onmouseover/out与div的问题

Question

用onmouseenter和onmouseleave 代替onmouseover和onmouseout

Answer 1

经过测试，光是div嵌套不会出现楼主说的情况，如果里层含有table则如楼主所说，测试代码如下
<script type="text/javascript">
function a1()
{
document.getElementById("a").innerHTML = "in";
}
function a2()
{
document.getElementById("a").innerHTML = "out";
}
</script>
<div style="border-style:solid; border-width:thin" onMouseOver="javascript:a1();" onMouseOut="javascript:a2();">
  
  0&nbsp;0&nbsp;0
  
  <div style="border-style:solid; border-width:thin; border-color:#FF0000">
    1&nbsp;1&nbsp;1
  </div>  <div style="border-style:solid; border-width:thin; border-color:#FF00FF">
<table>
  <tbody>
<tr>
  <td>
2&nbsp;2&nbsp;2
  </td>
</tr>
  </tbody>
</table>
  </div></div>
<div id="a"></div>onmouseenter和onmouseleave不是标准事件，兼容性...
