做了一个弹出窗口，点击后发现它和flash重合的部分，被flash盖住了，查了一下解决方法：
原代码如下：
<object classid='clsid:D27CDB6E-AE6D-11CF-96B8-444553540000' id='obj6' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0' border='0' width='266' height='139'>
<param name='movie' value='flash/pics.swf?httpx=xml/pics.xml'>
<param name='quality' value='High'>
<embed src='flash/pics.swf?httpx=xml/pics.xml' pluginspage='http://www.macromedia.com/go/getflashplayer' type='application/x-shockwave-flash' name='obj6' width='266' height='139' quality='High'></embed>
</object>
修改后代码：
<object classid='clsid:D27CDB6E-AE6D-11CF-96B8-444553540000' id='obj6' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0' border='0' width='266' height='139'>
<param name='movie' value='flash/pics.swf?httpx=xml/pics.xml'>
<param name='quality' value='High'><param value='transparent'>
<embed src='flash/pics.swf?httpx=xml/pics.xml' pluginspage='http://www.macromedia.com/go/getflashplayer' type='application/x-shockwave-flash' name='obj6' width='266' height='139' quality='High' wmode='opaque'></embed>
</object>
其中红色的是解决在ie下被挡住的问题，蓝色的是解决在firefox下被挡住的问题。
