<script type="text/javascript">

} else {
return document[movieName];
}
}
function stopsong() {
thisMovie("audio").stopsong();
alert("ok");
}
</script>

FLash中as3源码：
if (ExternalInterface.available)
{
//交互的核心代码，as接收js发送过来的信息 后面stopSongHandler为as的函数
ExternalInterface.addCallback("stopsong", stopSongHandler);
}
function stopSongHandler():void {
_channel.stop();
}
