  1. $locationProvider
  2. service in module ng

Overview

The $location service parses the URL in the browser address bar (based on the window.location) and makes the URL available to your application. Changes to the URL in the address bar are reflected into $location service and changes to $location are reflected into the browser address bar.

The $location service:

  • Exposes the current URL in the browser address bar, so you can
    • Watch and observe the URL.
    • Change the URL.
  • Synchronizes the URL with the browser when the user
    • Changes the address bar.
    • Clicks the back or forward button (or clicks a History link).
    • Clicks on a link.
  • Represents the URL object as a set of methods (protocol, host, port, path, search, hash).

    Parameters

    Param Type Details
    search stringObject.<string>Object.<Array.<string>>

    New search params - string or hash object.

    When called with a single argument the method acts as a setter, setting the search component of $location to the specified value.

    If the argument is a hash object containing an array of values, these values will be encoded as duplicate search parameters in the URL.
    paramValue
    (optional)
    		 stringNumberArray.<string>boolean

    If search is a string or number, then paramValue will override only a single search property.

    If paramValue is an array, it will override the property of the search component of $location specified via the first argument.

    If paramValue is null, the property specified via the first argument will be deleted.

    If paramValue is true, the property specified via the first argument will be added with no value nor trailing equal sign.

    Returns

    Object

    If called with no arguments returns the parsed search object. If called with one or more arguments returns $location object itself.

    State object for pushState or replaceState
