + * + * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`. + * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor. + * In Angular 2 you can only define hooks on the prototype of the Component class. + * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to + * `ngDoCheck` in Angular 2 + * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be + * propagated throughout the application. + * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an + * error or do nothing depending upon the state of `enableProdMode()`. + * + * #### Life-cycle hook examples + * + * This example shows how you can check for mutations to a Date object even though the identity of the object + * has not changed. + * + * <example name="doCheckDateExample" module="do-check-module"> + * <file name="app.js"> + * angular.module('do-check-module', []) + * .component('app', { + * template: + * 'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' + + * 'Date: {{ $ctrl.date }}' + + * '<test date="$ctrl.date"></test>', + * controller: function() { + * this.date = new Date(); + * this.month = this.date.getMonth(); + * this.updateDate = function() { + * this.date.setMonth(this.month); + * }; + * } + * }) + * .component('test', { + * bindings: { date: '<' }, + * template: + * '<pre>{{ $ctrl.log | json }}</pre>', + * controller: function() { + * var previousValue; + * this.log = []; + * this.$doCheck = function() { + * var currentValue = this.date && this.date.valueOf(); + * if (previousValue !== currentValue) { + * this.log.push('doCheck: date mutated: ' + this.date); + * previousValue = currentValue; + * } + * }; + * } + * }); + * </file> + * <file name="index.html"> + * <app></app> + * </file> + * </example> + * + * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the + * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large + * arrays or objects can have a negative impact on your application performance) + * + * <example name="doCheckArrayExample" module="do-check-module"> + * <file name="index.html"> + * <div ng-init="items = []"> + * <button ng-click="items.push(items.length)">Add Item</button> + * <button ng-click="items = []">Reset Items</button> + * <pre>{{ items }}</pre> + * <test items="items"></test> + * </div> + * </file> + * <file name="app.js"> + * angular.module('do-check-module', []) + * .component('test', { + * bindings: { items: '<' }, + * template: + * '<pre>{{ $ctrl.log | json }}</pre>', + * controller: function() { + * this.log = []; + * + * this.$doCheck = function() { + * if (this.items_ref !== this.items) { + * this.log.push('doCheck: items changed'); + * this.items_ref = this.items; + * } + * if (!angular.equals(this.items_clone, this.items)) { + * this.log.push('doCheck: items mutated'); + * this.items_clone = angular.copy(this.items); + * } + * }; + * } + * }); + * </file> + * </example> + * + * + * ### Directive Definition Object + * + * The directive definition object provides instructions to the {@link ng.$compile + * compiler}. The attributes are: + * + * #### `multiElement` + * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between + * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them + * together as the directive elements. It is recommended that this feature be used on directives + * which are not strictly behavioral (such as {@link ngClick}), and which + * do not manipulate or replace child nodes (such as {@link ngInclude}). + * + * #### `priority` + * When there are multiple directives defined on a single DOM element, sometimes it + * is necessary to specify the order in which the directives are applied. The `priority` is used + * to sort the directives before their `compile` functions get called. Priority is defined as a + * number. Directives with greater numerical `priority` are compiled first. Pre-link functions + * are also run in priority order, but post-link functions are run in reverse order. The order + * of directives with the same priority is undefined. The default priority is `0`. + * + * #### `terminal` + * If set to true then the current `priority` will be the last set of directives + * which will execute (any directives at the current priority will still execute + * as the order of execution on same `priority` is undefined). Note that expressions + * and other directives used in the directive's template will also be excluded from execution. + * + * #### `scope` + * The scope property can be `false`, `true`, or an object: + * + * * **`false` (default):** No scope will be created for the directive. The directive will use its + * parent's scope. + * + * * **`true`:** A new child scope that prototypically inherits from its parent will be created for + * the directive's element. If multiple directives on the same element request a new scope, + * only one new scope is created. + * + * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The + * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent + * scope. This is useful when creating reusable components, which should not accidentally read or modify + * data in the parent scope. + * + * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the + * directive's element. These local properties are useful for aliasing values for templates. The keys in + * the object hash map to the name of the property on the isolate scope; the values define how the property + * is bound to the parent scope, via matching attributes on the directive's element: + * + * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is + * always a string since DOM attributes are strings. If no `attr` name is specified then the + * attribute name is assumed to be the same as the local name. Given `<my-component + * my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`, + * the directive's scope property `localName` will reflect the interpolated value of `hello + * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's + * scope. The `name` is read from the parent scope (not the directive's scope). + * + * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression + * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. + * If no `attr` name is specified then the attribute name is assumed to be the same as the local + * name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: { + * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the + * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in + * `localModel` and vice versa. Optional attributes should be marked as such with a question mark: + * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't + * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`}) + * will be thrown upon discovering changes to the local value, since it will be impossible to sync + * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`} + * method is used for tracking changes, and the equality check is based on object identity. + * However, if an object literal or an array literal is passed as the binding expression, the + * equality check is done by value (using the {@link angular.equals} function). It's also possible + * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection + * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional). + * + * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an + * expression passed via the attribute `attr`. The expression is evaluated in the context of the + * parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the + * local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`. + * + * For example, given `<my-component my-attr="parentModel">` and directive definition of + * `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the + * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected + * in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however + * two caveats: + * 1. one-way binding does not copy the value from the parent to the isolate scope, it simply + * sets the same value. That means if your bound value is an object, changes to its properties + * in the isolated scope will be reflected in the parent scope (because both reference the same object). + * 2. one-way binding watches changes to the **identity** of the parent value. That means the + * {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference + * to the value has changed. In most cases, this should not be of concern, but can be important + * to know if you one-way bind to an object, and then replace that object in the isolated scope. + * If you now change a property of the object in your parent scope, the change will not be + * propagated to the isolated scope, because the identity of the object on the parent scope + * has not changed. Instead you must assign a new object. + * + * One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings + * back to the parent. However, it does not make this completely impossible. + * + * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If + * no `attr` name is specified then the attribute name is assumed to be the same as the local name. + * Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: { + * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for + * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope + * via an expression to the parent scope. This can be done by passing a map of local variable names + * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` + * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. + * + * In general it's possible to apply more than one directive to one element, but there might be limitations + * depending on the type of scope required by the directives. The following points will help explain these limitations. + * For simplicity only two directives are taken into account, but it is also applicable for several directives: + * + * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope + * * **child scope** + **no scope** => Both directives will share one single child scope + * * **child scope** + **child scope** => Both directives will share one single child scope + * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use + * its parent's scope + * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot + * be applied to the same element. + * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives + * cannot be applied to the same element. + * + * + * #### `bindToController` + * This property is used to bind scope properties directly to the controller. It can be either + * `true` or an object hash with the same format as the `scope` property. + * + * When an isolate scope is used for a directive (see above), `bindToController: true` will + * allow a component to have its properties bound to the controller, rather than to scope. + * + * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller + * properties. You can access these bindings once they have been initialized by providing a controller method called + * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings + * initialized. + * + * <div class="alert alert-warning"> + * **Deprecation warning:** although bindings for non-ES6 class controllers are currently + * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization + * code that relies upon bindings inside a `$onInit` method on the controller, instead. + * </div> + * + * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. + * This will set up the scope bindings to the controller directly. Note that `scope` can still be used + * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate + * scope (useful for component directives). + * + * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. + * + * + * #### `controller` + * Controller constructor function. The controller is instantiated before the + * pre-linking phase and can be accessed by other directives (see + * `require` attribute). This allows the directives to communicate with each other and augment + * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: + * + * * `$scope` - Current scope associated with the element + * * `$element` - Current element + * * `$attrs` - Current attributes object for the element + * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: + * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: + * * `scope`: (optional) override the scope. + * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. + * * `futureParentElement` (optional): + * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. + * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkingFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like `<svg>`). + * * See also the `directive.templateNamespace` property. + * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) + * then the default transclusion is provided. + * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns + * `true` if the specified slot contains content (i.e. one or more DOM nodes). + * + * #### `require` + * Require another directive and inject its controller as the fourth argument to the linking function. The + * `require` property can be a string, an array or an object: + * * a **string** containing the name of the directive to pass to the linking function + * * an **array** containing the names of directives to pass to the linking function. The argument passed to the + * linking function will be an array of controllers in the same order as the names in the `require` property + * * an **object** whose property values are the names of the directives to pass to the linking function. The argument + * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding + * controllers. + * + * If the `require` property is an object and `bindToController` is truthy, then the required controllers are + * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers + * have been constructed but before `$onInit` is called. + * If the name of the required controller is the same as the local name (the key), the name can be + * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. + * See the {@link $compileProvider#component} helper for an example of how this can be used. + * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is + * raised (unless no link function is specified and the required controllers are not being bound to the directive + * controller, in which case error checking is skipped). The name can be prefixed with: + * + * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. + * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. + * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. + * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. + * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass + * `null` to the `link` fn if not found. + * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass + * `null` to the `link` fn if not found. + * + * + * #### `controllerAs` + * Identifier name for a reference to the controller in the directive's scope. + * This allows the controller to be referenced from the directive template. This is especially + * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible + * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the + * `controllerAs` reference might overwrite a property that already exists on the parent scope. + * + * + * #### `restrict` + * String of subset of `EACM` which restricts the directive to a specific directive + * declaration style. If omitted, the defaults (elements and attributes) are used. + * + * * `E` - Element name (default): `<my-directive></my-directive>` + * * `A` - Attribute (default): `<div my-directive="exp"></div>` + * * `C` - Class: `<div class="my-directive: exp;"></div>` + * * `M` - Comment: `<!-- directive: my-directive exp -->` + * + * + * #### `templateNamespace` + * String representing the document type used by the markup in the template. + * AngularJS needs this information as those elements need to be created and cloned + * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`. + * + * * `html` - All root nodes in the template are HTML. Root nodes may also be + * top-level elements such as `<svg>` or `<math>`. + * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`). + * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`). + * + * If no `templateNamespace` is specified, then the namespace is considered to be `html`. + * + * #### `template` + * HTML markup that may: + * * Replace the contents of the directive's element (default). + * * Replace the directive's element itself (if `replace` is true - DEPRECATED). + * * Wrap the contents of the directive's element (if `transclude` is true). + * + * Value may be: + * + * * A string. For example `<div red-on-hover>{{delete_str}}</div>`. + * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` + * function api below) and returns a string value. + * + * + * #### `templateUrl` + * This is similar to `template` but the template is loaded from the specified URL, asynchronously. + * + * Because template loading is asynchronous the compiler will suspend compilation of directives on that element + * for later when the template has been resolved. In the meantime it will continue to compile and link + * sibling and parent elements as though this element had not contained any directives. + * + * The compiler does not suspend the entire compilation to wait for templates to be loaded because this + * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the + * case when only one deeply nested directive has `templateUrl`. + * + * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} + * + * You can specify `templateUrl` as a string representing the URL or as a function which takes two + * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns + * a string value representing the url. In either case, the template URL is passed through {@link + * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. + * + * + * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0) + * specify what the template should replace. Defaults to `false`. + * + * * `true` - the template will replace the directive's element. + * * `false` - the template will replace the contents of the directive's element. + * + * The replacement process migrates all of the attributes / classes from the old element to the new + * one. See the {@link guide/directive#template-expanding-directive + * Directives Guide} for an example. + * + * There are very few scenarios where element replacement is required for the application function, + * the main one being reusable custom components that are used within SVG contexts + * (because SVG doesn't work with custom elements in the DOM tree). + * + * #### `transclude` + * Extract the contents of the element where the directive appears and make it available to the directive. + * The contents are compiled and provided to the directive as a **transclusion function**. See the + * {@link $compile#transclusion Transclusion} section below. + * + * + * #### `compile` + * + * ```js + * function compile(tElement, tAttrs, transclude) { ... } + * ``` + * + * The compile function deals with transforming the template DOM. Since most directives do not do + * template transformation, it is not used often. The compile function takes the following arguments: + * + * * `tElement` - template element - The element where the directive has been declared. It is + * safe to do template transformation on the element and child elements only. + * + * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared + * between all directive compile functions. + * + * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` + * + * <div class="alert alert-warning"> + * **Note:** The template instance and the link instance may be different objects if the template has + * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that + * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration + * should be done in a linking function rather than in a compile function. + * </div> + + * <div class="alert alert-warning"> + * **Note:** The compile function cannot handle directives that recursively use themselves in their + * own templates or compile functions. Compiling these directives results in an infinite loop and + * stack overflow errors. + * + * This can be avoided by manually using $compile in the postLink function to imperatively compile + * a directive's template instead of relying on automatic template compilation via `template` or + * `templateUrl` declaration or manual compilation inside the compile function. + * </div> + * + * <div class="alert alert-danger"> + * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it + * e.g. does not know about the right outer scope. Please use the transclude function that is passed + * to the link function instead. + * </div> + + * A compile function can have a return value which can be either a function or an object. + * + * * returning a (post-link) function - is equivalent to registering the linking function via the + * `link` property of the config object when the compile function is empty. + * + * * returning an object with function(s) registered via `pre` and `post` properties - allows you to + * control when a linking function should be called during the linking phase. See info about + * pre-linking and post-linking functions below. + * + * + * #### `link` + * This property is used only if the `compile` property is not defined. + * + * ```js + * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } + * ``` + * + * The link function is responsible for registering DOM listeners as well as updating the DOM. It is + * executed after the template has been cloned. This is where most of the directive logic will be + * put. + * + * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the + * directive for registering {@link ng.$rootScope.Scope#$watch watches}. + * + * * `iElement` - instance element - The element where the directive is to be used. It is safe to + * manipulate the children of the element only in `postLink` function since the children have + * already been linked. + * + * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared + * between all directive linking functions. + * + * * `controller` - the directive's required controller instance(s) - Instances are shared + * among all directives, which allows the directives to use the controllers as a communication + * channel. The exact value depends on the directive's `require` property: + * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one + * * `string`: the controller instance + * * `array`: array of controller instances + * + * If a required controller cannot be found, and it is optional, the instance is `null`, + * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. + * + * Note that you can also require the directive's own controller - it will be made available like + * any other controller. + * + * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. + * This is the same as the `$transclude` parameter of directive controllers, + * see {@link ng.$compile#-controller- the controller section for details}. + * `function([scope], cloneLinkingFn, futureParentElement)`. + * + * #### Pre-linking function + * + * Executed before the child elements are linked. Not safe to do DOM transformation since the + * compiler linking function will fail to locate the correct elements for linking. + * + * #### Post-linking function + * + * Executed after the child elements are linked. + * + * Note that child elements that contain `templateUrl` directives will not have been compiled + * and linked since they are waiting for their template to load asynchronously and their own + * compilation and linking has been suspended until that occurs. + * + * It is safe to do DOM transformation in the post-linking function on elements that are not waiting + * for their async templates to be resolved. + * + * + * ### Transclusion + * + * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and + * copying them to another part of the DOM, while maintaining their connection to the original AngularJS + * scope from where they were taken. + * + * Transclusion is used (often with {@link ngTransclude}) to insert the + * original contents of a directive's element into a specified place in the template of the directive. + * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded + * content has access to the properties on the scope from which it was taken, even if the directive + * has isolated scope. + * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. + * + * This makes it possible for the widget to have private state for its template, while the transcluded + * content has access to its originating scope. + * + * <div class="alert alert-warning"> + * **Note:** When testing an element transclude directive you must not place the directive at the root of the + * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives + * Testing Transclusion Directives}. + * </div> + * + * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the + * directive's element, the entire element or multiple parts of the element contents: + * + * * `true` - transclude the content (i.e. the child nodes) of the directive's element. + * * `'element'` - transclude the whole of the directive's element including any directives on this + * element that defined at a lower priority than this directive. When used, the `template` + * property is ignored. + * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. + * + * **Mult-slot transclusion** is declared by providing an object for the `transclude` property. + * + * This object is a map where the keys are the name of the slot to fill and the value is an element selector + * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) + * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). + * + * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives} + * + * If the element selector is prefixed with a `?` then that slot is optional. + * + * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to + * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. + * + * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements + * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call + * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and + * injectable into the directive's controller. + * + * + * #### Transclusion Functions + * + * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion + * function** to the directive's `link` function and `controller`. This transclusion function is a special + * **linking function** that will return the compiled contents linked to a new transclusion scope. + * + * <div class="alert alert-info"> + * If you are just using {@link ngTransclude} then you don't need to worry about this function, since + * ngTransclude will deal with it for us. + * </div> + * + * If you want to manually control the insertion and removal of the transcluded content in your directive + * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery + * object that contains the compiled DOM, which is linked to the correct transclusion scope. + * + * When you call a transclusion function you can pass in a **clone attach function**. This function accepts + * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded + * content and the `scope` is the newly created transclusion scope, which the clone will be linked to. + * + * <div class="alert alert-info"> + * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function + * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. + * </div> + * + * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone + * attach function**: + * + * ```js + * var transcludedContent, transclusionScope; + * + * $transclude(function(clone, scope) { + * element.append(clone); + * transcludedContent = clone; + * transclusionScope = scope; + * }); + * ``` + * + * Later, if you want to remove the transcluded content from your DOM then you should also destroy the + * associated transclusion scope: + * + * ```js + * transcludedContent.remove(); + * transclusionScope.$destroy(); + * ``` + * + * <div class="alert alert-info"> + * **Best Practice**: if you intend to add and remove transcluded content manually in your directive + * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), + * then you are also responsible for calling `$destroy` on the transclusion scope. + * </div> + * + * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} + * automatically destroy their transcluded clones as necessary so you do not need to worry about this if + * you are simply using {@link ngTransclude} to inject the transclusion into your directive. + * + * + * #### Transclusion Scopes + * + * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion + * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed + * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it + * was taken. + * + * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look + * like this: + * + * ```html + * <div ng-app> + * <div isolate> + * <div transclusion> + * </div> + * </div> + * </div> + * ``` + * + * The `$parent` scope hierarchy will look like this: + * + ``` + - $rootScope + - isolate + - transclusion + ``` + * + * but the scopes will inherit prototypically from different scopes to their `$parent`. + * + ``` + - $rootScope + - transclusion + - isolate + ``` + * + * + * ### Attributes + * + * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the + * `link()` or `compile()` functions. It has a variety of uses. + * + * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways: + * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access + * to the attributes. + * + * * *Directive inter-communication:* All directives share the same instance of the attributes + * object which allows the directives to use the attributes object as inter directive + * communication. + * + * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object + * allowing other directives to read the interpolated value. + * + * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes + * that contain interpolation (e.g. `src="{{bar}}"`).

See also the directive.controller property. + * + * Calling the linking function returns the element of the template. It is either the original + * element passed in, or the clone of the element if the `cloneAttachFn` is provided. + * + * After linking the view is not updated until after a call to $digest which typically is done by + * Angular automatically. + * + * If you need access to the bound view, there are two ways to do it: + * + * - If you are not asking the linking function to clone the template, create the DOM element(s) + * before you send them to the compiler and keep this reference around. + * ```js + * var element = $compile('<p>{{total}}</p>')(scope); + * ``` + * + * - if on the other hand, you need the element to be cloned, the view reference from the original + * example would not point to the clone, but rather to the original template that was cloned. In + * this case, you can access the clone via the cloneAttachFn: + * ```js + * var templateElement = angular.element('<p>{{total}}</p>'), + * scope = ....; + * + * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) { + * //attach the clone to DOM document at the right place + * }); + * + * //now we have reference to the cloned DOM via `clonedElement` + * ``` + * + * + * For information on how the compiler works, see the + * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide. + * + * @knownIssue + * + * ### Double Compilation + * + Double compilation occurs when an already compiled part of the DOM gets + compiled again.

While for simple usage patterns this doesn't matter much, for advanced usage + * it is important to familiarize yourself with these APIs and the guarantees they provide. + * + * + * ## General usage + * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} — + * that is used to generate an HTTP request and returns a {@link ng.$q promise}. + * + * ```js + * // Simple GET request example: + * $http({ + * method: 'GET', + * url: '/someUrl' + * }).then(function successCallback(response) { + * // this callback will be called asynchronously + * // when the response is available + * }, function errorCallback(response) { + * // called asynchronously if an error occurs + * // or server returns response with an error status. + * }); + * ``` + * + * The response object has these properties: + * + * - **data** – `{string|Object}` – The response body transformed with the transform + * functions. + * - **status** – `{number}` – HTTP status code of the response. + * - **headers** – `{function([headerName])}` – Header getter function. + * - **config** – `{Object}` – The configuration object that was used to generate the request. + * - **statusText** – `{string}` – HTTP status text of the response. + * + * A response status code between 200 and 299 is considered a success status and will result in + * the success callback being called. Any response status code outside of that range is + * considered an error status and will result in the error callback being called. + * Also, status codes less than -1 are normalized to zero. -1 usually means the request was + * aborted, e.g. using a `config.timeout`. + * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning + * that the outcome (success or error) will be determined by the final response status code. + * + * + * ## Shortcut methods + * + * Shortcut methods are also available. All shortcut methods require passing in the URL, and + * request data must be passed in for POST/PUT requests. An optional config can be passed as the + * last argument. + * + * ```js + * $http.get('/someUrl', config).then(successCallback, errorCallback); + * $http.post('/someUrl', data, config).then(successCallback, errorCallback); + * ``` + * + * Complete list of shortcut methods: + * + * - {@link ng.$http#get $http.get} + * - {@link ng.$http#head $http.head} + * - {@link ng.$http#post $http.post} + * - {@link ng.$http#put $http.put} + * - {@link ng.$http#delete $http.delete} + * - {@link ng.$http#jsonp $http.jsonp} + * - {@link ng.$http#patch $http.patch} + * + * + * ## Writing Unit Tests that use $http + * When unit testing (using {@link ngMock ngMock}), it is necessary to call + * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending + * request using trained responses. + * + * ``` + * $httpBackend.expectGET(...); + * $http.get(...); + * $httpBackend.flush(); + * ``` + * + * ## Deprecation Notice + * <div class="alert alert-danger"> + * The `$http` legacy promise methods `success` and `error` have been deprecated and will be + * removed in v1.6.0. + * Use the standard `then` method instead. + * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to + * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error. + * </div> + * + * ## Setting HTTP Headers + * + * The $http service will automatically add certain HTTP headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - <code>Accept: application/json, text/plain, \*/\*</code> + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from these configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with the lowercased HTTP method name as the key, e.g. + * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. + * + * The defaults can also be set at runtime via the `$http.defaults` object in the same + * fashion. For example: + * + * ``` + * module.run(function($http) { + * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; + * }); + * ``` + * + * In addition, you can supply a `headers` property in the config object passed when + * calling `$http(config)`, which overrides the defaults without changing them globally. + * + * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, + * Use the `headers` property, setting the desired header to `undefined`. For example: + * + * ```js + * var req = { + * method: 'POST', + * url: 'http://example.com', + * headers: { + * 'Content-Type': undefined + * }, + * data: { test: 'test' } + * } + * + * $http(req).then(function(){...}, function(){...}); + * ``` + * + * ## Transforming Requests and Responses + * + * Both requests and responses can be transformed using transformation functions: `transformRequest` + * and `transformResponse`. These properties can be a single function that returns + * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, + * which allows you to `push` or `unshift` a new transformation function into the transformation chain. + * + * <div class="alert alert-warning"> + * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. + * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). + * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest + * function will be reflected on the scope and in any templates where the object is data-bound. + * To prevent this, transform functions should have no side-effects. + * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. + * </div> + * + * ### Default Transformations + * + * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and + * `defaults.transformResponse` properties. If a request does not provide its own transformations + * then these will be applied. + * + * You can augment or replace the default transformations by modifying these properties by adding to or + * replacing the array. + * + * Angular provides the following default transformations: + * + * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`): + * + * - If the `data` property of the request configuration object contains an object, serialize it + * into JSON format. + * + * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`): + * + * - If XSRF prefix is detected, strip it (see Security Considerations section below). + * - If JSON response is detected, deserialize it using a JSON parser. + * + * + * ### Overriding the Default Transformations Per Request + * + * If you wish to override the request/response transformations only for a single request then provide + * `transformRequest` and/or `transformResponse` properties on the configuration object passed + * into `$http`. + * + * Note that if you provide these properties on the config object the default transformations will be + * overwritten. If you wish to augment the default transformations then you must include them in your + * local transformation array. + * + * The following code demonstrates adding a new response transformation to be run after the default response + * transformations have been run. + * + * ```js + * function appendTransform(defaults, transform) { + * + * // We can't guarantee that the default transformation is an array + * defaults = angular.isArray(defaults) ? defaults : [defaults]; + * + * // Append the new transformation to the defaults + * return defaults.concat(transform); + * } + * + * $http({ + * url: '...', + * method: 'GET', + * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { + * return doTransform(value); + * }) + * }); + * ``` + * + * + * ## Caching + * + * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must + * set the config.cache value or the default cache value to TRUE or to a cache object (created + * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes + * precedence over the default cache value. + * + * In order to: + * * cache all responses - set the default cache value to TRUE or to a cache object + * * cache a specific response - set config.cache value to TRUE or to a cache object + * + * If caching is enabled, but neither the default cache nor config.cache are set to a cache object, + * then the default `$cacheFactory("$http")` object is used. + * + * The default cache value can be set by updating the + * {@link ng.$http#defaults `$http.defaults.cache`} property or the + * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. + * + * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using + * the relevant cache object. The next time the same request is made, the response is returned + * from the cache without sending a request to the server. + * + * Take note that: + * + * * Only GET and JSONP requests are cached. + * * The cache key is the request URL including search parameters; headers are not considered. + * * Cached responses are returned asynchronously, in the same way as responses from the server. + * * If multiple identical requests are made using the same cache, which is not yet populated, + * one request will be made to the server and remaining requests will return the same response. + * * A cache-control header on the response does not affect if or how responses are cached. + * + * + * ## Interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication, or any kind of synchronous or + * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be + * able to intercept requests before they are handed to the server and + * responses before they are handed over to the application code that + * initiated these requests. The interceptors leverage the {@link ng.$q + * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. + * + * The interceptors are service factories that are registered with the `$httpProvider` by + * adding them to the `$httpProvider.interceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor. + * + * There are two kinds of interceptors (and two kinds of rejection interceptors): + * + * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to + * modify the `config` object or create a new one. The function needs to return the `config` + * object directly, or a promise containing the `config` or a new `config` object. + * * `requestError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * * `response`: interceptors get called with http `response` object. The function is free to + * modify the `response` object or create a new one. The function needs to return the `response` + * object directly, or as a promise containing the `response` or a new `response` object. + * * `responseError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * + * + * ```js + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return { + * // optional method + * 'request': function(config) { + * // do something on success + * return config; + * }, + * + * // optional method + * 'requestError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * }, + * + * + * + * // optional method + * 'response': function(response) { + * // do something on success + * return response; + * }, + * + * // optional method + * 'responseError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * } + * }; + * }); + * + * $httpProvider.interceptors.push('myHttpInterceptor'); + * + * + * // alternatively, register the interceptor via an anonymous factory + * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { + * return { + * 'request': function(config) { + * // same as above + * }, + * + * 'response': function(response) { + * // same as above + * } + * }; + * }); + * ``` + * + * ## Security Considerations + * + * When designing web applications, consider security threats from: + * + * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) + * + * Both server and the client must cooperate in order to eliminate these threats. Angular comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ### JSON Vulnerability Protection + * + * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * allows third party website to turn your JSON resource URL into + * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * Angular will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * ```js + * ['one','two'] + * ``` + * + * which is vulnerable to attack, your server can return: + * ```js + * )]}', + * ['one','two'] + * ``` + * + * Angular will strip the prefix, before processing the JSON. + * + * + * ### Cross Site Request Forgery (XSRF) Protection + * + * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by + * which the attacker can trick an authenticated user into unknowingly executing actions on your + * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the + * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP + * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the + * cookie, your server can be assured that the XHR came from JavaScript running on your domain. + * The header will not be set for cross-domain requests. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure + * that only JavaScript running on your domain could have sent the request. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) + * for added security. + * + * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName + * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, + * or the per-request config object. + * + * In order to prevent collisions in environments where multiple Angular apps share the + * same domain or subdomain, we recommend that each application uses unique cookie name. + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. + * - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized + * with the `paramSerializer` and appended as GET parameters. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings or functions which return strings representing + * HTTP headers to send to the server. If the return value of a function is null, the + * header will not be sent. Functions accept a config object as an argument. + * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object. + * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`. + * The handler will be called in the context of a `$apply` block. + * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload + * object. To bind events to the XMLHttpRequest object, use `eventHandlers`. + * The handler will be called in the context of a `$apply` block. + * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. + * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. + * - **transformRequest** – + * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – + * transform function or an array of such functions. The transform function takes the http + * request body and headers and returns its transformed (typically serialized) version. + * See {@link ng.$http#overriding-the-default-transformations-per-request + * Overriding the Default Transformations} + * - **transformResponse** – + * `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` – + * transform function or an array of such functions. The transform function takes the http + * response body, headers and status and returns its transformed (typically deserialized) version. + * See {@link ng.$http#overriding-the-default-transformations-per-request + * Overriding the Default Transformations} + * - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to + * prepare the string representation of request parameters (specified as an object). + * If specified as string, it is interpreted as function registered with the + * {@link $injector $injector}, which means you can create your own serializer + * by registering it as a {@link auto.$provide#service service}. + * The default serializer is the {@link $httpParamSerializer $httpParamSerializer}; + * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike} + * - **cache** – `{boolean|Object}` – A boolean value or object created with + * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response. + * See {@link $http#caching $http Caching} for more information. + * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} + * that should abort the request when resolved. + * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the + * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) + * for more information. + * - **responseType** - `{string}` - see + * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype). + * + * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object + * when the request succeeds or fails. + * + * + * @property {Array.<Object>} pendingRequests Array of config objects for currently pending + * requests.

So, for HTML elements interpolated + * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter + * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, + * this is typically useful only when user-data is used in rendering a template from the server, or + * when otherwise untrusted data is used by a directive. + * + * <example name="interpolation"> + * <file name="index.html"> + * <div ng-init="username='A user'"> + * <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\} + * </p> + * <p><strong>{{username}}</strong> attempts to inject code which will deface the + * application, but fails to accomplish their task, because the server has correctly + * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash) + * characters.</p> + * <p>Instead, the result of the attempted script injection is visible, and can be removed + * from the database by an administrator.</p> + * </div> + * </file> + * </example> + * + * @knownIssue + * It is currently not possible for an interpolated expression to contain the interpolation end + * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e. + * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string. + * + * @knownIssue + * All directives and components must use the standard `{{` `}}` interpolation symbols + * in their templates. If you change the application interpolation symbols the {@link $compile} + * service will attempt to denormalize the standard symbols to the custom symbols. + * The denormalization process is not clever enough to know not to replace instances of the standard + * symbols where they would not normally be treated as interpolation symbols. For example in the following + * code snippet the closing braces of the literal object will get incorrectly denormalized: + * + * ``` + * <div data-context='{"context":{"id":3,"type":"page"}}"> + * ``` + * + * The workaround is to ensure that such instances are separated by whitespace: + * ``` + * <div data-context='{"context":{"id":3,"type":"page"} }"> + * ``` + * + * See https://github.com/angular/angular.js/pull/14610#issuecomment-219401099 for more information. + * + * @param {string} text The text with markup to interpolate. + * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have + * embedded expression in order to return an interpolation function.

This is similar to the native Promise implementation from ES6, + * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). + * + * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are + * available yet. + * + * It can be used like so: + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * // perform some asynchronous operation, resolve or reject the promise when appropriate. + * return $q(function(resolve, reject) { + * setTimeout(function() { + * if (okToGreet(name)) { + * resolve('Hello, ' + name + '!'); + * } else { + * reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * }); + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }); + * ``` + * + * Note: progress/notify callbacks are not currently supported via the ES6-style interface. + * + * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. + * + * However, the more traditional CommonJS-style usage is still available, and documented below. + * + * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an + * interface for interacting with an object that represents the result of an action that is + * performed asynchronously, and may or may not be finished at any given point in time. + * + * From the perspective of dealing with error handling, deferred and promise APIs are to + * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * var deferred = $q.defer(); + * + * setTimeout(function() { + * deferred.notify('About to greet ' + name + '.'); + * + * if (okToGreet(name)) { + * deferred.resolve('Hello, ' + name + '!'); + * } else { + * deferred.reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * + * return deferred.promise; + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }, function(update) { + * alert('Got notification: ' + update); + * }); + * ``` + * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * # The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promise's execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * # The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved + * with the value which is resolved in that promise using + * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). + * It also notifies via the return value of the `notifyCallback` method. The promise cannot be + * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback + * arguments are optional. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * # Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * ```js + * promiseB = promiseA.then(function(result) { + * return result + 1; + * }); + * + * // promiseB will be resolved immediately after promiseA is resolved and its value + * // will be the result of promiseA incremented by 1 + * ``` + * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * # Differences between Kris Kowal's Q and $q + * + * There are two main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in angular, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * # Testing + * + * ```js + * it('should simulate promise', inject(function($q, $rootScope) { + * var deferred = $q.defer(); + * var promise = deferred.promise; + * var resolvedValue; + * + * promise.then(function(value) { resolvedValue = value; }); + * expect(resolvedValue).toBeUndefined(); + * + * // Simulate resolving of promise + * deferred.resolve(123); + * // Note that the 'then' function does not get called synchronously. + * // This is because we want the promise API to always be async, whether or not + * // it got called synchronously or asynchronously. + * expect(resolvedValue).toBeUndefined(); + * + * // Propagate promise resolution to 'then' functions using $apply(). + * $rootScope.$apply(); + * expect(resolvedValue).toEqual(123); + * })); + * ``` + * + * @param {function(function, function)} resolver Function which is responsible for resolving or + * rejecting the newly created promise.

One example of + * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer + * to these contexts as privileged or SCE contexts. + * + * As of version 1.2, Angular ships with SCE enabled by default. + * + * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow + * one to execute arbitrary javascript by the use of the expression() syntax. Refer + * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them. + * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>` + * to the top of your HTML document. + * + * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for + * security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * Here's an example of a binding in a privileged context: + * + * ``` + * <input ng-model="userHtml" aria-label="User input"> + * <div ng-bind-html="userHtml"></div> + * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV. + * In a more realistic example, one may be rendering user comments, blog articles, etc. via + * bindings. (HTML is just one example of a context where rendering user controlled input creates + * security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, you want to ensure that any such bindings are disallowed unless you can + * determine that something explicitly says it's safe to use a value for binding in that + * context. You can then audit your code (a simple grep would do) to ensure that this is only done + * for those values that you can easily tell are safe - because they were received from your server, + * sanitized by your library, etc. You can organize your codebase to help with this - perhaps + * allowing only the files in a specific directory to do this. Ensuring that the internal API + * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * obtain values that will be accepted by SCE / privileged contexts. + * + * + * ## How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the + * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ## Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, Angular only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ## This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g. + * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works. + * + * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them + * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * <a name="contexts"></a> + * ## What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. | + * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG`, `VIDEO`, `AUDIO`, `SOURCE`, and `TRACK` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a> + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ## Show me an example using SCE. + * + * <example module="mySceApp" deps="angular-sanitize.js" name="sce-service"> + * <file name="index.html"> + * <div ng-controller="AppController as myCtrl"> + * <i ng-bind-html="myCtrl.explicitlyTrustedHtml" id="explicitlyTrustedHtml"></i><br><br> + * <b>User comments</b><br> + * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when + * $sanitize is available.

All strings or + * objects with string properties in `array` that match this string will be returned. This also + * applies to nested object properties. + * The predicate can be negated by prefixing the string with `!`. + * + * - `Object`: A pattern object can be used to filter specific properties on objects contained + * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items + * which have property `name` containing "M" and property `phone` containing "1". A special + * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match + * against any property of the object or its nested object properties. That's equivalent to the + * simple substring match with a `string` as described above. The special property name can be + * overwritten, using the `anyPropertyKey` parameter. + * The predicate can be negated by prefixing the string with `!`. + * For example `{name: "!M"}` predicate will return an array of items which have property `name` + * not containing "M". + * + * Note that a named property will match properties on the same level only, while the special + * `$` property will match properties on the same level or deeper. E.g. an array item like + * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but + * **will** be matched by `{$: 'John'}`. + * + * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters. + * The function is called for each element of the array, with the element, its index, and + * the entire array itself as arguments. + * + * The final result is an array of those elements that the predicate returned true for. + * + * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in + * determining if the expected value (from the filter expression) and actual value (from + * the object in the array) should be considered a match. + * + * Can be one of: + * + * - `function(actual, expected)`: + * The function will be given the object value and the predicate value to compare and + * should return true if both values should be considered equal. + * + * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`. + * This is essentially strict comparison of expected and actual. + * + * - `false`: A short hand for a function which will look for a substring match in a case + * insensitive way. Primitive values are converted to strings.

The `expression` is evaluated against each item and the output is used + * for comparing with other items. + * + * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in + * ascending order. + * + * The comparison is done using the `comparator` function. If none is specified, a default, built-in + * comparator is used (see below for details - in a nutshell, it compares numbers numerically and + * strings alphabetically). + * + * ### Under the hood + * + * Ordering the specified `collection` happens in two phases: + * + * 1. All items are passed through the predicate (or predicates), and the returned values are saved + * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed + * through a predicate that extracts the value of the `label` property, would be transformed to: + * ``` + * { + * value: 'foo', + * type: 'string', + * index: ... + * } + * ``` + * 2. The comparator function is used to sort the items, based on the derived values, types and + * indices. + * + * If you use a custom comparator, it will be called with pairs of objects of the form + * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal + * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the + * second, or `1` otherwise. + * + * In order to ensure that the sorting will be deterministic across platforms, if none of the + * specified predicates can distinguish between two items, `orderBy` will automatically introduce a + * dummy predicate that returns the item's index as `value`. + * (If you are using a custom comparator, make sure it can handle this predicate as well.) + * + * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted + * value for an item, `orderBy` will try to convert that object to a primitive value, before passing + * it to the comparator. The following rules govern the conversion: + * + * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be + * used instead.<br /> + * (If the object has a `valueOf()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that + * returns a primitive, its return value will be used instead.<br /> + * (If the object has a `toString()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 3. No conversion; the object itself is used. + * + * ### The default comparator + * + * The default, built-in comparator should be sufficient for most usecases. In short, it compares + * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to + * using their index in the original collection, and sorts values of different types by type. + * + * More specifically, it follows these steps to determine the relative order of items: + * + * 1. If the compared values are of different types, compare the types themselves alphabetically. + * 2. If both values are of type `string`, compare them alphabetically in a case- and + * locale-insensitive way. + * 3. If both values are objects, compare their indices instead. + * 4. Otherwise, return: + * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). + * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). + * - `1`, otherwise. + * + * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being + * saved as numbers and not strings. + * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e. + * `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to + * other values. + * + * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. + * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of + * predicates) to be used by the comparator to determine the order of elements. + * + * Can be one of: + * + * - `Function`: A getter function. This function will be called with each item as argument and + * the return value will be used for sorting. + * - `string`: An Angular expression. This expression will be evaluated against each item and the + * result will be used for sorting. For example, use `'label'` to sort by a property called + * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` + * property.<br /> + * (The result of a constant expression is interpreted as a property name to be used for + * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a + * property called `special name`.)<br /> + * An expression can be optionally prefixed with `+` or `-` to control the sorting direction, + * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, + * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. + * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the + * relative order of two items, the next predicate is used as a tie-breaker. + * + * **Note:** If the predicate is missing or empty then it defaults to `'+'`. + * + * @param {boolean=} reverse - If `true`, reverse the sorting order. + * @param {(Function)=} comparator - The comparator function used to determine the relative order of + * value pairs. If omitted, the built-in comparator will be used. + * + * @returns {Array} - The sorted array. + * + * + * @example + * ### Ordering a table with `ngRepeat` + * + * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by + * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means + * it defaults to the built-in comparator. + * + <example name="orderBy-static" module="orderByExample1"> + <file name="index.html"> + <div ng-controller="ExampleController"> + <table class="friends"> + <tr> + <th>Name</th> + <th>Phone Number</th> + <th>Age</th> + </tr> + <tr ng-repeat="friend in friends | orderBy:'-age'"> + <td>{{friend.name}}</td> + <td>{{friend.phone}}</td> + <td>{{friend.age}}</td> + </tr> + </table> + </div> + </file> + <file name="script.js"> + angular.module('orderByExample1', []) + .controller('ExampleController', ['$scope', function($scope) { + $scope.friends = [ + {name: 'John', phone: '555-1212', age: 10}, + {name: 'Mary', phone: '555-9876', age: 19}, + {name: 'Mike', phone: '555-4321', age: 21}, + {name: 'Adam', phone: '555-5678', age: 35}, + {name: 'Julie', phone: '555-8765', age: 29} + ]; + }]); + </file> + <file name="style.css"> + .friends { + border-collapse: collapse; + } + + .friends th { + border-bottom: 1px solid; + } + .friends td, .friends th { + border-left: 1px solid; + padding: 5px 10px; + } + .friends td:first-child, .friends th:first-child { + border-left: none; + } + </file> + <file name="protractor.js" type="protractor"> + // Element locators + var names = element.all(by.repeater('friends').column('friend.name')); + + it('should sort friends by age in reverse order', function() { + expect(names.get(0).getText()).toBe('Adam'); + expect(names.get(1).getText()).toBe('Julie'); + expect(names.get(2).getText()).toBe('Mike'); + expect(names.get(3).getText()).toBe('Mary'); + expect(names.get(4).getText()).toBe('John'); + }); + </file> + </example> + * <hr /> + * + * @example + * ### Changing parameters dynamically + * + * All parameters can be changed dynamically.

This means that the outer form is valid when all of the child + * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so + * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to + * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group + * of controls needs to be determined. + * + * # CSS classes + * - `ng-valid` is set if the form is valid. + * - `ng-invalid` is set if the form is invalid. + * - `ng-pending` is set if the form is pending. + * - `ng-pristine` is set if the form is pristine. + * - `ng-dirty` is set if the form is dirty. + * - `ng-submitted` is set if the form was submitted. + * + * Keep in mind that ngAnimate can detect each of these classes when added and removed. + * + * + * # Submitting a form and preventing the default action + * + * Since the role of forms in client-side Angular applications is different than in classical + * roundtrip apps, it is desirable for the browser not to translate the form submission into a full + * page reload that sends the data to the server. Instead some javascript logic should be triggered + * to handle the form submission in an application-specific way. + * + * For this reason, Angular prevents the default action (form submission to the server) unless the + * `<form>` element has an `action` attribute specified. + * + * You can use one of the following two ways to specify what javascript method should be called when + * a form is submitted: + * + * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element + * - {@link ng.directive:ngClick ngClick} directive on the first + * button or input field of type submit (input[type=submit]) + * + * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} + * or {@link ng.directive:ngClick ngClick} directives. + * This is because of the following form submission rules in the HTML specification: + * + * - If a form has only one input field then hitting enter in this field triggers form submit + * (`ngSubmit`) + * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter + * doesn't trigger submit + * - if a form has one or more input fields and one or more buttons or input[type=submit] then + * hitting enter in any of the input fields will trigger the click handler on the *first* button or + * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) + * + * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is + * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * ## Animation Hooks + * + * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. + * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any + * other validations that are performed within the form. Animations in ngForm are similar to how + * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well + * as JS animations. + * + * The following example shows a simple way to utilize CSS transitions to style a form element + * that has been rendered as invalid after it has been validated: + * + * <pre> + * //be sure to include ngAnimate as a module to hook into more + * //advanced animations + * .my-form { + * transition:0.5s linear all; + * background: white; + * } + * .my-form.ng-invalid { + * background: red; + * color:white; + * } + * </pre> + * + * @example + <example name="ng-form" deps="angular-animate.js" animations="true" fixBase="true" module="formExample"> + <file name="index.html"> + <script> + angular.module('formExample', []) + .controller('FormController', ['$scope', function($scope) { + $scope.userType = 'guest'; + }]); + </script> + <style> + .my-form { + transition:all linear 0.5s; + background: transparent; + } + .my-form.ng-invalid { + background: red; + } + </style> + <form name="myForm" ng-controller="FormController" class="my-form"> + userType: <input name="input" ng-model="userType" required> + <span class="error" ng-show="myForm.input.$error.required">Required!</span><br> + <code>userType = {{userType}}</code><br> + <code>myForm.input.$valid = {{myForm.input.$valid}}</code><br> + <code>myForm.input.$error = {{myForm.input.$error}}</code><br> + <code>myForm.$valid = {{myForm.$valid}}</code><br> + <code>myForm.$error.required = {{!!myForm.$error.required}}</code><br> + </form> + </file> + <file name="protractor.js" type="protractor"> + it('should initialize to model', function() { + var userType = element(by.binding('userType')); + var valid = element(by.binding('myForm.input.$valid')); + + expect(userType.getText()).toContain('guest'); + expect(valid.getText()).toContain('true'); + }); + + it('should be invalid if empty', function() { + var userType = element(by.binding('userType')); + var valid = element(by.binding('myForm.input.$valid')); + var userInput = element(by.model('userType')); + + userInput.clear(); + userInput.sendKeys(''); + + expect(userType.getText()).toEqual('userType ='); + expect(valid.getText()).toContain('false'); + }); + </file> + </example> + * + * @param {string=} name Name of the form.

E.g.: + * `<input type="range" ng-input-range ... />` + * </p><br /> + * <p> + * Input elements without the `ng-input-range` attibute will continue to be treated the same + * as in previous versions (e.g. their model value will be a string not a number and Angular + * will not take `min`/`max`/`step` attributes and properties into account). + * </p><br /> + * <p> + * **Note:** From v1.6.x onwards, the support for `input[range]` will be always enabled and + * the `ng-input-range` attribute will have no effect. + * </p><br /> + * <p> + * This documentation page refers to elements which have the built-in support enabled; i.e. + * elements _with_ the `ng-input-range` attribute. + * </p> + * </div> + * + * The model for the range input must always be a `Number`. + * + * IE9 and other browsers that do not support the `range` type fall back + * to a text input without any default values for `min`, `max` and `step`. Model binding, + * validation and number parsing are nevertheless supported. + * + * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]` + * in a way that never allows the input to hold an invalid value. That means: + * - any non-numerical value is set to `(max + min) / 2`. + * - any numerical value that is less than the current min val, or greater than the current max val + * is set to the min / max val respectively. + * - additionally, the current `step` is respected, so the nearest value that satisfies a step + * is used. + * + * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range)) + * for more info. + * + * This has the following consequences for Angular: + * + * Since the element value should always reflect the current model value, a range input + * will set the bound ngModel expression to the value that the browser has set for the + * input element. For example, in the following input `<input type="range" ng-input-range ng-model="model.value">`, + * if the application sets `model.value = null`, the browser will set the input to `'50'`. + * Angular will then set the model to `50`, to prevent input and model value being out of sync. + * + * That means the model for range will immediately be set to `50` after `ngModel` has been + * initialized. It also means a range input can never have the required error. + * + * This does not only affect changes to the model value, but also to the values of the `min`, + * `max`, and `step` attributes. When these change in a way that will cause the browser to modify + * the input value, Angular will also update the model value. + * + * Automatic value adjustment also means that a range input element can never have the `required`, + * `min`, or `max` errors. + * + * However, `step` is currently only fully implemented by Firefox. Other browsers have problems + * when the step value changes dynamically - they do not adjust the element value correctly, but + * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step` + * error on the input, and set the model to `undefined`. + * + * Note that `input[range]` is not compatible with `ngMax`, `ngMin`, and `ngStep`, because they do + * not set the `min` and `max` attributes, which means that the browser won't automatically adjust + * the input value based on their values, and will always assume min = 0, max = 100, and step = 1. + * + * @param ngInputRange The presense of this attribute enables the built-in support for + * `input[range]`. + * @param {string} ngModel Assignable angular expression to data-bind to. + * @param {string=} name Property name of the form under which the control is published. + * @param {string=} min Sets the `min` validation to ensure that the value entered is greater + * than `min`.

If the expression evaluates to a string, the string should be one or more space-delimited class + * names. + * + * 2. If the expression evaluates to an object, then for each key-value pair of the + * object with a truthy value the corresponding key is used as a class name. + * + * 3. If the expression evaluates to an array, each element of the array should either be a string as in + * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array + * to give you more control over what CSS classes appear. See the code below for an example of this. + * + * + * The directive won't add duplicate classes if a particular class was already set. + * + * When the expression changes, the previously added classes are removed and only then are the + * new classes added. + * + * @knownIssue + * You should not use {@link guide/interpolation interpolation} in the value of the `class` + * attribute, when using the `ngClass` directive on the same element. + * See {@link guide/interpolation#known-issues here} for more info. + * + * @animations + * | Animation | Occurs | + * |----------------------------------|-------------------------------------| + * | {@link ng.$animate#addClass addClass} | just before the class is applied to the element | + * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element | + * + * @element ANY + * @param {expression} ngClass {@link guide/expression Expression} to eval.

Adding, removing, clearing, and + * greeting are methods declared on the controller (see source tab). These methods can + * easily be called from the angular markup. Any changes to the data are automatically reflected + * in the View without the need for a manual update. + * + * Two different declaration styles are included below: + * + * * one binds methods and properties directly onto the controller using `this`: + * `ng-controller="SettingsController1 as settings"` + * * one injects `$scope` into the controller: + * `ng-controller="SettingsController2"` + * + * The second option is more common in the Angular community, and is generally used in boilerplates + * and in this guide.

Angular makes use of this in the {@link $parse} service to + * provide a 30% increase in the speed of evaluating Angular expressions. (This CSP rule can be + * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would + * weaken the protections offered by CSP.) + * + * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden. + * This prevents apps from injecting custom styles directly into the document. Angular makes use of + * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these + * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css` + * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but + * it is generally not recommended as it would weaken the protections offered by CSP.) + * + * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking dynamic code + * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically + * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a + * CSP error to be logged in the console: + * + * ``` + * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of + * script in the following Content Security Policy directive: "default-src 'self'". Note that + * 'script-src' was not explicitly set, so 'default-src' is used as a fallback. + * ``` + * + * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp` + * directive on an element of the HTML document that appears before the `<script>` tag that loads + * the `angular.js` file. + * + * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.* + * + * You can specify which of the CSP related Angular features should be deactivated by providing + * a value for the `ng-csp` attribute. The options are as follows: + * + * * no-inline-style: this stops Angular from injecting CSS styles into the DOM + * + * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings + * + * You can use these values in the following combinations: + * + * + * * No declaration means that Angular will assume that you can do inline styles, but it will do + * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous + * versions of Angular. + * + * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline + * styles and unsafe eval. E.g. `<body ng-csp>`.

If the expression assigned to `ngIf` evaluates to a false + * value then the element is removed from the DOM, otherwise a clone of the + * element is reinserted into the DOM. + * + * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the + * element in the DOM rather than changing its visibility via the `display` css property. A common + * case when this difference is significant is when using css selectors that rely on an element's + * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes. + * + * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope + * is created when the element is restored. The scope created within `ngIf` inherits from + * its parent scope using + * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance). + * An important implication of this is if `ngModel` is used within `ngIf` to bind to + * a javascript primitive defined in the parent scope. In this case any modifications made to the + * variable within the child scope will override (hide) the value in the parent scope. + * + * Also, `ngIf` recreates elements using their compiled state. An example of this behavior + * is if an element's class attribute is directly modified after it's compiled, using something like + * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element + * the added class will be lost because the original compiled state is used to regenerate the element. + * + * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter` + * and `leave` effects. + * + * @animations + * | Animation | Occurs | + * |----------------------------------|-------------------------------------| + * | {@link ng.$animate#enter enter} | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container | + * | {@link ng.$animate#leave leave} | just before the `ngIf` contents are removed from the DOM | + * + * @element ANY + * @scope + * @priority 600 + * @param {expression} ngIf If the {@link guide/expression expression} is falsy then + * the element is removed from the DOM tree.

These classes include: `.ng-pristine`, `.ng-dirty`, + * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself. + * The animations that are triggered within ngModel are similar to how they work in ngClass and + * animations can be hooked into using CSS transitions, keyframes as well as JS animations. + * + * The following example shows a simple way to utilize CSS transitions to style an input element + * that has been rendered as invalid after it has been validated: + * + * <pre> + * //be sure to include ngAnimate as a module to hook into more + * //advanced animations + * .my-input { + * transition:0.5s linear all; + * background: white; + * } + * .my-input.ng-invalid { + * background: red; + * color:white; + * } + * </pre> + * + * @example + * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model"> + <file name="index.html"> + <script> + angular.module('inputExample', []) + .controller('ExampleController', ['$scope', function($scope) { + $scope.val = '1'; + }]); + </script> + <style> + .my-input { + transition:all linear 0.5s; + background: transparent; + } + .my-input.ng-invalid { + color:white; + background: red; + } + </style> + <p id="inputDescription"> + Update input to see transitions when valid/invalid. + Integer is a valid value. + </p> + <form name="testForm" ng-controller="ExampleController"> + <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input" + aria-describedby="inputDescription" /> + </form> + </file> + * </example> + * + * ## Binding to a getter/setter + * + * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a + * function that returns a representation of the model when called with zero arguments, and sets + * the internal state of a model when called with an argument. It's sometimes useful to use this + * for models that have an internal representation that's different from what the model exposes + * to the view. + * + * <div class="alert alert-success"> + * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more + * frequently than other parts of your code. + * </div> + * + * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that + * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to + * a `<form>`, which will enable this behavior for all `<input>`s within it.

This means that if you update the model you + * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in + * order to make sure it is synchronized with the model and that any debounced action is canceled. + * + * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`} + * method is by making sure the input is placed inside a form that has a `name` attribute. This is + * important because `form` controllers are published to the related scope under the name in their + * `name` attribute. + * + * Any pending changes will take place immediately when an enclosing form is submitted via the + * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * `ngModelOptions` has an effect on the element it's declared on and its descendants. + * + * @param {Object} ngModelOptions options to apply to the current model.

A + * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a + * custom value for each event. For example: + * `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"` + * - `allowInvalid`: boolean value which indicates that the model can be set with values that did + * not validate correctly instead of the default behavior of setting the model to undefined. + * - `getterSetter`: boolean value which determines whether or not to treat functions bound to + `ngModel` as getters/setters. + * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for + * `<input type="date">`, `<input type="time">`, ... .

This is because an option element can only be bound to string values at + * present. + * + * When an item in the `<select>` menu is selected, the array element or object property + * represented by the selected option will be bound to the model identified by the `ngModel` + * directive. + * + * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can + * be nested into the `<select>` element. This element will then represent the `null` or "not selected" + * option. See example below for demonstration. + * + * ## Complex Models (objects or collections) + * + * By default, `ngModel` watches the model by reference, not value. This is important to know when + * binding the select to a model that is an object or a collection. + * + * One issue occurs if you want to preselect an option. For example, if you set + * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection, + * because the objects are not identical. So by default, you should always reference the item in your collection + * for preselections, e.g.: `$scope.selected = $scope.collection[3]`. + * + * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity + * of the item not by reference, but by the result of the `track by` expression. For example, if your + * collection items have an id property, you would `track by item.id`. + * + * A different issue with objects or collections is that ngModel won't detect if an object property or + * a collection item changes. For that reason, `ngOptions` additionally watches the model using + * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute. + * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection + * has not changed identity, but only a property on the object or an item in the collection changes. + * + * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection + * if the model is an array). This means that changing a property deeper than the first level inside the + * object/collection will not trigger a re-rendering. + * + * ## `select` **`as`** + * + * Using `select` **`as`** will bind the result of the `select` expression to the model, but + * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources) + * or property name (for object data sources) of the value within the collection. If a **`track by`** expression + * is used, the result of that expression will be set as the value of the `option` and `select` elements. + * + * + * ### `select` **`as`** and **`track by`** + * + * <div class="alert alert-warning"> + * Be careful when using `select` **`as`** and **`track by`** in the same expression. + * </div> + * + * Given this array of items on the $scope: + * + * ```js + * $scope.items = [{ + * id: 1, + * label: 'aLabel', + * subItem: { name: 'aSubItem' } + * }, { + * id: 2, + * label: 'bLabel', + * subItem: { name: 'bSubItem' } + * }]; + * ``` + * + * This will work: + * + * ```html + * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select> + * ``` + * ```js + * $scope.selected = $scope.items[0]; + * ``` + * + * but this will not work: + * + * ```html + * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select> + * ``` + * ```js + * $scope.selected = $scope.items[0].subItem; + * ``` + * + * In both examples, the **`track by`** expression is applied successfully to each `item` in the + * `items` array.

In the first example, the + * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with + * no issue.

You configure ngPluralize directive + * by specifying the mappings between + * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) + * and the strings to be displayed. + * + * # Plural categories and explicit number rules + * There are two + * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) + * in Angular's default en-US locale: "one" and "other". + * + * While a plural category may match many numbers (for example, in en-US locale, "other" can match + * any number that is not 1), an explicit number rule can only match one number. For example, the + * explicit number rule for "3" matches the number 3. There are examples of plural categories + * and explicit number rules throughout the rest of this documentation. + * + * # Configuring ngPluralize + * You configure ngPluralize by providing 2 attributes: `count` and `when`. + * You can also provide an optional attribute, `offset`. + * + * The value of the `count` attribute can be either a string or an {@link guide/expression + * Angular expression}; these are evaluated on the current scope for its bound value. + * + * The `when` attribute specifies the mappings between plural categories and the actual + * string to be displayed. The value of the attribute should be a JSON object. + * + * The following example shows how to configure ngPluralize: + * + * ```html + * <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + * 'one': '1 person is viewing.', + * 'other': '{} people are viewing.'}"> + * </ng-pluralize> + *``` + * + * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not + * specify this rule, 0 would be matched to the "other" category and "0 people are viewing" + * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for + * other numbers, for example 12, so that instead of showing "12 people are viewing", you can + * show "a dozen people are viewing". + * + * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted + * into pluralized strings. In the previous example, Angular will replace `{}` with + * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder + * for <span ng-non-bindable>{{numberExpression}}</span>. + * + * If no rule is defined for a category, then an empty string is displayed and a warning is generated. + * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`. + * + * # Configuring ngPluralize with offset + * The `offset` attribute allows further customization of pluralized text, which can result in + * a better user experience. For example, instead of the message "4 people are viewing this document", + * you might display "John, Kate and 2 others are viewing this document". + * The offset attribute allows you to offset a number by any desired value. + * Let's take a look at an example: + * + * ```html + * <ng-pluralize count="personCount" offset=2 + * when="{'0': 'Nobody is viewing.', + * '1': '{{person1}} is viewing.', + * '2': '{{person1}} and {{person2}} are viewing.', + * 'one': '{{person1}}, {{person2}} and one other person are viewing.', + * 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + * </ng-pluralize> + * ``` + * + * Notice that we are still using two plural categories(one, other), but we added + * three explicit number rules 0, 1 and 2. + * When one person, perhaps John, views the document, "John is viewing" will be shown. + * When three people view the document, no explicit number rule is found, so + * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category. + * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing" + * is shown. + * + * Note that when you specify offsets, you must provide explicit number rules for + * numbers from 0 up to and including the offset. If you use an offset of 3, for example, + * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for + * plural categories "one" and "other". + * + * @param {string|expression} count The variable to be bound to. + * @param {string} when The mapping between plural category to its corresponding strings. + * @param {number=} offset Offset to deduct from the total number. + * + * @example + <example module="pluralizeExample" name="ng-pluralize"> + <file name="index.html"> + <script> + angular.module('pluralizeExample', []) + .controller('ExampleController', ['$scope', function($scope) { + $scope.person1 = 'Igor'; + $scope.person2 = 'Misko'; + $scope.personCount = 1; + }]); + </script> + <div ng-controller="ExampleController"> + <label>Person 1:<input type="text" ng-model="person1" value="Igor" /></label><br/> + <label>Person 2:<input type="text" ng-model="person2" value="Misko" /></label><br/> + <label>Number of People:<input type="text" ng-model="personCount" value="1" /></label><br/> + + <!--- Example with simple pluralization rules for en locale ---> + Without Offset: + <ng-pluralize count="personCount" + when="{'0': 'Nobody is viewing.', + 'one': '1 person is viewing.', + 'other': '{} people are viewing.'}"> + </ng-pluralize><br> + + <!--- Example with offset ---> + With Offset(2): + <ng-pluralize count="personCount" offset=2 + when="{'0': 'Nobody is viewing.', + '1': '{{person1}} is viewing.', + '2': '{{person1}} and {{person2}} are viewing.', + 'one': '{{person1}}, {{person2}} and one other person are viewing.', + 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> + </ng-pluralize> + </div> + </file> + <file name="protractor.js" type="protractor"> + it('should show correct pluralized string', function() { + var withoutOffset = element.all(by.css('ng-pluralize')).get(0); + var withOffset = element.all(by.css('ng-pluralize')).get(1); + var countInput = element(by.model('personCount')); + + expect(withoutOffset.getText()).toEqual('1 person is viewing.'); + expect(withOffset.getText()).toEqual('Igor is viewing.'); + + countInput.clear(); + countInput.sendKeys('0'); + + expect(withoutOffset.getText()).toEqual('Nobody is viewing.'); + expect(withOffset.getText()).toEqual('Nobody is viewing.'); + + countInput.clear(); + countInput.sendKeys('2'); + + expect(withoutOffset.getText()).toEqual('2 people are viewing.'); + expect(withOffset.getText()).toEqual('Igor and Misko are viewing.'); + + countInput.clear(); + countInput.sendKeys('3'); + + expect(withoutOffset.getText()).toEqual('3 people are viewing.'); + expect(withOffset.getText()).toEqual('Igor, Misko and one other person are viewing.'); + + countInput.clear(); + countInput.sendKeys('4'); + + expect(withoutOffset.getText()).toEqual('4 people are viewing.'); + expect(withOffset.getText()).toEqual('Igor, Misko and 2 other people are viewing.'); + }); + it('should show data-bound names', function() { + var withOffset = element.all(by.css('ng-pluralize')).get(1); + var personCount = element(by.model('personCount')); + var person1 = element(by.model('person1')); + var person2 = element(by.model('person2')); + personCount.clear(); + personCount.sendKeys('4'); + person1.clear(); + person1.sendKeys('Di'); + person2.clear(); + person2.sendKeys('Vojta'); + expect(withOffset.getText()).toEqual('Di, Vojta and 2 other people are viewing.'); + }); + </file> + </example> + */ +var ngPluralizeDirective = ['$locale', '$interpolate', '$log', function($locale, $interpolate, $log) { + var BRACE = /{}/g, + IS_WHEN = /^when(Minus)?(.+)$/; + + return { + link: function(scope, element, attr) { + var numberExp = attr.count, + whenExp = attr.$attr.when && element.attr(attr.$attr.when), // we have {{}} in attrs + offset = attr.offset || 0, + whens = scope.$eval(whenExp) || {}, + whensExpFns = {}, + startSymbol = $interpolate.startSymbol(), + endSymbol = $interpolate.endSymbol(), + braceReplacement = startSymbol + numberExp + '-' + offset + endSymbol, + watchRemover = angular.noop, + lastCount; + + forEach(attr, function(expression, attributeName) { + var tmpMatch = IS_WHEN.exec(attributeName); + if (tmpMatch) { + var whenKey = (tmpMatch[1] ?

Browsers generally follow the strategy of providing + * keys in the order in which they were defined, although there are exceptions when keys are deleted + * and reinstated. See the + * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes). + * + * - `ngRepeat` will silently *ignore* object keys starting with `$`, because + * it's a prefix used by Angular for public (`$`) and private (`$$`) properties. + * + * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with + * objects, and will throw an error if used with one. + * + * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array + * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could + * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter) + * or implement a `$watch` on the object yourself. + * + * + * # Tracking and Duplicates + * + * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in + * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM: + * + * * When an item is added, a new instance of the template is added to the DOM. + * * When an item is removed, its template instance is removed from the DOM. + * * When items are reordered, their respective templates are reordered in the DOM. + * + * To minimize creation of DOM elements, `ngRepeat` uses a function + * to "keep track" of all items in the collection and their corresponding DOM elements. + * For example, if an item is added to the collection, `ngRepeat` will know that all other items + * already have DOM elements, and will not re-render them. + * + * The default tracking function (which tracks items by their identity) does not allow + * duplicate items in arrays. This is because when there are duplicates, it is not possible + * to maintain a one-to-one mapping between collection items and DOM elements. + * + * If you do need to repeat duplicate items, you can substitute the default tracking behavior + * with your own using the `track by` expression. + * + * For example, you may track items by the index of each item in the collection, using the + * special scope property `$index`: + * ```html + * <div ng-repeat="n in [42, 42, 43, 43] track by $index"> + * {{n}} + * </div> + * ``` + * + * You may also use arbitrary expressions in `track by`, including references to custom functions + * on the scope: + * ```html + * <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)"> + * {{n}} + * </div> + * ``` + * + * <div class="alert alert-success"> + * If you are working with objects that have a unique identifier property, you should track + * by this identifier instead of the object instance. Should you reload your data later, `ngRepeat` + * will not have to rebuild the DOM elements for items it has already rendered, even if the + * JavaScript objects in the collection have been substituted for new ones. For large collections, + * this significantly improves rendering performance.

These + * formats are currently supported: + * + * * `variable in expression` – where variable is the user defined loop variable and `expression` + * is a scope expression giving the collection to enumerate. + * + * For example: `album in artist.albums`. + * + * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers, + * and `expression` is the scope expression giving the collection to enumerate. + * + * For example: `(name, age) in {'adam':10, 'amalie':12}`. + * + * * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression + * which can be used to associate the objects in the collection with the DOM elements. If no tracking expression + * is specified, ng-repeat associates elements by identity. It is an error to have + * more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are + * mapped to the same DOM element, which is not possible.) + * + * Note that the tracking expression must come last, after any filters, and the alias expression. + * + * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements + * will be associated by item identity in the array. + * + * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique + * `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements + * with the corresponding item in the array by identity. Moving the same object in array would move the DOM + * element in the same way in the DOM. + * + * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this + * case the object identity does not matter. Two objects are considered equivalent as long as their `id` + * property is same. + * + * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter + * to items in conjunction with a tracking expression. + * + * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the + * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message + * when a filter is active on the repeater, but the filtered result set is empty. + * + * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after + * the items have been processed through the filter. + * + * Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end + * (and not as operator, inside an expression). + * + * For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` . + * + * @example + * This example uses `ngRepeat` to display a list of people.

This system works like the animation system present with + * `ngClass` except that you must also include the `!important` flag to override the display + * property so that the elements are not actually hidden during the animation. + * + * ```css + * /* A working example can be found at the bottom of this page. */ + * .my-element.ng-hide-add, .my-element.ng-hide-remove { + * transition: all 0.5s linear; + * } + * + * .my-element.ng-hide-add { ... } + * .my-element.ng-hide-add.ng-hide-add-active { ... } + * .my-element.ng-hide-remove { ... } + * .my-element.ng-hide-remove.ng-hide-remove-active { ... } + * ``` + * + * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property + * to block during animation states - ngAnimate will automatically handle the style toggling for you. + * + * @animations + * | Animation | Occurs | + * |-----------------------------------------------------|------------------------------------------------------------------------------------------------------------| + * | {@link $animate#addClass addClass} `.ng-hide` | After the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden. | + * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible. | + * + * + * @element ANY + * @param {expression} ngHide If the {@link guide/expression expression} is truthy/falsy then the + * element is hidden/shown respectively. + * + * @example + * A simple example, animating the element's opacity: + * + <example module="ngAnimate" deps="angular-animate.js" animations="true" name="ng-hide-simple"> + <file name="index.html"> + Hide: <input type="checkbox" ng-model="checked" aria-label="Toggle ngHide"><br /> + <div class="check-element animate-show-hide" ng-hide="checked"> + I hide when your checkbox is checked. + </div> + </file> + <file name="animations.css"> + .animate-show-hide.ng-hide { + opacity: 0; + } + + .animate-show-hide.ng-hide-add, + .animate-show-hide.ng-hide-remove { + transition: all linear 0.5s; + } + + .check-element { + border: 1px solid black; + opacity: 1; + padding: 10px; + } + </file> + <file name="protractor.js" type="protractor"> + it('should check ngHide', function() { + var checkbox = element(by.model('checked')); + var checkElem = element(by.css('.check-element')); + + expect(checkElem.isDisplayed()).toBe(true); + checkbox.click(); + expect(checkElem.isDisplayed()).toBe(false); + }); + </file> + </example> + * + * <hr /> + * @example + * A more complex example, featuring different show/hide animations: + * + <example module="ngAnimate" deps="angular-animate.js" animations="true" name="ng-hide-complex"> + <file name="index.html"> + Hide: <input type="checkbox" ng-model="checked" aria-label="Toggle ngHide"><br /> + <div class="check-element funky-show-hide" ng-hide="checked"> + I hide when your checkbox is checked. + </div> + </file> + <file name="animations.css"> + body { + overflow: hidden; + perspective: 1000px; + } + + .funky-show-hide.ng-hide-add { + transform: rotateZ(0); + transform-origin: right; + transition: all 0.5s ease-in-out; + } + + .funky-show-hide.ng-hide-add.ng-hide-add-active { + transform: rotateZ(-135deg); + } + + .funky-show-hide.ng-hide-remove { + transform: rotateY(90deg); + transform-origin: left; + transition: all 0.5s ease; + } + + .funky-show-hide.ng-hide-remove.ng-hide-remove-active { + transform: rotateY(0); + } + + .check-element { + border: 1px solid black; + opacity: 1; + padding: 10px; + } + </file> + <file name="protractor.js" type="protractor"> + it('should check ngHide', function() { + var checkbox = element(by.model('checked')); + var checkElem = element(by.css('.check-element')); + + expect(checkElem.isDisplayed()).toBe(true); + checkbox.click(); + expect(checkElem.isDisplayed()).toBe(false); + }); + </file> + </example> + */ +var ngHideDirective = ['$animate', function($animate) { + return { + restrict: 'A', + multiElement: true, + link: function(scope, element, attr) { + scope.$watch(attr.ngHide, function ngHideWatchAction(value) { + // The comment inside of the ngShowDirective explains why we add and + // remove a temporary class for the show/hide animation + $animate[value ?
