Example
The following example uses
ExternalInterface.available to determine whether the
player is in a container that offers an external interface.
import flash.external.*;
var isAvailable:Boolean = ExternalInterface.available;
trace(isAvailable);
call (ExternalInterface.call method)
public static call(methodName:String, [parameter1:Object]) : Object
Calls a function exposed by the Flash Player container, passing 0 or more arguments. If the
desired function is not available, the call returns
null; otherwise it returns the value provided
by the function. Recursion is not permitted; a recursive call produces a
null response.
If the container is an HTML page, this method invokes a JavaScript function in a <script>
element.
If the container is some other ActiveX container, this method broadcasts an event with the
specified name, and the container processes the event.
