ActionScript to Javascript Communication

In my last post I showed how to communicate from Javascript to ActionScript.  To do so I used ExternalInterface in my ActionScript.  ExternalInterface allows traffic to flows both ways.

We’ll start in ActionScript this time.  Ensure you have imported the ExternalInterface class.

import flash.external.ExternalInterface;

Then create a call to Javascript using the ‘call’ method of the ExternalInterface class.

ExternalInterface.call("sayHello");

You’ll in all likelihood be placing that inside an event like a button click.

In your HTML document now add a Javascript function using the same name in the ActionScript call ie:

function sayHello(){
	// do something
}
