ExternalInterface.call(“js方法名”,“方法入参”);

2.JavaScript调用Flash中的方法
Flash中注册ExternalInterface.addCallback(“供js调用的方法”, flash方法);

例子：

exp.html

<html>
<head>
<title>swfobject demo</title>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
function jsAlert(txt)
{
alert(txt);
}
function flashAlert()
{
var obj = document.getElementById("demo");
obj.flashAlert();
}
</script>
</head>
<body>
<div id="content">
NO Flash Player or NO Support This Flash Player!
</div>
<script type="text/javascript">
var so = new SWFObject("Testjs.swf", "demo", "640", "480", "10", "#000000");
so.addParam("wmode", "transparent");
so.addParam("allowFullScreen", "true");
so.write("content");
</script>
<input type="Button" value="警告" onclick="flashAlert()"/>
</body>
</html>

exp.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="<a href="http://www.adobe.com/2006/mxml" rel="nofollow">http://www.adobe.com/2006/mxml</a>" layout="absolute" creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
import flash.external.ExternalInterface;
private function init():void
{
ExternalInterface.addCallback("flashAlert", flashAlertTest);
}
private function doAlert(evt:Event):void
{
ExternalInterface.call("jsAlert", "js Alert");
}
private function flashAlertTest():void
{
Alert.show("flash Alert");
}
]]>
</mx:Script>
<mx:Button x="36" y="97" label="提示" click="doAlert(event)"/>
<mx:Label x="36" y="64" text="Flash调用js" width="135" height="25"/>
</mx:Application>

注意：
1. exp.html, exp.mxml, swfobject.js必须放到web服务器中，直接在本地打开，会出错：SecurityError:Error #2060:安全沙箱冲突:ExternalInterface调用者…

2. ExternalInterface.addCallback(“flashAlert”, flashAlertTest); 必须包含在方法中，然后触发它；否则，会出错：1120:访问的属性flashAlertTest未定义。
如：

private function init():void
{
ExternalInterface.addCallback("flashAlert", flashAlertTest);
}

init();
