Getting Return values when calling JavaScript Functions from ActionScript / Flash

I added a page to the Flash / JavaScript Integration Kit project documents that shows how to get return values from JavaScript when calling JavaScript functions from Flash.

The same technique works when calling Flash function from JavaScript, by just reversing the code.

You can view the code / example here.

You can find out more about the Flash / JavaScript Integration Kit here.

    In your code example for broadcasting an event – you have in the Class MyClass//declare EventDispatcher functionsprivate function dispatchEvent;public function addEventListener;public function removeEventListener;shouldn’t that beprivate var dispatchEvent:Function;public var addEventListener:Function;public var removeEventListener:Function;Mike

    Sorry Mike i’m certainly a stupid guy but when i include your code (actionscript part) in flash and want to test syntax…Flash, say it enable to include a class like that, have put in an external .as file.if i do that how to call the class ?yes i know this is certainly very easy for your guru level, but not for mine…. ;(please give us a .fla file or a zip file or a better tutorial ;) (sorry for that).best regardand great job when it’ll work for me.
