* @description
|
|
* The new `$stateProvider` works similar to Angular's v1 router, but it focuses purely
|
|
* on state.
|
|
*
|
|
* A state corresponds to a "place" in the application in terms of the overall UI and
|
|
* navigation. A state describes (via the controller / template / view properties) what
|
|
* the UI looks like and does at that place.
|
|
*
|
|
* States often have things in common, and the primary way of factoring out these
|
|
* commonalities in this model is via the state hierarchy, i.e. parent/child states aka
|
|
* nested states.
|
|
*
|
|
* The `$stateProvider` provides interfaces to declare these states for your app.

* @ngdoc function
|
|
* @name ui.router.state.$stateProvider#decorator
|
|
* @methodOf ui.router.state.$stateProvider
|
|
*
|
|
* @description
|
|
* Allows you to extend (carefully) or override (at your own peril) the
|
|
* `stateBuilder` object used internally by `$stateProvider`. This can be used
|
|
* to add custom functionality to ui-router, for example inferring templateUrl
|
|
* based on the state name.
|
|
*
|
|
* When passing only a name, it returns the current (original or decorated) builder
|
|
* function that matches `name`.
|
|
*
|
|
* The builder functions that can be decorated are listed below. Though not all
|
|
* necessarily have a good use case for decoration, that is up to you to decide.
|
|
*
|
|
* In addition, users can attach custom decorators, which will generate new
|
|
* properties within the state's internal definition. There is currently no clear
|
|
* use-case for this beyond accessing internal states (i.e. $state.$current),
|
|
* however, expect this to become increasingly relevant as we introduce additional
|
|
* meta-programming features.
|
|
*
|
|
* **Warning**: Decorators should not be interdependent because the order of
|
|
* execution of the builder functions in non-deterministic. Builder functions
|
|
* should only be dependent on the state definition object and super function.
|
|
*
|
|
*
|
|
* Existing builder functions and current return values:
|
|
*
|
|
* - **parent** `{object}` - returns the parent state object.
|
|
* - **data** `{object}` - returns state data, including any inherited data that is not
|
|
* overridden by own values (if any).
|
|
* - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
|
|
* or `null`.
|
|
* - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is
|
|
* navigable).
|
|
* - **params** `{object}` - returns an array of state params that are ensured to
|
|
* be a super-set of parent's params.
|
|
* - **views** `{object}` - returns a views object where each key is an absolute view
|
|
* name (i.e. "viewName@stateName") and each value is the config object
|
|
* (template, controller) for the view. Even when you don't use the views object
|
|
* explicitly on a state config, one is still created for you internally.
|
|
* So by decorating this builder function you have access to decorating template
|
|
* and controller properties.
|
|
* - **ownParams** `{object}` - returns an array of params that belong to the state,
|
|
* not including any params defined by ancestor states.
|
|
* - **path** `{string}` - returns the full path from the root down to this state.
|
|
* Needed for state activation.
|
|
* - **includes** `{object}` - returns an object that includes every state that
|
|
* would pass a `$state.includes()` test.
|
|
*
|
|
* @example
|
|
* <pre>
|
|
* // Override the internal 'views' builder with a function that takes the state
|
|
* // definition, and a reference to the internal function being overridden:
|
|
* $stateProvider.decorator('views', function (state, parent) {
|
|
* var result = {},
|
|
* views = parent(state);
|
|
*
|
|
* angular.forEach(views, function (config, name) {
|
|
* var autoName = (state.name + '.' + name).replace('.', '/');
|
|
* config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
|
|
* result[name] = config;
|
|
* });
|
|
* return result;
|
|
* });
|
|
*
|
|
* $stateProvider.state('home', {
|
|
* views: {
|
|
* 'contact.list': { controller: 'ListController' },
|
|
* 'contact.item': { controller: 'ItemController' }
|
|
* }
|
|
* });
|
|
*
|
|
* // ...
|

* $state.go('home');
|
|
* // Auto-populates list and item views with /partials/home/contact/list.html,
|
|
* // and /partials/home/contact/item.html, respectively.

|
|

|
|
*
|
|
* Examples:
|
|
*
|
|
* Targets three named `ui-view`s in the parent state's template
|
|
* <pre>views: {
|
|
* header: {
|
|
* controller: "headerCtrl",
|
|
* templateUrl: "header.html"
|
|
* }, body: {
|
|
* controller: "bodyCtrl",
|
|
* templateUrl: "body.html"
|
|
* }, footer: {
|
|
* controller: "footCtrl",
|
|
* templateUrl: "footer.html"
|
|
* }
|
|
* }</pre>
|
|
*
|
|
* Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
|
|
* <pre>views: {
|
|
* 'header@top': {
|
|
* controller: "msgHeaderCtrl",
|
|
* templateUrl: "msgHeader.html"
|
|
* }, 'body': {
|
|
* controller: "messagesCtrl",
|
|
* templateUrl: "messages.html"
|
|
* }
|
|
* }</pre>
|
|
*
|
|
* @param {boolean=} [stateConfig.abstract=false]
|
|
* <a id='abstract'></a>
|
|
* An abstract state will never be directly activated,
|
|
* but can provide inherited properties to its common children states.
|
|
* <pre>abstract: true</pre>
|
|
*
|
|
* @param {function=} stateConfig.onEnter
|
|
* <a id='onEnter'></a>
|
|
*
|
|
* Callback function for when a state is entered. Good way
|
|
* to trigger an action or dispatch an event, such as opening a dialog.
|
|
* If minifying your scripts, make sure to explictly annotate this function,
|
|
* because it won't be automatically annotated by your build tools.
|
|
*
|
|
* <pre>onEnter: function(MyService, $stateParams) {
|
|
* MyService.foo($stateParams.myParam);
|
|
* }</pre>
|
|
*
|
|
* @param {function=} stateConfig.onExit
|

|
|
*

* trigger an action or dispatch an event, such as opening a dialog.
|
|
* If minifying your scripts, make sure to explictly annotate this function,
|
|
* because it won't be automatically annotated by your build tools.
|
|
*
|
|
* <pre>onExit: function(MyService, $stateParams) {
|
|
* MyService.cleanup($stateParams.myParam);
|
|
* }</pre>
|
|
*
|
|
* @param {boolean=} [stateConfig.reloadOnSearch=true]
|
|
* <a id='reloadOnSearch'></a>
|
|
*
|
|
* If `false`, will not retrigger the same state
|
|
* just because a search/query parameter has changed (via $location.search() or $location.hash()).
|
|
* Useful for when you'd like to modify $location.search() without triggering a reload.
|
|
* <pre>reloadOnSearch: false</pre>
|
|
*
|
|
* @param {object=} stateConfig.data
|
|
* <a id='data'></a>
|
|
*
|
|
* Arbitrary data object, useful for custom configuration. The parent state's `data` is
|
|
* prototypally inherited. In other words, adding a data property to a state adds it to
|
|
* the entire subtree via prototypal inheritance.
|
|
*
|
|
* <pre>data: {
|
|
* requiredRole: 'foo'
|
|
* } </pre>
|
|
*
|
|
* @param {object=} stateConfig.params
|
|
* <a id='params'></a>
|
|
*
|
|
* A map which optionally configures parameters declared in the `url`, or
|
|
* defines additional non-url parameters. For each parameter being
|
|
* configured, add a configuration object keyed to the name of the parameter.
|
|
*
|
|
* Each parameter configuration object may contain the following properties:
|
|
*
|
|
* - ** value ** - {object|function=}: specifies the default value for this
|
|
* parameter. This implicitly sets this parameter as optional.
|
|
*
|
|
* When UI-Router routes to a state and no value is
|
|
* specified for this parameter in the URL or transition, the
|
|
* default value will be used instead. If `value` is a function,
|
|
* it will be injected and invoked, and the return value used.
|
|
*
|
|
* *Note*: `undefined` is treated as "no default value" while `null`
|
|
* is treated as "the default value is `null`".
|
|
*
|
|
* *Shorthand*: If you only need to configure the default value of the
|
|
* parameter, you may use a shorthand syntax. In the **`params`**
|
|
* map, instead mapping the param name to a full parameter configuration
|
|
* object, simply set map it to the default parameter value, e.g.:
|
|
*
|
|
* <pre>// define a parameter's default value
|
|
* params: {
|
|
* param1: { value: "defaultValue" }
|
|
* }
|
|
* // shorthand default values
|
|
* params: {
|
|
* param1: "defaultValue",
|
|
* param2: "param2Default"
|
|
* }</pre>
|
|
*
|
|
* - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
|
|
* treated as an array of values. If you specified a Type, the value will be
|
|
* treated as an array of the specified Type. Note: query parameter values
|
|
* default to a special `"auto"` mode.
|
|
*
|
|
* For query parameters in `"auto"` mode, if multiple values for a single parameter
|
|
* are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
|
|
* are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`). However, if
|
|
* only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
|
|
* value (e.g.: `{ foo: '1' }`).
|
|
*
|
|
* <pre>params: {
|
|
* param1: { array: true }
|
|
* }</pre>
|
|
*
|
|
* - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
|
|
* the current parameter value is the same as the default value. If `squash` is not set, it uses the
|
|
* configured default squash policy.
|
|
* (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
|
|
*
|
|
* There are three squash settings:
|
|
*
|
|
* - false: The parameter's default value is not squashed. It is encoded and included in the URL
|
|
* - true: The parameter's default value is omitted from the URL. If the parameter is preceeded and followed
|
|
* by slashes in the state's `url` declaration, then one of those slashes are omitted.
|
|
* This can allow for cleaner looking URLs.
|
|
* - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of your choice.
|
|
*
|
|
* <pre>params: {
|
|
* param1: {
|
|
* value: "defaultId",
|
|
* squash: true
|
|
* } }
|
|
* // squash "defaultValue" to "~"
|
|
* params: {
|
|
* param1: {
|
|
* value: "defaultValue",
|
|
* squash: "~"
|
|
* } }
|
|
* </pre>
|
|
*
|
|
*
|
|
* @example
|
|
* <pre>
|
|
* // Some state name examples
|
|
*
|
|
* // stateName can be a single top-level name (must be unique).

|
* @description
|
|
* Convenience method for transitioning to a new state. `$state.go` calls
|
|
* `$state.transitionTo` internally but automatically sets options to
|
|
* `{ location: true, inherit: true, relative: $state.$current, notify: true }`.
|
|
* This allows you to easily use an absolute or relative to path and specify
|
|
* only the parameters you'd like to update (while letting unspecified parameters
|
|
* inherit from the currently active ancestor states).
|
|
*
|
|
* @example
|
|
* <pre>
|
|
* var app = angular.module('app', ['ui.router']);
|
|
*
|

* @param {string} to Absolute state name or relative state path. Some examples:
|
|
*
|
|
* - `$state.go('contact.detail')` - will go to the `contact.detail` state
|
|
* - `$state.go('^')` - will go to a parent state
|
|
* - `$state.go('^.sibling')` - will go to a sibling state
|
|
* - `$state.go('.child.grandchild')` - will go to grandchild state
|
|
*
|
|
* @param {object=} params A map of the parameters that will be sent to the state,
|
|
* will populate $stateParams. Any parameters that are not specified will be inherited from currently
|
|
* defined parameters. This allows, for example, going to a sibling state that shares parameters
|
|
* specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
|
|
* transitioning to a sibling will get you the parameters for all parents, transitioning to a child
|
|
* will get you all current parameters, etc.
|
|
* @param {object=} options Options object. The options are:
|
|
*
|
|
* - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
|
|
* will not. If string, must be `"replace"`, which will update url and also replace last history record.
|
|
* - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
|
|
* - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'),
|
|
* defines which state to be relative from.
|
|
* - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
|
|
* - **`reload`** (v0.2.5) - {boolean=false}, If `true` will force transition even if the state or params
|
|
* have not changed, aka a reload of the same state. It differs from reloadOnSearch because you'd
|
|
* use this when you want to force a reload when *everything* is the same, including search params.
|
|
*
|
|
* @returns {promise} A promise representing the state of the new transition.
|
|
*
|
|
* Possible success values:
|
|
*
|
|
* - $state.current
|
|
*
|
|
* <br/>Possible rejection values:
|
|
*
|
|
* - 'transition superseded' - when a newer transition has been started after this one
|
|
* - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
|
|
* - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
|
|
* when a `$stateNotFound` `event.retry` promise errors.
|
|
* - 'transition failed' - when a state has been unsuccessfully found after 2 tries.
