<script>
function changecolor(obj) {
obj.style.color="white";
obj.parentElement.parentElement.parentElement.parentElement.parentElement.style.backgroundColor = "#9999cc";
}function changeback(obj) {
status = "";
obj.style.color="black";
obj.parentElement.parentElement.parentElement.parentElement.parentElement.backgroundColor = "#D3D3D3";
}
</script>
如果加上css是不是就不行了呢？看下面的代码
<html><head>
<style type="text/css">
.TableHead{  background-color: #D3D3D3;text-align: center;font-family: Arial;font-size: 12px}
</style>
<script>
function changecolor(obj) {
obj.style.color="white";
obj.parentElement.parentElement.parentElement.parentElement.style.backgroundColor = "#9999cc";
} function changeback(obj) {
status = "";
obj.style.color="black";
obj.parentElement.parentElement.parentElement.parentElement.style.backgroundColor = "#D3D3D3";
}
</script>
</head><body><table border="1" style="border-collapse: collapse" bordercolor="#111111" width="100%" id="AutoNumber1">
  <tr>
    <td width="50%" class="TableHead">
<table>
<tr>
<td class="TableHead">
</td>
<td align="center" class="TableHead" onMouseover="changecolor(this)" onMouseout="changeback(this)" style="cursor:hand">
asdfasf
</td>
<td width="1%" align=right class="TableHead">
</td>
</tr>
</table>
</td>
<td width="50%">　</td>
  </tr>
  <tr>
    <td width="50%">　</td>
    <td width="50%">　</td>
  </tr>
</table></body></html>
用ID就可以了
<script>
function changeback() {
aaa.style.color="#11111";
}
</script>
<table>
<tr>
<td id="aaa" onMouseover="changeback()" >aaaaa</td>
</tr>
</table>
