在flash代码中加入以下代码,层就会浮在flash上面
<param name="wmode" value="opaque">
或者
<param name="wmode" value="transparent" />

以上方法ie有效 火狐不行

这个代码通用

<script src="AC_RunActiveContent.js" type="text/javascript"></script>

<script type="text/javascript">
AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0','width','1004','height','317','src','swf/top','quality','high','pluginspage','http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash','wmode','transparent','menu','false','movie','banner' ); //end AC code
</script>
AC_RunActiveContent.js
