xiyou 大哥，按照你的方法试过了，可还是和以前一样啊，下面是我banner的代码，你看一下（没替换前的代码）
<table border="0" cellspacing="0" cellpadding="0" width="100%">
<tbody>
<tr>
<td width="80%">
<div id="newsad" class="newsad" style="height: 30px; overflow: hidden"> </div>
<script type="text/javascript">
function ajax_80_fun(v)
{
$("newsad").innerHTML=v;
var M=new Marquee("newsad","top",1,null,null,20,3000,30,1000);
}
</script></td>
<td width="15%"><script src=/e/js/date.js type="text/javascript"></script></td>
</tr>
</tbody>
</table>
<div style="display: none"><script src="/e/aspx/ajax_list.aspx?modelid=80" type="text/javascript"></script><script type="text/javascript">
var ajaxparameter_80="siteid=1"
rajax_80(1);
</script></div>
