Flash/Flex学习笔记(9)：ActionScript3.0与Javascript的相互调用

btnCallJs.addEventListener(MouseEvent.CLICK,fnCallJs);

function fnCallJs(e:MouseEvent):void {
	trace("准备调用...");
	//调用js中的JsHello方法，并将返回值显示到Label中
	lblResult.text=ExternalInterface.call("JsHello","AS3传递的参数");
}

function CalledByJs(p:String):String {
	return "Flash中的CalledByJs被调用了，这是js中传过来的参数：" + p;
}

ExternalInterface.addCallback("MyFunction",CalledByJs);//这里：MyFunction就是暴露给js调用的方法名称

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" ... id="Js_AS3" >
	...	</object>


<script type="text/javascript">
function JsHello(msg){
	var r = "这是js中的方法，参数：" + msg;
	alert(r);
	return r;
}

function fnCallAs(msg){
	var flashObj = document.getElementById("Js_AS3");	
	var sAsReturn = flashObj.MyFunction("js中的参数");
	alert(sAsReturn);
}

fnCallAs("test");

</script>
