如何显示层

[jxnucsb2008]

<td align="center" onMouseOver="MM_showHideLayers('esave','','show')" onMouseOut="MM_showHideLayers('esave','','hide')" >
<a href="#">把鼠标放在上面就显示层</a>
<div id="esave" style="position:absolute; top:68px; left:118px; z-index:10;visibility:hidden; width: 168px; height: 120px;">
<table width=100% height=120 border=0 cellspacing=1 cellpadding=0>
<tr>
<td bgcolor=#ffffff align="left" valign="top">内容介绍：<br>
<font color=red><%=adoRS("shuoming")%></font></td>
</tr>
</table>
</div></td>

在DW中设置下默认为隐藏，移上的动作发生时显示，代码会自动生成的
