flex与flash元件交互

前一段时间发了flex与JavaScript的数据交互 ，现在学习如果跟flash的交互

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
  <mx:Script>
    <![CDATA[
      private function btn1Click(e:MouseEvent):void{
        var mc:MovieClip = swfload.content as MovieClip;
        mc.act1();
      }
     
      private function btn2Click(e:MouseEvent):void{
        var mc:MovieClip = swfload.content as MovieClip;
        mc.act2();
      }
    ]]>
  </mx:Script>
<mx:SWFLoader id="swfload" source="MovieTest.swf"/>
<mx:Button id="btn1" label="Btn1" click="btn1Click(event)" x="62" y="379"/>
<mx:Button id="btn2" label="Btn2" click="btn2Click(event)" x="212" y="379"/>
</mx:Application>

假设我在flsah的一个元件上写下了如果ActionScript3代码

function act1():void{
	gotoAndStop(1);    
}

function act2():void{
	paly();    
}
