在IE和FireFox中实现Flash背景透明和解决绝对定位元素被Flash遮住的问题

<div class="Ad"> <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="524" height="132"> <param name="movie" value="../images/flash/xwzx.swf" /> <param name="quality" value="high" /><param name="wmode" value="opaque"><param name="wmode" value="transparent" > <embed src="../images/flash/xwzx.swf" mce_src="images/flash/xwzx.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="524" height="132" wmode="transparent"></embed> </object></div>

在IE中实现背景透明就是加

<param name="wmode" value="opaque">

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

在火狐中就设置

wmode="transparent"

只要使背景透明，绝对定位元素被遮盖的问题也就解决了
