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>
