Cordova WKWebView External Screen plugin

A super basic Cordova plugin for displaying and interacting with an HTML document on an external screen via AirPlay or HDMI adapter utilizing the WKWebView in iOS 8+.

(cordova-plugin-wkwebview-engine must be installed separately)

Installation

With cordova-cli

If you are using cordova-cli, install with:

cordova plugin add cordova-plugin-wkwebview-external-screen

Or directly from this repo:

cordova plugin add https://github.com/josiaho/cordova-plugin-wkwebview-external-screen.git

Usage

The plugin is available under the global ExternalScreen object.

Example:

ExternalScreen.checkAvailability(function (isAvailable) {
	if (isAvailable) { // If an external screen is available
		ExternalScreen.loadHTML('secondary.html'); // Load document
	}
})

.checkAvailability

Determines whether an External Screen is currently available (via AirPlay mirroring or HDMI adapter)

ExternalScreen.checkAvailability(function (isAvailable) {
	alert(isAvailable) // true or false
})

.loadHTML

The .html file you would like to display on the External Screen (the file must be located in your app's www directory).

ExternalScreen.loadHTML('secondary.html');

(This method will fail if external screen is unavailable)

.invokeJavaScript

Communicate with the external page by sending scripts which will be evaluated:

ExternalScreen.invokeJavaScript('myFunction("Hello World")');

The script needs to be serialized to a string. Any values you pass should also be serialized before calling invokeJavaScript().

(This method will fail if external screen is unavailable)
