<script language="javascript">
function showback1(a,b)
{
eval('td'+a+'').background="js/"+b+".jpg";
}
function shouback11(a,b)
{
eval('td'+a+'').background="js/"+b+".jpg";
}
</script>
以下是td调用
<td width="100" height="89" align="center" valign="bottom" id="td1" style="cursor:hand" background="js/11.jpg" onmouseover="showback1(1,1)" onmouseout="shouback11(1,11)" onclick="window.open('index.asp?id=<%=id%>')"> </td>
