Flash - FS Commands ActionScript跟JavaScript沟通

在index.htm下输入以下代码
<script language="JavaScript">
<!--
var isInternetExplorer = navigator.appName.indexOf("Microsoft") != -1;
// 处理 Flash 影片中的所有 FSCommand 消息
function flash1_DoFSCommand(command, args) { //flash1用这个名字的原因是swf的名字是flash1.swf,跟网页名字无关
 var flash1Obj = isInternetExplorer ? document.all.flash1 : document.flash1;
 if(command=="test1"){
  alert("123");
 }
 else{
  alert("No FSCommand params rec'd.");
 }
}
// Internet Explorer 的挂钩
if (navigator.appName && navigator.appName.indexOf("Microsoft") != -1 && navigator.userAgent.indexOf("Windows") != -1 && navigator.userAgent.indexOf("Windows 3.1") == -1) {
 document.write('<script language=/"VBScript/"/>/n');
 document.write('On Error Resume Next/n');
 document.write('Sub flash1_FSCommand(ByVal command, ByVal args)/n');
 document.write(' Call flash1_DoFSCommand(command, args)/n');
 document.write('End Sub/n');
 document.write('</script/>/n');
}
//-->
</script>
