Methods

  • _handleInvalidTargetState(fromPath: PathNode[], toState: TargetState): any
  • Handler for when transitionTo is called with an invalid state.

  • Handler for when transitionTo is called with an invalid state.

    Invokes the onInvalid callbacks, in natural order. Each callback's return value is checked in sequence until one of them returns an instance of TargetState. The results of the callbacks are wrapped in $q.when(), so the callbacks may return promises.

    If a callback returns an TargetState, then it is used as arguments to $state.transitionTo() and the result returned.

    Parameters

    Returns any


  • defaultErrorHandler(handler?: function): function
  • Sets or gets the default transitionTo error handler.

  • Sets or gets the default transitionTo error handler.

    The error handler is called when a Transition is rejected or when any error occurred during the Transition. This includes errors caused by resolves and transition hooks.

    Note: This handler does not receive certain Transition rejections. Redirected and Ignored Transitions are not considered to be errors by StateService.transitionTo.

    The built-in default error handler logs the error to the console.

    You can provide your own custom handler.

    Example:

    stateService.defaultErrorHandler(function() {
      // Do not log transitionTo errors
    });
    

    Parameters

    • handler: Optional  function
      :

      a global error handler function

        • (error: any): void
        • Parameters

          • error any

          Returns void

    Returns function

    :

    the current global error handler

      • (error: any): void
      • Parameters

        • error any

        Returns void


  • dispose(): void
  • getCurrentPath(): PathNode[]
  • Transition to a different state and/or parameters

    Convenience method for transitioning to a new state.

    $state.go calls $state.transitionTo internally but automatically sets options to { location: true, inherit: true, relative: router.globals.$current, notify: true }. This allows you to use either an absolute or relative to argument (because of relative: router.globals.$current). It also allows you to specify * only the parameters you'd like to update, while letting unspecified parameters inherit from the current parameter values (because of inherit: true).

    Example:

    let app = angular.module('app', ['ui.router']);
    
    app.controller('ctrl', function ($scope, $state) {
      $scope.changeState = function () {
        $state.go('contact.detail');
      };
    });
    

    Some examples:

    • $state.go('contact.detail') - will go to the contact.detail state
    • $state.go('^') - will go to the parent state
    • $state.go('^.sibling') - if current state is home.child, will go to the home.sibling state
    • $state.go('.child.grandchild') - if current state is home, will go to the home.child.grandchild state

    Any parameters that are not specified will be inherited from current parameter values (because of inherit: true). This allows, for example, going to a sibling state that shares parameters defined by a parent state.

    Parameters

    • to StateOrName
      :

      Absolute state name, state object, or relative state path (relative to current state).

    • params: Optional  RawParams
      :

      A map of the parameters that will be sent to the state, will populate $stateParams.

    • options: Optional  TransitionOptions
      :

      Transition options

    Returns TransitionPromise

    :

    A promise representing the state of the new transition.


  • Generates a URL for a state and parameters

    Returns the url for the given state populated with the given params.

    Example:

    expect($state.href("about.person", { person: "bob" })).toEqual("/about/bob");
    

    Parameters

    • stateOrName StateOrName
      :

      The state name or state object you'd like to generate a url from.

    • params RawParams
      :

      An object of parameter values to fill the state's required parameters.

    • options: Optional  HrefOptions
      :

      Options object. The options are:

    Returns string

    :

    compiled state url


  • Checks if the current state includes the provided state

    A method to determine if the current active state is equal to or is the child of the state stateName. If any params are passed then they will be tested for a match as well. Not all the parameters need to be passed, just the ones you'd like to test for equality.

    Example when $state.$current.name === 'contacts.details.item'

    // Using partial names
    $state.includes("contacts"); // returns true
    $state.includes("contacts.details"); // returns true
    $state.includes("contacts.details.item"); // returns true
    $state.includes("contacts.list"); // returns false
    $state.includes("about"); // returns false
    

    Glob Examples when * $state.$current.name === 'contacts.details.item.url':

    $state.includes("*.details.*.*"); // returns true
    $state.includes("*.details.**"); // returns true
    $state.includes("**.item.**"); // returns true
    $state.includes("*.details.item.url"); // returns true
    $state.includes("*.details.*.url"); // returns true
    $state.includes("*.details.*"); // returns false
    $state.includes("item.**"); // returns false
    

    or state object to be searched for within the current state name. that you'd like to test against the current active state.

    • relative: If stateOrName is a relative state name and options.relative is set, .is will test relative to options.relative state (or name).

    Parameters

    • stateOrName StateOrName
      :

      A partial name, relative name, glob pattern,

    • params: Optional  RawParams
      :

      A param object, e.g. {sectionId: section.id},

    • options: Optional  TransitionOptions
      :

      An options object. The options are:

    Returns boolean

    :

    Returns true if it does include the state


  • is(stateOrName: StateOrName, params?: RawParams, options?: object): boolean
  • Checks if the current state is the provided state

  • Checks if the current state is the provided state

    Similar to includes but only checks for the full state name. If params is supplied then it will be tested for strict equality against the current active params object, so all params must match with none missing and no extras.

    Example:

    $state.$current.name = 'contacts.details.item';
    
    // absolute name
    $state.is('contact.details.item'); // returns true
    $state.is(contactDetailItemStateObject); // returns true
    

    // relative name (. and ^), typically from a template // E.g. from the 'contacts.details' template

    <div ng-class="{highlighted: $state.is('.item')}">Item</div>
    

    to test against the current active state.

    • relative: If stateOrName is a relative state name and options.relative is set, .is will test relative to options.relative state (or name).

    Parameters

    • stateOrName StateOrName
      :

      The state name (absolute or relative) or state object you'd like to check.

    • params: Optional  RawParams
      :

      A param object, e.g. {sectionId: section.id}, that you'd like

    • options: Optional  object
      :

      An options object. The options are:

    Returns boolean

    :

    Returns true if it is the state.


  • Lazy loads a state

    Explicitly runs a state's StateDeclaration.lazyLoad function.

    Note: If no transition is provided, a noop transition is created using the from the current state to the current state. This noop transition is not actually run.

    Parameters

    • stateOrName StateOrName
      :

      the state that should be lazy loaded

    • transition: Optional  Transition
      :

      the optional Transition context to use (if the lazyLoad function requires an injector, etc)

    Returns Promise<LazyLoadResult>

    :

    a promise to lazy load


  • onInvalid(callback: OnInvalidCallback): Function
  • Registers an Invalid State handler

  • Registers an Invalid State handler

    Registers a OnInvalidCallback function to be invoked when StateService.transitionTo has been called with an invalid state reference parameter

    Example:

    stateService.onInvalid(function(to, from, injector) {
      if (to.name() === 'foo') {
        let lazyLoader = injector.get('LazyLoadService');
        return lazyLoader.load('foo')
            .then(() => stateService.target('foo'));
      }
    });
    

    This function receives the (invalid) toState, the fromState, and an injector. The function may optionally return a TargetState or a Promise for a TargetState. If one is returned, it is treated as a redirect.

    Parameters

    Returns Function

    :

    a function which deregisters the callback


  • Reloads the current state

    A method that force reloads the current state, or a partial state hierarchy. All resolves are re-resolved, and components reinstantiated.

    Example:

    let app angular.module('app', ['ui.router']);
    
    app.controller('ctrl', function ($scope, $state) {
      $scope.reload = function(){
        $state.reload();
      }
    });
    

    Note: reload() is just an alias for:

    $state.transitionTo($state.current, $state.params, {
      reload: true, inherit: false
    });
    

    If present, this state and all its children will be reloaded, but ancestors will not reload.

    Example:

    //assuming app application consists of 3 states: 'contacts', 'contacts.detail', 'contacts.detail.item'
    //and current state is 'contacts.detail.item'
    let app angular.module('app', ['ui.router']);
    
    app.controller('ctrl', function ($scope, $state) {
      $scope.reload = function(){
        //will reload 'contact.detail' and nested 'contact.detail.item' states
        $state.reload('contact.detail');
      }
    });
    

    Parameters

    • reloadState: Optional  StateOrName
      :

      A state name or a state object.

    Returns Promise<StateObject>

    :

    A promise representing the state of the new transition. See StateService.go


  • Low-level method for transitioning to a new state.

    The go method (which uses transitionTo internally) is recommended in most situations.

    Example:

    let app = angular.module('app', ['ui.router']);
    
    app.controller('ctrl', function ($scope, $state) {
      $scope.changeState = function () {
        $state.transitionTo('contact.detail');
      };
    });
    
     will populate $stateParams.
    

    Parameters

    • to StateOrName
      :

      State name or state object.

    • toParams: Default value  RawParams = {}
      :

      A map of the parameters that will be sent to the state,

    • options: Default value  TransitionOptions = {}
      :

      Transition options

    Returns TransitionPromise

    :

    A promise representing the state of the new transition. See go
