ExternalInterface

The ExternalInterface class is an application programming interface that * enables straightforward communication between ActionScript and the SWF * container– for example, an HTML page with JavaScript or a desktop * application that uses Flash Player to display a SWF file. *

Using the ExternalInterface class, you can call an ActionScript function * in the Flash runtime, using JavaScript in the HTML page. The ActionScript * function can return a value, and JavaScript receives it immediately as the * return value of the call.
