html部分：

代碼如下:

<div id=ad2 style=z-index: 5;position:relative><a href='policehtk.aspx' target='_blank'><img src=images/fudong/fudong.jpg width=230 height=150 border=0 > </a><br> <a href=# onclick=document.getelementbyid('ad2').style.display='none'> <img border=0 src=images/fudong/close1.gif /></a>

</div>
