正常情况下我们在网页中插入一个Flash文件后网页源文件会出现如下代码，只要在这段代码里加入<param name="WMODE" value="transparent"> 就可以避免网站商务通的邀请界面被Flash遮住了： 

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 

codebase="http://download.macromedia.com/pub/shockwave/cabs/flash
/swflash.cab#version=5,0,42,0" id="f1" width="494" height="167" VIEWASTEXT>  

    <param name="movie" value="../cnimages/1.swf">  

    <param name="bgcolor" value="#FFFFFF">  

       <param name="WMODE" value="transparent"> 

    <param name="quality" value="high">  

    <param name="allowscriptaccess" value="samedomain">  

    <embed type="application/x-shockwave-flash" 

                pluginspage="http://www.macromedia.com/go/getflashplayer" 

                width="494" height="167" 

                name="f1" src="../cnimages/1.swf" 

                bgcolor="#FFFFFF" quality="high" 

                swLiveConnect="true" allowScriptAccess="samedomain" ></embed>  

 </object>
