Flex 與 JavaScript 交互，主要依靠Flex的ExternalInterface，其提供了addCallBack和call方法.
下面的例子將演示Flex調(diào)用javascript，和javascript調(diào)用Flex

javascript代碼：

代碼 function?hello(param)?{????
????alert(param);????
????return?"jsp?Hello:"?+?param;????
}????
???
function?callFlexFunction()?{????
????var?x?=?document.getElementById("flexObject").flexHelloWorld("Hello",?"world");????
????alert(x);????
}???

?

Flex代碼：

?

代碼 <?xml?version="1.0"?encoding="utf-8"?>???
<mx:Application?xmlns:mx="http://www.adobe.com/2006/mxml"?layout="absolute"???
????initialize="initApp()">???
????????
????<mx:Script>???
????????<![CDATA????
????????????import?mx.controls.Alert;????
????????????
????????????public?function?flexHelloWorld(param1:String,?param2:String):String?{????
????????????????Alert.show("param1:?"?+?param1?+?";?param2:"?+?param2);????
????????????????return?"Hello?"?+?param1?+?param2;????
????????????}????
????????????????
????????????public?function?initApp():void?{????
????????????????ExternalInterface.addCallback("flexHelloWorld",?flexHelloWorld);????
????????????}????
????????????????
????????????public?function?jspHello():void?{????
????????????????var?s:String?=?ExternalInterface.call("hello",?"Flex");????
????????????????Alert.show(s);????
????????????}????
????????????????
????????]]>???
????</mx:Script>???
????????
????<mx:Button?x="52"?y="58"?label="call?javascript"?click="jspHello()"/>???
????????
</mx:Application>???
