$locationProvider
service in module ng

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

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.

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.

hash([hash]);
This method is getter / setter.

Returns the hash fragment when called without any parameters.

Changes the hash fragment when called with a parameter and returns $location.
```
// given url http://example.com/#/some/path?foo=bar&baz=xoxo#hashValue
var hash = $location.hash();
// => "hashValue"
```
Parameters

Param Type Details

hash
(optional)
stringnumber
New hash fragment

Returns

string
hash
replace();

If called, all changes to $location during the current $digest will replace the current history record, instead of adding a new one.
state([state]);

This method is getter / setter.

Return the history state object when called without any parameter.

Change the history state object when called with one parameter and return $location. The state object is later passed to pushState or replaceState.

NOTE: This method is supported only in HTML5 mode and only in browsers supporting the HTML5 History API (i.e. methods pushState and replaceState). If you need to support older browsers (like IE9 or Android < 4.0), don't use this method.

Parameters

Param Type Details

state
(optional)
object
State object for pushState or replaceState

Returns

object
state

Param	Type	Details
hash (optional)	`stringnumber`	New hash fragment

Param	Type	Details
state (optional)	`object`	State object for pushState or replaceState

Events

Broadcasted before a URL will change.

This change can be prevented by calling preventDefault method of the event. See $rootScope.Scope for more details about event object. Upon successful change $locationChangeSuccess is fired.

The newState and oldState parameters may be defined only in HTML5 mode and when the browser supports the HTML5 History API.

Type:

broadcast

Target:

root scope

Parameters

Param	Type	Details
angularEvent	`Object`	Synthetic event object.
newUrl	`string`	New URL
oldUrl (optional)	`string`	URL that was before it was changed.
newState (optional)	`string`	New history state object
oldState (optional)	`string`	History state object that was before it was changed.

$locationChangeSuccess

Broadcasted after a URL was changed.

The newState and oldState parameters may be defined only in HTML5 mode and when the browser supports the HTML5 History API.

Type:

broadcast
