做项目的时候经常会遇到DIV浮动层被FLASH遮挡的，下面给出解决方案。

IE下：

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

FireFox和Chrome下：

<embed src="http://player.56.com/v_ODk4OTI0NjA.swf" quality="high" width="480" height="405" wmode="transparent"></embed>

完整格式：

<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="480" height="405">

<param name="movie" value="http://player.56.com/v_ODk4OTI0NjA.swf" />

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

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

<embed src="http://player.56.com/v_ODk4OTI0NjA.swf" quality="high" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="480" height="405" wmode="transparent"></embed>

</object>

注意插入优酷视频和插入flash的方式是一样的， 注意一些标签不可省略
