JavaScript通过代码调用Flash显示的方法

<script type="text/javascript" language="javascript" src="Scripts/swfobject.js"></script>
<script language="javascript">
  function load(){
    var swfVersionStr = "10.0.0";
    var params = {};
    params.quality = "high";
    params.allowfullscreen = "false";
    params.allowscriptaccess = "always";
    //params.wmode = "transparent";
    swfobject.embedSWF("flash/MainPage.swf", "FlashID", "597", "416", swfVersionStr,params);
  }
  //调用flash中的方法，"swfId"为html页中swf的id
  function setValue(o) {
    thisMovie("FlashID").getIds(o);
  }
  //搭建js与flash互通的环境
  function thisMovie(movieName) {
    if (navigator.appName.indexOf("Microsoft") != -1) {
     return window[movieName];
    } else {
     return document[movieName];
    }
  }
</script>
