Methods

  • deferIntercept(defer?: boolean): void
  • Disables monitoring of the URL.

  • Disables monitoring of the URL.

    Call this method before UI-Router has bootstrapped. It will stop UI-Router from performing the initial url sync.

    This can be useful to perform some asynchronous initialization before the router starts. Once the initialization is complete, call listen to tell UI-Router to start watching and synchronizing the URL.

    Example:

    // Prevent UI-Router from automatically intercepting URL changes when it starts;
    urlService.deferIntercept();
    
    fetch('/states.json').then(resp => resp.json()).then(data => {
      data.forEach(state => $stateRegistry.register(state));
      urlService.listen();
      urlService.sync();
    });

    Parameters

    • defer: Optional  boolean
      :

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

    Returns void


  • hash(): string
  • Gets the hash part of the current url

  • Gets the hash part of the current url

    If the current URL is /some/path?query=value#anchor, this returns anchor

    Returns string

    :

    the hash (anchor) portion of the url


  • listen(enabled?: boolean): Function
  • Starts or stops listening for URL changes

  • Starts or stops listening for URL changes

    Call this sometime after calling deferIntercept to start monitoring the url. This causes UI-Router to start listening for changes to the URL, if it wasn't already listening.

    If called with false, UI-Router will stop listening (call listen(true) to start listening again).

    Example:

    urlService.deferIntercept();
    
    fetch('/states.json').then(resp => resp.json()).then(data => {
      data.forEach(state => $stateRegistry.register(state));
      // Start responding to URL changes
      urlService.listen();
      urlService.sync();
    });

    Parameters

    • enabled: Optional  boolean
      :

      true or false to start or stop listening to URL changes

    Returns Function


  • Matches a URL

    Given a URL (as a UrlParts object), check all rules and determine the best matching rule. Return the result as a MatchResult.

    Parameters

    Returns MatchResult


  • onChange(callback: EventListener): Function
  • Parameters

    • callback EventListener
      :

      a function that will be called when the url is changing

    Returns Function

    :

    a function that de-registers the callback


  • parts(): UrlParts
  • Gets the current URL parts

  • Gets the current URL parts

    This method returns the different parts of the current URL (the path, search, and hash) as a UrlParts object.

    Returns UrlParts


  • path(): string
  • Gets the path part of the current url

  • Gets the path part of the current url

    If the current URL is /some/path?query=value#anchor, this returns /some/path

    Returns string

    :

    the path portion of the url


  • search(): object
  • Gets the search part of the current url as an object

  • Gets the search part of the current url as an object

    If the current URL is /some/path?query=value#anchor, this returns { query: 'value' }

    Returns object

    :

    the search (query) portion of the url, as an object

    • [key: string]: any

  • sync(evt?: any): void
  • Activates the best rule for the current URL

  • Activates the best rule for the current URL

    Checks the current URL for a matching UrlRule, then invokes that rule's handler. This method is called internally any time the URL has changed.

    This effectively activates the state (or redirect, etc) which matches the current URL.

    Example:

    urlService.deferIntercept();
    
    fetch('/states.json').then(resp => resp.json()).then(data => {
      data.forEach(state => $stateRegistry.register(state));
      urlService.listen();
      // Find the matching URL and invoke the handler.
      urlService.sync();
    });

    Parameters

    • evt: Optional  any

    Returns void


  • url(newurl?: string, replace?: boolean, state?: any): string
  • Gets the current url, or updates the url

  • Gets the current url, or updates the url

    Getting the current URL

    When no arguments are passed, returns the current URL. The URL is normalized using the internal path/search/hash values.

    For example, the URL may be stored in the hash ([[HashLocationServices]]) or have a base HREF prepended ([[PushStateLocationServices]]).

    The raw URL in the browser might be:

    http://mysite.com/somepath/index.html#/internal/path/123?param1=foo#anchor

    or

    http://mysite.com/basepath/internal/path/123?param1=foo#anchor

    then this method returns:

    /internal/path/123?param1=foo#anchor

    Example:

    locationServices.url(); // "/some/path?query=value#anchor"

    Updating the URL

    When newurl arguments is provided, changes the URL to reflect newurl

    Example:

    locationServices.url("/some/path?query=value#anchor", true);

    Parameters

    • newurl: Optional  string
      :

      The new value for the URL. This url should reflect only the new internal path, search, and hash values. It should not include the protocol, site, port, or base path of an absolute HREF.

    • replace: Optional  boolean
      :

      When true, replaces the current history entry (instead of appending it) with this new url

    • state: Optional  any
      :

      The history's state object, i.e., pushState (if the LocationServices implementation supports it)

    Returns string

    :

    the url (after potentially being processed)
