# org.apache.cordova.inappbrowser

This plugin provides a web browser view that displays when calling `window.open()`, or when opening a link formed as `<a target="_blank">`.

    var ref = window.open('http://apache.org', '_blank', 'location=yes');

__NOTE__: The InAppBrowser window behaves like a standard web browser,
and can't access Cordova APIs.

## Installation

    cordova plugin add org.apache.cordova.inappbrowser

## window.open

Opens a URL in a new `InAppBrowser` instance, the current browser
instance, or the system browser.

    var ref = window.open(url, target, options);

- __ref__: Reference to the `InAppBrowser` window. _(InAppBrowser)_

- __url__: The URL to load _(String)_. Call `encodeURI()` on this if the URL contains Unicode characters.

- __target__: The target in which to load the URL, an optional parameter that defaults to `_self`. _(String)_

    - `_self`: Opens in the Cordova WebView if the URL is in the white list, otherwise it opens in the `InAppBrowser`.
    - `_blank`: Opens in the `InAppBrowser`.
    - `_system`: Opens in the system's web browser.

- __options__: Options for the `InAppBrowser`. Optional, defaulting to: `location=yes`. _(String)_

    The `options` string must not contain any blank space, and each feature's name/value pairs must be separated by a comma. Feature names are case insensitive. All platforms support the value below:

    - __location__: Set to `yes` or `no` to turn the `InAppBrowser`'s location bar on or off.

    Android only:

    - __closebuttoncaption__: set to a string to use as the __Done__ button's caption.
    - __hidden__: set to `yes` to create the browser and load the page, but not show it. The loadstop event fires when loading is complete. Omit or set to `no` (default) to have the browser open and load normally.
    - __clearcache__: set to `yes` to have the browser's cookie cache cleared before the new window is opened
    - __clearsessioncache__: set to `yes` to have the session cookie cache cleared before the new window is opened

    iOS only:

    - __closebuttoncaption__: set to a string to use as the __Done__ button's caption. Note that you need to localize this value yourself.
    - __disallowoverscroll__: Set to `yes` or `no` (default is `no`). Turns on/off the UIWebViewBounce property.
    - __hidden__: set to `yes` to create the browser and load the page, but not show it. The loadstop event fires when loading is complete. Omit or set to `no` (default) to have the browser open and load normally.
    - __clearcache__: set to `yes` to have the browser's cookie cache cleared before the new window is opened
    - __clearsessioncache__: set to `yes` to have the session cookie cache cleared before the new window is opened
    - __toolbar__:  set to `yes` or `no` to turn the toolbar on or off for the InAppBrowser (defaults to `yes`)
    - __enableViewportScale__:  Set to `yes` or `no` to prevent viewport scaling through a meta tag (defaults to `no`).
    - __mediaPlaybackRequiresUserAction__: Set to `yes` or `no` to prevent HTML5 audio or video from autoplaying (defaults to `no`).
    - __allowInlineMediaPlayback__: Set to `yes` or `no` to allow in-line HTML5 media playback, displaying within the browser window rather than a device-specific playback interface. The HTML's `video` element must also include the `webkit-playsinline` attribute (defaults to `no`)
    - __keyboardDisplayRequiresUserAction__: Set to `yes` or `no` to open the keyboard when form elements receive focus via JavaScript's `focus()` call (defaults to `yes`).
    - __suppressesIncrementalRendering__: Set to `yes` or `no` to wait until all new view content is received before being rendered (defaults to `no`).
    - __presentationstyle__:  Set to `pagesheet`, `formsheet` or `fullscreen` to set the [presentation style](http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instp/UIViewController/modalPresentationStyle) (defaults to `fullscreen`).
    - __transitionstyle__: Set to `fliphorizontal`, `crossdissolve` or `coververtical` to set the [transition style](http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instp/UIViewController/modalTransitionStyle) (defaults to `coververtical`).
    - __toolbarposition__: Set to `top` or `bottom` (default is `bottom`). Causes the toolbar to be at the top or bottom of the window.

### Supported Platforms

- Amazon Fire OS
- Android
- BlackBerry 10
- Firefox OS
- iOS
- Windows Phone 7 and 8

### Example

    var ref = window.open('http://apache.org', '_blank', 'location=yes');
    var ref2 = window.open(encodeURI('http://ja.m.wikipedia.org/wiki/ハングル'), '_blank', 'location=yes');

### Firefox OS Quirks

As plugin doesn't enforce any design there is a need to add some CSS rules if 
opened with `target='_blank'`. The rules might look like these

``` css
.inAppBrowserWrap {
  background-color: rgba(0,0,0,0.75);
  color: rgba(235,235,235,1.0);
}
.inAppBrowserWrap menu {
  overflow: auto;
  list-style-type: none;
  padding-left: 0;
}
.inAppBrowserWrap menu li {
  font-size: 25px;
  height: 25px;
  float: left;
  margin: 0 10px;
  padding: 3px 10px;
  text-decoration: none;
  color: #ccc;
  display: block;
  background: rgba(30,30,30,0.50);
}
.inAppBrowserWrap menu li.disabled {
	color: #777;
}
```
