# What does it do?

The `$location` service parses the URL in the browser address bar (based on the [window.location](https://developer.mozilla.org/en/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.
- Maintains synchronization between itself and the browser's URL when the user
  - Changes the address in the browser's address bar.
  - Clicks the back or forward button in the browser (or clicks a History link).
  - Clicks on a link in the page.
- Represents the URL object as a set of methods (protocol, host, port, path, search, hash).

## When should I use $location?
Any time your application needs to react to a change in the current URL or if you want to change
the current URL in the browser.

## What does it not do?
It does not cause a full page reload when the browser URL is changed. To reload the page after
changing the URL, use the lower-level API, `$window.location.href`.

# General overview of the API

The `$location` service can behave differently, depending on the configuration that was provided to
it when it was instantiated. The default configuration is suitable for many applications, for
others customizing the configuration can enable new features.

Once the `$location` service is instantiated, you can interact with it via jQuery-style getter and
setter methods that allow you to get or change the current URL in the browser.

## $location service configuration

To configure the `$location` service, retrieve the
{@link ng.$locationProvider $locationProvider} and set the parameters as follows:


- **html5Mode(mode)**: {boolean|Object}<br />
  `true` or `enabled:true` - see HTML5 mode<br />
  `false` or `enabled:false` - see Hashbang mode<br />
  `requireBase:true` - see Relative links<br />
  default: `enabled:false`

- **hashPrefix(prefix)**: {string}<br />
  prefix used for Hashbang URLs (used in Hashbang mode or in legacy browser in Html5 mode)<br />
  default: `""`

### Example configuration
```js
$locationProvider.html5Mode(true).hashPrefix('!');
```

## Getter and setter methods

`$location` service provides getter methods for read-only parts of the URL (absUrl, protocol, host,
port) and getter / setter methods for url, path, search, hash:
```js
// get the current path
$location.path();

// change the path
$location.path('/newValue')
```

All of the setter methods return the same `$location` object to allow chaining. For example, to
change multiple segments in one go, chain setters like this:

```js
$location.path('/newValue').search({key: value});
```

## Replace method

There is a special `replace` method which can be used to tell the $location service that the next
time the $location service is synced with the browser, the last history record should be replaced
instead of creating a new one. This is useful when you want to implement redirection, which would
otherwise break the back button (navigating back would retrigger the redirection). To change the
current URL without creating a new browser history record you can call:

```js
  $location.path('/someNewPath');
  $location.replace();
  // or you can chain these as: $location.path('/someNewPath').replace();
```

Note that the setters don't update `window.location` immediately. Instead, the `$location` service is
aware of the {@link ng.$rootScope.Scope scope} life-cycle and coalesces multiple `$location`
mutations into one "commit" to the `window.location` object during the scope `$digest` phase. Since
multiple changes to the $location's state will be pushed to the browser as a single change, it's
enough to call the `replace()` method just once to make the entire "commit" a replace operation
rather than an addition to the browser history. Once the browser is updated, the $location service
resets the flag set by `replace()` method and future mutations will create new history records,
unless `replace()` is called again.

### Setters and character encoding
You can pass special characters to `$location` service and it will encode them according to rules
specified in [RFC 3986](http://www.ietf.org/rfc/rfc3986.txt). When you access the methods:

- All values that are passed to `$location` setter methods, `path()`, `search()`, `hash()`, are
encoded.
- Getters (calls to methods without parameters) return decoded values for the following methods
`path()`, `search()`, `hash()`.
- When you call the `absUrl()` method, the returned value is a full url with its segments encoded.
- When you call the `url()` method, the returned value is path, search and hash, in the form
`/path?search=a&b=c#hash`. The segments are encoded as well.


# Hashbang and HTML5 Modes

`$location` service has two configuration modes which control the format of the URL in the browser
address bar: **Hashbang mode** (the default) and the **HTML5 mode** which is based on using the
HTML5 [History API](http://www.w3.org/TR/html5/introduction.html#history-0). Applications use the same API in
both modes and the `$location` service will work with appropriate URL segments and browser APIs to
facilitate the browser URL change and history management.

    <td>yes</td>
  </tr>
</tbody>
</table>

## Hashbang mode (default mode)

In this mode, `$location` uses Hashbang URLs in all browsers.
Angular also does not intercept and rewrite links in this mode. I.e. links work
as expected and also perform full page reloads when other parts of the url
than the hash fragment was changed.


### Example

```js
it('should show example', inject(
  function($locationProvider) {
    $locationProvider.html5Mode(false);
    $locationProvider.hashPrefix('!');
  },
  function($location) {
    // open http://example.com/base/index.html#!/a
    $location.absUrl() == 'http://example.com/base/index.html#!/a'
    $location.path() == '/a'

    $location.path('/foo')
    $location.absUrl() == 'http://example.com/base/index.html#!/foo'

    $location.search() == {}
    $location.search({a: 'b', c: true});
    $location.absUrl() == 'http://example.com/base/index.html#!/foo?a=b&c'

    $location.path('/new').search('x=y');
    $location.absUrl() == 'http://example.com/base/index.html#!/new?x=y'
  }
));
```

## HTML5 mode

In HTML5 mode, the `$location` service getters and setters interact with the browser URL address
through the HTML5 history API. This allows for use of regular URL path and search segments,
instead of their hashbang equivalents. If the HTML5 History API is not supported by a browser, the
`$location` service will fall back to using the hashbang URLs automatically. This frees you from
having to worry about whether the browser displaying your app supports the history API  or not; the
`$location` service transparently uses the best available option.

- Opening a regular URL in a legacy browser -> redirects to a hashbang URL
- Opening hashbang URL in a modern browser -> rewrites to a regular URL

Note that in this mode, Angular intercepts all links (subject to the "Html link rewriting" rules below)
and updates the url in a way that never performs a full page reload.


### Example

```js
it('should show example', inject(
  function($locationProvider) {
    $locationProvider.html5Mode(true);
    $locationProvider.hashPrefix('!');
  },
  function($location) {
    // in browser with HTML5 history support:
    // open http://example.com/#!/a -> rewrite to http://example.com/a
    // (replacing the http://example.com/#!/a history record)
    $location.path() == '/a'

    $location.path('/foo');
    $location.absUrl() == 'http://example.com/foo'

    $location.search() == {}
    $location.search({a: 'b', c: true});
    $location.absUrl() == 'http://example.com/foo?a=b&c'

    $location.path('/new').search('x=y');
    $location.url() == 'new?x=y'
    $location.absUrl() == 'http://example.com/new?x=y'

    // in browser without html5 history support:
    // open http://example.com/new?x=y -> redirect to http://example.com/#!/new?x=y
    // (again replacing the http://example.com/new?x=y history item)
    $location.path() == '/new'
    $location.search() == {x: 'y'}

    $location.path('/foo/bar');
    $location.path() == '/foo/bar'
    $location.url() == '/foo/bar?x=y'
    $location.absUrl() == 'http://example.com/#!/foo/bar?x=y'
  }
));
```

### Fallback for legacy browsers

For browsers that support the HTML5 history API, `$location` uses the HTML5 history API to write
path and search. If the history API is not supported by a browser, `$location` supplies a Hasbang
URL. This frees you from having to worry about whether the browser viewing your app supports the
history API  or not; the `$location` service makes this transparent to you.

### Html link rewriting

When you use HTML5 history API mode, you will not need special hashbang links. All you have to do
is specify regular URL links, such as: `<a href="/some?foo=bar">link</a>`

When a user clicks on this link,

- In a legacy browser, the URL changes to `/index.html#!/some?foo=bar`
- In a modern browser, the URL changes to `/some?foo=bar`


In cases like the following, links are not rewritten; instead, the browser will perform a full page
reload to the original link.

- Links that contain `target` element<br>
  Example: `<a href="/ext/link?a=b" target="_self">link</a>`
- Absolute links that go to a different domain<br>
  Example: `<a href="http://angularjs.org/">link</a>`
- Links starting with '/' that lead to a different base path<br>
  Example: `<a href="/not-my-base/link">link</a>`


### Relative links

Be sure to check all relative links, images, scripts etc. Angular requires you to specify the url
base in the head of your main html file (`<base href="/my-base">`) unless `html5Mode.requireBase` is
set to `false` in the html5Mode definition object passed to `$locationProvider.html5Mode()`. With
that, relative urls will always be resolved to this base url, even if the initial url of the
document was different.

There is one exception: Links that only contain a hash fragment (e.g. `<a href="#target">`)
will only change `$location.hash()` and not modify the url otherwise. This is useful for scrolling
to anchors on the same page without needing to know on which page the user currently is.

### Server side

Using this mode requires URL rewriting on server side, basically you have to rewrite all your links
to entry point of your application (e.g. index.html). Requiring a `<base>` tag is also important for
this case, as it allows Angular to differentiate between the part of the url that is the application
base and the path that should be handled by the application.

### Sending links among different browsers

Because of rewriting capability in HTML5 mode, your users will be able to open regular url links in
legacy browsers and hashbang links in modern browser:

- Modern browser will rewrite hashbang URLs to regular URLs.
- Older browsers will redirect regular URLs to hashbang URLs.

### Example

Here you can see two `$location` instances, both in **Html5 mode**, but on different browsers, so
that you can see the differences. These `$location` services are connected to a fake browsers. Each
input represents address bar of the browser.

Note that when you type hashbang url into first browser (or vice versa) it doesn't rewrite /
redirect to regular / hashbang url, as this conversion happens only during parsing the initial URL
= on page reload.

In these examples we use `<base href="/base/index.html" />`

# Caveats

## Page reload navigation

The `$location` service allows you to change only the URL; it does not allow you to reload the
page. When you need to change the URL and reload the page or navigate to a different page, please
use a lower level API, {@link ng.$window $window.location.href}.

## Using $location outside of the scope life-cycle

`$location` knows about Angular's {@link ng.$rootScope.Scope scope} life-cycle. When a URL changes in
the browser it updates the `$location` and calls `$apply` so that all
{@link ng.$rootScope.Scope#$watch $watchers} /
{@link ng.$compile.directive.Attributes#$observe $observers} are notified.
When you change the `$location` inside the `$digest` phase everything is ok; `$location` will
propagate this change into browser and will notify all the {@link ng.$rootScope.Scope#$watch $watchers} /
{@link ng.$compile.directive.Attributes#$observe $observers}.
When you want to change the `$location` from outside Angular (for example, through a DOM Event or
during testing) - you must call `$apply` to propagate the changes.

## $location.path() and ! or / prefixes

A path should always begin with forward slash (`/`); the `$location.path()` setter will add the
forward slash if it is missing.

Note that the `!` prefix in the hashbang mode is not part of `$location.path()`; it is actually
hashPrefix.

## Crawling your app

To allow indexing of your AJAX application, you have to add special meta tag in the head section of
your document:

```html
<meta name="fragment" content="!" />
```

This will cause crawler bot to request links with `_escaped_fragment_` param so that your server
can recognize the crawler and serve a HTML snapshots. For more information about this technique,
see [Making AJAX Applications
Crawlable](http://code.google.com/web/ajaxcrawling/docs/specification.html).


# Testing with the $location service

When using `$location` service during testing, you are outside of the angular's {@link
ng.$rootScope.Scope scope} life-cycle. This means it's your responsibility to call `scope.$apply()`.

```js
describe('serviceUnderTest', function() {
  beforeEach(module(function($provide) {
    $provide.factory('serviceUnderTest', function($location){
      // whatever it does...
    });
  });

  it('should...', inject(function($location, $rootScope, serviceUnderTest) {
    $location.path('/new/path');
    $rootScope.$apply();

    // test whatever the service should do...

  }));
});
```


# Migrating from earlier AngularJS releases

In earlier releases of Angular, `$location` used `hashPath` or `hashSearch` to process path and
search methods. With this release, the `$location` service processes path and search methods and
then uses the information it obtains to compose hashbang URLs (such as
`http://server.com/#!/path?search=a`), when necessary.

## Two-way binding to $location

Because `$location` uses getters/setters, you can use `ng-model-options="{ getterSetter: true }"`
to bind it to `ngModel`:

<example module="locationExample">
<file name="index.html">
<div ng-controller="LocationController">
  <input type="text" ng-model="locationPath" ng-model-options="{ getterSetter: true }" />
</div>
</file>
<file name="script.js">
angular.module('locationExample', [])
  .controller('LocationController', ['$scope', '$location', function($scope, $location) {
    $scope.locationPath = function (newLocation) {
      return $location.path(newLocation);
    };
  }]);
</file>
</example>
