# cordova-plugin-inappbrowser
|
|
|
|
This plugin provides a web browser view that displays when calling `cordova.InAppBrowser.open()`.
|
|
|
|
var ref = cordova.InAppBrowser.open('http://apache.org', '_blank', 'location=yes');
|
|
|
|
The `cordova.InAppBrowser.open()` function is defined to be a drop-in replacement
|
|
for the `window.open()` function. Existing `window.open()` calls can use the
|
|
InAppBrowser window, by replacing window.open:
|
|
|
|
window.open = cordova.InAppBrowser.open;
|
|
|
|
The InAppBrowser window behaves like a standard web browser,
|
|
and can't access Cordova APIs. For this reason, the InAppBrowser is recommended
|
|
if you need to load third-party (untrusted) content, instead of loading that
|
|
into the main Cordova webview. The InAppBrowser is not subject to the
|
|
whitelist, nor is opening links in the system browser.
|
|
|
|
The InAppBrowser provides by default its own GUI controls for the user (back,
|
|
forward, done).
|
|
|
|
For backwards compatibility, this plugin also hooks `window.open`.
|
|
However, the plugin-installed hook of `window.open` can have unintended side
|
|
effects (especially if this plugin is included only as a dependency of another
|
|
plugin). The hook of `window.open` will be removed in a future major release.
|
|
Until the hook is removed from the plugin, apps can manually restore the default
|
|
behaviour:
|
|
|
|
delete window.open // Reverts the call back to it's prototype's default
|
|
|
|
Although `window.open` is in the global scope, InAppBrowser is not available until after the `deviceready` event.
|
|
|
|
document.addEventListener("deviceready", onDeviceReady, false);
|
|
function onDeviceReady() {
|
|
console.log("window.open works well");
|
|
}
|

## Installation
|
|
|
|
cordova plugin add cordova-plugin-inappbrowser
|
|
|
|
If you want all page loads in your app to go through the InAppBrowser, you can
|
|
simply hook `window.open` during initialization. For example:
|
|
|
|
document.addEventListener("deviceready", onDeviceReady, false);
|
|
function onDeviceReady() {
|
|
window.open = cordova.InAppBrowser.open;
|
|
}
|
|
|
|
## cordova.InAppBrowser.open
|
|
|
|
Opens a URL in a new `InAppBrowser` instance, the current browser
|
|
instance, or the system browser.
|
|
|
|
var ref = cordova.InAppBrowser.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:
|
|
|
|
- __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
|
|
- __zoom__: set to `yes` to show Android browser's zoom controls, set to `no` to hide them. Default value is `yes`.
|
|
- __hardwareback__: set to `yes` to use the hardware back button to navigate backwards through the `InAppBrowser`'s history. If there is no previous page, the `InAppBrowser` will close. The default value is `yes`, so you must set it to `no` if you want the back button to simply close the InAppBrowser.
|
|
|
|
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.
|
|
|
|
Windows only:
|
|
|
|
- __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.
|
|
- __fullscreen__: set to `yes` to create the browser control without a border around it. Please note that if __location=no__ is also specified, there will be no control presented to user to close IAB window.

### Supported Platforms
|
|
|
|
- Amazon Fire OS
|
|
- Android
|
|
- BlackBerry 10
|
|
- Firefox OS
|
|

|
|
|
### Example
|
|
|
|
var ref = cordova.InAppBrowser.open('http://apache.org', '_blank', 'location=yes');
|
|
var ref2 = cordova.InAppBrowser.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;
|
|
}
|
|
```
|
|
|
|
### Windows Quirks
|
|
|
|
Windows 8.0, 8.1 and Windows Phone 8.1 don't support remote urls to be opened in the Cordova WebView so remote urls are always showed in the system's web browser if opened with `target='_self'`.
|
|
|
|
On Windows 10 if the URL is NOT in the white list and is opened with `target='_self'` it will be showed in the system's web browser instead of InAppBrowser popup.
|
|
|
|
Similar to Firefox OS IAB window visual behaviour can be overridden via `inAppBrowserWrap`/`inAppBrowserWrapFullscreen` CSS classes
|
|
|
|
### Browser Quirks
|
|
|
|
- Plugin is implemented via iframe,
|
|
|
|
- Navigation history (`back` and `forward` buttons in LocationBar) is not implemented.
|
|
|
|
