flex 和swf互相調用

as:

var app:Object;

function setApp(ap:Object):void{

this.app=ap;

}

btn.addEventListener(MouseEvent.CLICK,onClick);

function onClick(event:MouseEvent):void{ 

app.fun(btn.label);

} 

flex:

private function onSwfLoaded(event:Event):void

{

  myloader.addEventListener(Event.COMPLETE, loaderHandler);

}

private function loaderHandler(event:Event):void

{

  Object(myloader.content).setApp(this);

}

public function fun(str:String):void

{

  trace(str);

}
