需要引入import flash.external.ExternalInterface;
一、ActionScript调用JavaScript的方法
这里要用到ExternalInterface类的call方法
ExternalInterface.call(functionName:String,...arguments):*
fuctionName:要调用的JavaScript函数名
arguments:参数，可选
1.不带参数的情况
JavaScript：function Show() { alert("I am a func!");}
ActionScript：//直接用一条语句调用ExternalInterface.call("Show");
2.带参数的情况
JavaScript：function Show(message) { alert(message);}
ActionScript：ExternalInterface.call("Show","I am a message from AS"); 另外，也可以用getURL方法来调用
getURL("javascript:show('i am a message from as)","_self");
二、JavaScript调用ActionScript的方法
这要用到ExternalInterface类的addCallback方法
ExternalInterface.addCallback( functionName:String, closure:Function):void
functionName:要注册的函数名
closure:对应的执行函数
ActionScript：ExternalInterface.addCallback("Show",OnShow);private function OnShow(message:String):string{return message;}
JavaScript：function thisMovie(movieName){ if(navigator.appName.indexOf("Microsoft") != -1){ return window[movieName]; }else{ return document[movieName]; }} function CallAS( ) { thisMovie("ViewLesson").Show("i am a message from js");//ViewLesson是flash媒体的ID}
HTML：<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="ViewLesson" width="100%" height="100%" codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab"> <param name="movie" value="ViewLesson.swf" /> <param name="quality" value="high" /> <param name="bgcolor" value="#869ca7" /> <param name="allowScriptAccess" value="sameDomain" /> <embed src="ViewLesson.swf" quality="high" bgcolor="#869ca7" width="100%" height="100%" name="ViewLesson" align="middle" play="true" loop="false" quality="high" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer"> </embed> </object>
