* Omitted or undefined options will leave the corresponding configuration values unchanged.
*
* @param {Object=} config - The configuration object. May only contain the options that need to be
* updated. Supported keys:
*
* * `objectMaxDepth` **{Number}** - The max depth for stringifying objects. Setting to a
* non-positive or non-numeric value, removes the max depth limit.
* Default: 5
*
* * `urlErrorParamsEnabled` **{Boolean}** - Specifies wether the generated error url will
* contain the parameters of the thrown error. Disabling the parameters can be useful if the
* generated error url is very long.
*
* Default: true. When used without argument, it returns the current value.

*
* var exampleMinErr = minErr('example');
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar);

* The above creates an instance of minErr in the example namespace. The

* resulting error will replace {0} with the value of foo, and {1} with the
* value of bar. The object is not restricted in the number of arguments it can
* take.
*
* If fewer arguments are specified than necessary for interpolation, the extra
* interpolation markers will be preserved in the final string.
*
* Since data will be parsed statically during a build step, some restrictions
* are applied with respect to how minErr instances are created and called.
* Instances should have names of the form namespaceMinErr for a minErr created
* using minErr('namespace') . Error codes, namespaces and template strings
* should all be static strings, not variables or general expressions.

* @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
* created in "strict-di" mode. This means that the application will fail to invoke functions which

* in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
* tracking down the root of these bugs.
*
* @description
*
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
* designates the **root element** of the application and is typically placed near the root element
* of the page - e.g. on the `` or `` tags.
*
* There are a few things to keep in mind when using `ngApp`:
* - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
* found in the document will be used to define the root element to auto-bootstrap as an
* application. To run multiple applications in an HTML document you must manually bootstrap them using
* {@link angular.bootstrap} instead.
* - AngularJS applications cannot be nested within each other.
* - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
* This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
* {@link ngRoute.ngView `ngView`}.
* Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
* causing animations to stop working and making the injector inaccessible from outside the app.
*
* You can specify an **AngularJS module** to be used as the root module for the application. This
* module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
* should contain the application code needed or have dependencies on other modules that will
* contain the code. See {@link angular.module} for more information.
*
* In the example below if the `ngApp` directive were not placed on the `html` element then the
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
* would not be resolved to `3`.
*
* @example
*
* ### Simple Usage
*
* `ngApp` is the easiest, and most common way to bootstrap an application.
*
I can add: {{a}} + {{b}} = {{ a+b }}
angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
$scope.a = 1;
$scope.b = 2;
});
*
* @example
*
* ### With `ngStrictDi`
*
* Using `ngStrictDi`, you would see something like this:
*
I can add: {{a}} + {{b}} = {{ a+b }}
This renders because the controller does not fail to
instantiate, by using explicit annotation style (see
script.js for details)
Name:
Hello, {{name}}!
This renders because the controller does not fail to
instantiate, by using explicit annotation style
(see script.js for details)
I can add: {{a}} + {{b}} = {{ a+b }}
The controller could not be instantiated, due to relying
on automatic function annotations (which are disabled in
strict mode). As such, the content of this section is not
interpolated, and there should be an error in your web console.
angular.module('ngAppStrictDemo', [])
// BadController will fail to instantiate, due to relying on automatic function annotation,
// rather than an explicit annotation
.controller('BadController', function($scope) {
$scope.a = 1;
$scope.b = 2;
})
// Unlike BadController, GoodController1 and GoodController2 will not fail to be instantiated,
// due to using explicit annotations using the array style and $inject property, respectively.
.controller('GoodController1', ['$scope', function($scope) {
$scope.a = 1;
$scope.b = 2;

* The `angular.module` is a global place for creating, registering and retrieving AngularJS
* modules.
* All modules (AngularJS core or 3rd party) that should be available to an application must be
* registered using this mechanism.
*
* Passing one argument retrieves an existing {@link angular.Module},
* whereas passing more than one argument creates a new {@link angular.Module}
*
*
* # Module
*
* A module is a collection of services, directives, controllers, filters, and configuration information.
* `angular.module` is used to configure the {@link auto.$injector $injector}.
*
* ```js
* // Create a new module
* var myModule = angular.module('myModule', []);
*
* // register a new service
* myModule.value('appName', 'MyCoolApp');
*
* // configure existing services inside initialization blocks.
* myModule.config(['$locationProvider', function($locationProvider) {
* // Configure existing providers
* $locationProvider.hashPrefix('!');
* }]);
* ```
*
* Then you can create an injector and load your modules like this:
*
* ```js
* var injector = angular.injector(['ng', 'myModule'])
* ```
*
* However it's more likely that you'll just use
* {@link ng.directive:ngApp ngApp} or
* {@link angular.bootstrap} to simplify this process for you.
*
* @param {!string} name The name of the module to create or retrieve.
* @param {!Array.=} requires If specified then new module is being created. If
* unspecified then the module is being retrieved for further configuration.
* @param {Function=} configFn Optional configuration function for the module. Same as
* {@link angular.Module#config Module#config()}.
* @returns {angular.Module} new module with the {@link angular.Module} api.

/**
* @ngdoc function
* @name angular.element
* @module ng
* @kind function
*
* @description
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
*
* If jQuery is available, `angular.element` is an alias for the
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
* delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
*
* jqLite is a tiny, API-compatible subset of jQuery that allows
* AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
* commonly needed functionality with the goal of having a very small footprint.
*
* To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
* {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
* specific version of jQuery if multiple versions exist on the page.
*
*
**Note:** All element references in AngularJS are always wrapped with jQuery or
* jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
*
*
**Note:** Keep in mind that this function will not find elements
* by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
* or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
*
* ## AngularJS's jqLite
* jqLite provides only the following jQuery methods:
*
* - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
* - [`after()`](http://api.jquery.com/after/)
* - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements
* so will not work correctly when invoked on a jqLite object containing more than one DOM node
* - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
* - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors
* - [`clone()`](http://api.jquery.com/clone/)
* - [`contents()`](http://api.jquery.com/contents/)
* - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
* As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
* - [`data()`](http://api.jquery.com/data/)
* - [`detach()`](http://api.jquery.com/detach/)
* - [`empty()`](http://api.jquery.com/empty/)
* - [`eq()`](http://api.jquery.com/eq/)
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
* - [`hasClass()`](http://api.jquery.com/hasClass/)
* - [`html()`](http://api.jquery.com/html/)
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
* - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
* - [`prepend()`](http://api.jquery.com/prepend/)
* - [`prop()`](http://api.jquery.com/prop/)
* - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
* - [`remove()`](http://api.jquery.com/remove/)
* - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
* - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
* - [`removeData()`](http://api.jquery.com/removeData/)
* - [`replaceWith()`](http://api.jquery.com/replaceWith/)
* - [`text()`](http://api.jquery.com/text/)
* - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
* - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
* - [`val()`](http://api.jquery.com/val/)
* - [`wrap()`](http://api.jquery.com/wrap/)
*
* ## jQuery/jqLite Extras
* AngularJS also provides the following additional methods and events to both jQuery and jqLite:
*
* ### Events
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
* on all DOM nodes being removed. 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. See
* https://github.com/angular/angular.js/issues/14251 for more information.
*
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
* @returns {Object} jQuery object.

/**
* @ngdoc service
* @name $injector
*
* @description
*
* `$injector` is used to retrieve object instances as defined by
* {@link auto.$provide provider}, instantiate types, invoke methods,
* and load modules.
*
* The following always holds true:
*
* ```js
* var $injector = angular.injector();
* expect($injector.get('$injector')).toBe($injector);
* expect($injector.invoke(function($injector) {
* return $injector;
* })).toBe($injector);
* ```
*
* ## Injection Function Annotation
*
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
* following are all valid ways of annotating function with injection arguments and are equivalent.
*
* ```js
* // inferred (only works if code not minified/obfuscated)
* $injector.invoke(function(serviceA){});
*
* // annotated
* function explicit(serviceA) {};
* explicit.$inject = ['serviceA'];
* $injector.invoke(explicit);
*
* // inline
* $injector.invoke(['serviceA', function(serviceA){}]);
* ```
*
* ### Inference
*
* In JavaScript calling `toString()` on a function returns the function definition. The definition
* can then be parsed and the function arguments can be extracted. This method of discovering
* annotations is disallowed when the injector is in strict mode.
* *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
* argument names.
*
* ### `$inject` Annotation
* By adding an `$inject` property onto a function the injection parameters can be specified.
*
* ### Inline
* As an array of injection names, where the last item in the array is the function to call.

/**
* @ngdoc method
* @name $injector#annotate
*
* @description
* Returns an array of service names which the function is requesting for injection. This API is
* used by the injector to determine which services need to be injected into the function when the
* function is invoked. There are three ways in which the function can be annotated with the needed
* dependencies.
*
* #### Argument names
*
* The simplest form is to extract the dependencies from the arguments of the function. This is done
* by converting the function into a string using `toString()` method and extracting the argument
* names.
* ```js
* // Given
* function MyController($scope, $route) {
* // ...
* }
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* ```
*
* You can disallow this method by using strict injection mode.
*
* This method does not work with code minification / obfuscation. For this reason the following
* annotation strategies are supported.
*
* #### The `$inject` property
*
* If a function has an `$inject` property and its value is an array of strings, then the strings
* represent names of services to be injected into the function.
* ```js
* // Given
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
* // ...
* }
* // Define function dependencies
* MyController['$inject'] = ['$scope', '$route'];
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* ```
*
* #### The array notation
*
* It is often desirable to inline Injected functions and that's when setting the `$inject` property
* is very inconvenient. In these situations using the array notation to specify the dependencies in
* a way that survives minification is a better choice:
*
* ```js
* // We wish to write this (not minification / obfuscation safe)
* injector.invoke(function($compile, $rootScope) {
* // ...
* });
*
* // We are forced to write break inlining
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
* // ...
* };
* tmpFn.$inject = ['$compile', '$rootScope'];
* injector.invoke(tmpFn);
*
* // To better support inline function the inline annotation is supported
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
* // ...
* }]);
*
* // Therefore
* expect(injector.annotate(
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
* ).toEqual(['$compile', '$rootScope']);
* ```
*
* @param {Function|Array.} fn Function for which dependent service names need to
* be retrieved as described above.
*
* @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
*
* @returns {Array.} The names of the services which the function requires.

* This method will add each of the injectables to the injector and execute all of the config and run

*
* * The application developer is responsible for loading the code containing the modules; and for
* ensuring that lazy scripts are not downloaded and executed more often that desired.
* * Previously compiled HTML will not be affected by newly loaded directives, filters and components.
* * Modules cannot be unloaded.
*
* You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded
* into the injector, which may indicate whether the script has been executed already.

* @description
*
* The {@link auto.$provide $provide} service has a number of methods for registering components
* with the {@link auto.$injector $injector}. Many of these functions are also exposed on
* {@link angular.Module}.
*
* An AngularJS **service** is a singleton object created by a **service factory**. These **service
* factories** are functions which, in turn, are created by a **service provider**.
* The **service providers** are constructor functions. When instantiated they must contain a
* property called `$get`, which holds the **service factory** function.
*
* When you request a service, the {@link auto.$injector $injector} is responsible for finding the
* correct **service provider**, instantiating it and then calling its `$get` **service factory**
* function to get the instance of the **service**.
*
* Often services have no configuration options and there is no need to add methods to the service
* provider. The provider will be no more than a constructor function with a `$get` property. For
* these cases the {@link auto.$provide $provide} service has additional helper methods to register
* services without specifying a provider.
*
* * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the

* * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate

/**
* @ngdoc method
* @name $provide#provider
* @description
*
* Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
* are constructor functions, whose instances are responsible for "providing" a factory for a
* service.
*
* Service provider names start with the name of the service they provide followed by `Provider`.
* For example, the {@link ng.$log $log} service has a provider called
* {@link ng.$logProvider $logProvider}.
*
* Service provider objects can have additional methods which allow configuration of the provider
* and its service. Importantly, you can configure what kind of service is created by the `$get`
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
* method {@link ng.$logProvider#debugEnabled debugEnabled}
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
* console or not.
*
* It is possible to inject other providers into the provider function,
* but the injected provider must have been defined before the one that requires it.
*
* @param {string} name The name of the instance. NOTE: the provider will be available under `name +
'Provider'` key.
* @param {(Object|function())} provider If the provider is:
*
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
* {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
* - `Constructor`: a new instance of the provider will be created using
* {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
*
* @returns {Object} registered provider instance
* @example
*
* The following example shows how to create a simple event tracking service and register it using
* {@link auto.$provide#provider $provide.provider()}.
*
* ```js
* // Define the eventTracker provider
* function EventTrackerProvider() {
* var trackingUrl = '/track';
*
* // A provider method for configuring where the tracked events should been saved
* this.setTrackingUrl = function(url) {
* trackingUrl = url;
* };
*
* // The service factory function
* this.$get = ['$http', function($http) {
* var trackedEvents = {};
* return {
* // Call this to track an event
* event: function(event) {
* var count = trackedEvents[event] || 0;
* count += 1;
* trackedEvents[event] = count;
* return count;

* in the
* [HTML5 spec](http://www.w3.org/html/wg/drafts/html/master/browsers.html#an-indicated-part-of-the-document).
*
* It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
* match any anchor whenever it changes. This can be disabled by calling
* {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
*
* Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
* vertical scroll-offset (either fixed or dynamic).
*
* @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
* {@link ng.$location#hash $location.hash()} will be used.
*
* @property {(number|function|jqLite)} yOffset
* If set, specifies a vertical scroll-offset. This is often useful when there are fixed
* positioned elements at the top of the page, such as navbars, headers etc.
*
* `yOffset` can be specified in various ways:
* - **number**: A fixed number of pixels to be used as offset.
* - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
* a number representing the offset (in pixels).
* - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
* the top of the page to the element's bottom will be used as offset.
* **Note**: The element will be taken into account only as long as its `position` is set to
* `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
* their height and/or positioning according to the viewport's size.
*
*
*
* In order for `yOffset` to work properly, scrolling should take place on the document's root and
* not some child element.
*

* @ngdoc method
* @name $animateProvider#customFilter
*
* @description
* Sets and/or returns the custom filter function that is used to "filter" animations, i.e.
* determine if an animation is allowed or not. When no filter is specified (the default), no
* animation will be blocked. Setting the `customFilter` value will only allow animations for
* which the filter function's return value is truthy.
*
* This allows to easily create arbitrarily complex rules for filtering animations, such as
* allowing specific events only, or enabling animations on specific subtrees of the DOM, etc.
* Filtering animations can also boost performance for low-powered devices, as well as
* applications containing a lot of structural operations.
*
*
* **Best Practice:**
* Keep the filtering function as lean as possible, because it will be called for each DOM
* action (e.g. insertion, removal, class change) performed by "animation-aware" directives.
* See {@link guide/animations#which-directives-support-animations- here} for a list of built-in
* directives that support animations.
* Performing computationally expensive or time-consuming operations on each call of the
* filtering function can make your animations sluggish.
*
*
* **Note:** If present, `customFilter` will be checked before
* {@link $animateProvider#classNameFilter classNameFilter}.
*
* @param {Function=} filterFn - The filter function which will be used to filter all animations.
* If a falsy value is returned, no animation will be performed. The function will be called
* with the following arguments:
* - **node** `{DOMElement}` - The DOM element to be animated.
* - **event** `{String}` - The name of the animation event (e.g. `enter`, `leave`, `addClass`

* - **options** `{Object}` - A collection of options/styles used for the animation.

* to ensure that animation runs with the triggered DOM operation.
*
* By default $animate doesn't trigger any animations. This is because the `ngAnimate` module isn't
* included and only when it is active then the animation hooks that `$animate` triggers will be
* functional. Once active then all structural `ng-` directives will trigger animations as they perform
* their DOM-related operations (enter, leave and move). Other directives such as `ngClass`,
* `ngShow`, `ngHide` and `ngMessages` also provide support for animations.
*
* It is recommended that the`$animate` service is always used when executing DOM-related procedures within directives.
*
* To learn more about enabling animation support, click here to visit the
* {@link ngAnimate ngAnimate module page}.

*
* ```js
* $animate.on('enter', container,
* function callback(element, phase) {
* // cool we detected an enter animation within the container
* }
* );
* ```
*
*
* **Note**: Generally, the events that are fired correspond 1:1 to `$animate` method names,
* e.g. {@link ng.$animate#addClass addClass()} will fire `addClass`, and {@link ng.ngClass}
* will fire `addClass` if classes are added, and `removeClass` if classes are removed.
* However, there are two exceptions:
*
*
*
if both an {@link ng.$animate#addClass addClass()} and a
* {@link ng.$animate#removeClass removeClass()} action are performed during the same
* animation, the event fired will be `setClass`. This is true even for `ngClass`.
*
an {@link ng.$animate#animate animate()} call that adds and removes classes will fire
* the `setClass` event, but if it either removes or adds classes,
* it will fire `animate` instead.
*
*
*
*
* @param {string} event the animation event that will be captured (e.g. enter, leave, move, addClass, removeClass, etc...)
* @param {DOMElement} container the container element that will capture each of the animation events that are fired on itself
* as well as among its children
* @param {Function} callback the callback function that will be fired when the listener is triggered.
*
* The arguments present in the callback function are:
* * `element` - The captured DOM element that the animation was fired on.
* * `phase` - The phase of the animation. The two possible phases are **start** (when the animation starts) and **close** (when it ends).
* * `data` - an object with these properties:
* * addClass - `{string|null}` - space-separated CSS classes to add to the element
* * removeClass - `{string|null}` - space-separated CSS classes to remove from the element
* * from - `{Object|null}` - CSS properties & values at the beginning of the animation
* * to - `{Object|null}` - CSS properties & values at the end of the animation
*
* Note that the callback does not trigger a scope digest. Wrap your call into a
* {@link $rootScope.Scope#$apply scope.$apply} to propagate changes to the scope.

/**
* @ngdoc service
* @name $compile
* @kind function
*
* @description
* Compiles an HTML string or DOM into a template and produces a template function, which
* can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
*
* The compilation is a process of walking the DOM tree and matching DOM elements to
* {@link ng.$compileProvider#directive directives}.
*
*
* **Note:** This document is an in-depth reference of all directive options.
* For a gentle introduction to directives with examples of common use cases,
* see the {@link guide/directive directive guide}.
*
*
* ## Comprehensive Directive API
*
* There are many different options for a directive.
*
* The difference resides in the return value of the factory function.
* You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
* that defines the directive properties, or just the `postLink` function (all other properties will have
* the default values).
*
*
* **Best Practice:** It's recommended to use the "directive definition object" form.
*
* **Note:** Any unspecified options will use the default value. You can see the default values below.
*
*
* Therefore the above can be simplified as:
*
* ```js
* var myModule = angular.module(...);
*
* myModule.directive('directiveName', function factory(injectables) {
* var directiveDefinitionObject = {
* link: function postLink(scope, iElement, iAttrs) { ... }
* };
* return directiveDefinitionObject;
* // or
* // return function postLink(scope, iElement, iAttrs) { ... }
* });
* ```
*
* ### Life-cycle hooks
* Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the
* directive:
* * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
* had their bindings initialized (and before the pre & post linking functions for the directives on
* this element). This is a good place to put initialization code for your controller.
* * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
* `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
* object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
* component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
* also be called when your bindings are initialized.
* * `$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 `$onChanges` is called. For example, this hook
* could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
* be detected by AngularJS's change detector and thus not trigger `$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 life-cycle hooks in the new Angular
* The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are
* some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:
*
* * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.
* * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.
* In Angular 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 `$doCheck` in AngularJS than you would to
* `ngDoCheck` in Angular.
* * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
* propagated throughout the application.
* Angular 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.
*
*
*
* angular.module('do-check-module', [])
* .component('app', {
* template:
* 'Month: ' +
* 'Date: {{ $ctrl.date }}' +
* '',
* controller: function() {
* this.date = new Date();
* this.month = this.date.getMonth();
* this.updateDate = function() {
* this.date.setMonth(this.month);
* };
* }
* })
* .component('test', {
* bindings: { date: '<' },
* template:
* '
{{ $ctrl.log | json }}
',
* controller: function() {
* var previousValue;
* this.log = [];
* this.$doCheck = function() {
* var currentValue = this.date && this.date.valueOf();
* if (previousValue !== currentValue) {
* this.log.push('doCheck: date mutated: ' + this.date);
* previousValue = currentValue;
* }
* };
* }
* });
*
*
*
*
*
*
* This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
* actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
* arrays or objects can have a negative impact on your application performance.)
*
*
*
*
',
* controller: function() {
* this.log = [];
*
* this.$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);
* }
* };
* }
* });
*
*
*
*
* ### 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 template.
* 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. Note that an isolate scope
* directive without a `template` or `templateUrl` will not apply the isolate scope
* to its children elements.
*
* 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 `` 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 `` 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. 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
* `$watchCollection`}: use `=*` or `=*attr`
*
* * `<` or `` and directive definition of
* `scope: { localModel:'` and the isolate scope definition `scope: {
* localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
* the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
* via an expression to the parent scope. This can be done by passing a map of local variable names
* and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
* then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
*
* All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.
* The marker must come after the mode and before the attribute name.
* See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.
* This is useful to refine the interface directives provide.
* One subtle difference between optional and non-optional happens **when the binding attribute is not
* set**:
* - the binding is optional: the property will not be defined
* - the binding is not optional: the property is defined
*
* ```js
*app.directive('testDir', function() {
return {
scope: {
notoptional: '=',
optional: '=?',
},
bindToController: true,
controller: function() {
this.$onInit = function() {
console.log(this.hasOwnProperty('notoptional')) // true
console.log(this.hasOwnProperty('optional')) // false
}
}
}
})
*```
*
*
* ##### Combining directives with different scope defintions
*
* In general it's possible to apply more than one directive to one element, but there might be limitations
* depending on the type of scope required by the directives. The following points will help explain these limitations.
* For simplicity only two directives are taken into account, but it is also applicable for several directives:
*
* * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
* * **child scope** + **no scope** => Both directives will share one single child scope
* * **child scope** + **child scope** => Both directives will share one single child scope
* * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use
* its parent's scope
* * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
* be applied to the same element.
* * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives
* cannot be applied to the same element.
*
*
* #### `bindToController`
* This property is used to bind scope properties directly to the controller. It can be either
* `true` or an object hash with the same format as the `scope` property.
*
* When an isolate scope is used for a directive (see above), `bindToController: true` will
* allow a component to have its properties bound to the controller, rather than to scope.
*
* After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
* properties. You can access these bindings once they have been initialized by providing a controller method called
* `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
* initialized.
*
* 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 `
