Flex和JavaScript之间通信

在JavaScript页面调用Flex的方法:

JS页面代码:

<script type="text/javascript">
	function callApp() {
         var x = index.myFlexFunction(1);
         alert(x);
     	}
</script>
<input type="button" value="click" onclick="callApp()" />

<mx:Script>
     import flash.external.*;
     public function myFunc():Number {
         return 42;
     }
     public function initApp():void {
         ExternalInterface.addCallback("myFlexFunction",myFunc);
     }
</mx:Script>
