JS和Flash互相调用Function不成功，请教高手

本人最近开始学习flash，需要用到js和flash互相调用function，根据资料使用FLash的ExternalInterface的call和addCallback方法，但是没有成功，本人使用的是Flash CS4，用的AS3.0，代码如下，请各位高手指点。
页面代码html：

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>test</title>

<script language="JavaScript">

	 var jsReady = false;

     function isReady() {

         return jsReady;

     }

     function pageInit() {

         jsReady = true;

     }

     function thisMovie(movieName) {

         if (navigator.appName.indexOf("Microsoft") != -1) {

             return window[movieName];

         } else {

             return document[movieName];

         }

     }

	 function test(){

		 alert("成功！");

	 }

	 function cpu(){

		 thisMovie("2").jstest();

	 }

</script>

</head>

<body onLoad="pageInit();">

<table>

	<tr>

    	<td>

        	<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

             id="2" width="500" height="375"

             codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab">

         <param name="movie" value="2.swf" />

         <param name="quality" value="high" />

         <param name="bgcolor" value="#869ca7" />

         <param name="allowScriptAccess" value="sameDomain" />

         <embed src="2.swf" quality="high" bgcolor="#869ca7"

             width="500" height="375" name="2" align="middle"

             play="true" loop="false" allowScriptAccess="sameDomain"

             type="application/x-shockwave-flash"

             pluginspage="http://get.adobe.com/flashplayer/">

         </embed>

     </object>

        </td>

    </tr>

    <tr>

    	<td>

        	<input name="test" type="button" value="test" onclick="cpu();" />

        </td>

    </tr>

</table>

</body>

</html>

对于的flash代码，本人是在一个名叫2.fla的第一个图层上的第一帧添加动作，编辑的一下代码：
import flash.external.ExternalInterface;

var output:TextField=new TextField();//js调用状态显示文本
var readyTimer:Timer=new Timer(100,0);

if (ExternalInterface.available) {
try {
output.appendText(checkJavaScriptReady());
if (checkJavaScriptReady()) {
output.appendText("JavaScript is ready.\n");
ExternalInterface.call("test");
ExternalInterface.addCallback("jstest",jstest);
} else {
output.appendText("JavaScript is not ready, creating timer.\n");
readyTimer.addEventListener(TimerEvent.TIMER, timerHandler);
readyTimer.start();
}
} catch (error:SecurityError) {
output.appendText("A SecurityError occurred(安全错误): " + error.message + "\n");
} catch (error:Error) {
output.appendText("A SecurityError occurred(错误): " + error.message + "\n");
}
} else {
output.appendText("External interface不可用。");
};

function checkJavaScriptReady() {
var isReady:Boolean=ExternalInterface.call("isReady");
return isReady;
}

function timerHandler(event:TimerEvent):void {
var isReady:Boolean=checkJavaScriptReady();
if (isReady) {
ExternalInterface.addCallback("jstest",jstest);
Timer(event.target).stop();
}
}

function jstest():void {
ExternalInterface.call("test");
}

小弟在线求指导，谢谢
