很多时候，当你有一个层是需要漂浮在页面之上显示的时候，而你的页面里又存在FLASH，这个时候，漂浮层会被FLASH遮挡住，那么解决办法就是给FLASH设置透明属性。
添加参数<param name="wmode"
value="transparent">
//可很好的被IE浏览器所支持
将 wmode="transparent"
加入到<embed>标签内
//可很好的被FireFox等浏览器所支持
示例：
<noscript>
<object
classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0
"
width="744" height="60">
<param name="movie"
value="Templates/default/images/02.swf" />
<param name="quality" value="high"
/>
<param name="wmode" value="transparent"
/>
<embed src="Templates/default/images/02.swf"
quality="high" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash
"
type="application/x-shockwave-flash" width="744" height="60"
wmode="transparent"></
embed>
</object>
</noscript>
如果是被JS调用显示FLASH，则在调用函数内添加参数'wmode','transparent'
示例：
<script
type="text/javascript">
AC_FL_RunContent(
'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0','width','744','height','60','src','Templates/default/images/02','quality','high','pluginspage','http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash','movie','Templates/default/images/02','wmode','transparent'
); //end AC code
</script>
