$locationProvider

description

$urlRouterProvider has the responsibility of watching $location. When $location changes it runs through a list of rules one by one until a match is found. $urlRouterProvider is used behind the scenes anytime you specify a url in a state configuration. All urls are compiled into a UrlMatcher object.

There are several methods on $urlRouterProvider that make it useful to use directly in your module config.

    function

    name

    ui.router.router.$urlRouterProvider#deferIntercept

    methodof

    ui.router.router.$urlRouterProvider

    description

    Disables (or enables) deferring location change interception.

    If you wish to customize the behavior of syncing the URL (for example, if you wish to defer a transition but maintain the current URL), call this method at configuration time. Then, at run time, call $urlRouter.listen() after you have configured your own $locationChangeSuccess event handler.

    example
    var app = angular.module('app', ['ui.router.router']);
    
    app.config(function ($urlRouterProvider) {
    
      // Prevent $urlRouter from automatically intercepting URL changes;
      // this allows you to configure custom behavior in between
      // location changes and route synchronization:
      $urlRouterProvider.deferIntercept();
    
    }).run(function ($rootScope, $urlRouter, UserService) {
    
      $rootScope.$on('$locationChangeSuccess', function(e) {
        // UserService is an example service for managing user state
        if (UserService.isLoggedIn()) return;
    
        // Prevent $urlRouter's default handler from firing
        e.preventDefault();
    
        UserService.handleLogin().then(function() {
          // Once the user has logged in, sync the current URL
          // to the router:
          $urlRouter.sync();
        });
      });
    
      // Configures $urlRouter's listener *after* your custom listener
      $urlRouter.listen();
    });
    

    Parameters

    • defer: any
      :

      Indicates whether to defer location change interception. Passing no parameter is equivalent to true.

    Returns void

    name

    ui.router.router.$urlRouterProvider#otherwise

    methodof

    ui.router.router.$urlRouterProvider

    description

    Defines a path that is used when an invalid route is requested.

    example
    var app = angular.module('app', ['ui.router.router']);
    
    app.config(function ($urlRouterProvider) {
      // if the path doesn't match any of the urls you configured
      // otherwise will take care of routing the user to the
      // specified url
      $urlRouterProvider.otherwise('/index');
    
      // Example of using function rule as param
      $urlRouterProvider.otherwise(function ($injector, $location) {
        return '/a/valid/url';
      });
    });
    

    Parameters

    • rule: any
      :

      The url path you want to redirect to or a function rule that returns the url path. The function version is passed two params: $injector and $location services, and must return a url string.

    Returns UrlRouterProvider

    :

    $urlRouterProvider - $urlRouterProvider instance

    function

    name

    ui.router.router.$urlRouterProvider#rule

    methodof

    ui.router.router.$urlRouterProvider

    description

    Defines rules that are used by $urlRouterProvider to find matches for specific URLs.

    example
    var app = angular.module('app', ['ui.router.router']);
    
    app.config(function ($urlRouterProvider) {
      // Here's an example of how you might allow case insensitive urls
      $urlRouterProvider.rule(function ($injector, $location) {
        var path = $location.path(),
            normalized = path.toLowerCase();
    
        if (path !== normalized) {
          return normalized;
        }
      });
    });
    

    Parameters

    • rule: any
      :

      Handler function that takes $injector and $location services as arguments. You can use them to return a valid path as a string.

    Returns UrlRouterProvider

    :

    $urlRouterProvider - $urlRouterProvider instance

    function

    name

    ui.router.router.$urlRouterProvider#when

    methodof

    ui.router.router.$urlRouterProvider

    description

    Registers a handler for a given url matching.

    If the handler is a string, it is treated as a redirect, and is interpolated according to the syntax of match (i.e. like String.replace() for RegExp, or like a UrlMatcher pattern otherwise).

    If the handler is a function, it is injectable. It gets invoked if $location matches. You have the option of inject the match object as $match.

    The handler can return

    • falsy to indicate that the rule didn't match after all, then $urlRouter will continue trying to find another one that matches.
    • string which is treated as a redirect and passed to $location.url()
    • void or any truthy value tells $urlRouter that the url was handled.
    example
    var app = angular.module('app', ['ui.router.router']);
    
    app.config(function ($urlRouterProvider) {
      $urlRouterProvider.when($state.url, function ($match, $stateParams) {
        if ($state.$current.navigable !== state ||
            !equalForKeys($match, $stateParams) {
         $state.transitionTo(state, $match, false);
        }
      });
    });
    

    Parameters

    • what: any
      :

      The incoming path that you want to redirect.

    • handler: any
      :

      The path you want to redirect your user to.
