问题,能不能把一个表格内的一次性清空

[xizi2002]

请教:
能不能把一个表格内的<td>一次性清空，
可不能清空我的<th>呵

[flashsoft2000]

tablename.all.tags("TD")

[meizz]

<table border=1>
<tr><th>abc</th><th>defg</th></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
</table>
<input type=button value=clear onclick=cc()>

<script language=javascript>
function cc()
{
var a = document.getElementsByTagName("td");
for(var i=0; i<a.length; i++)
a[i].innerHTML = "";
}
</script>

meizz(梅花雨) :一个指定表格的.
不是把所有表格的怎么做呵

[meizz]

<table border=1 id=table1>
<tr><th>abc</th><th>defg</th></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
</table>
<input type=button value=clear onclick=cc()>

<table border=1>
<tr><th>abc</th><th>defg</th></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
</table>

<script language=javascript>
function cc()
{
var a = document.all.table1.getElementsByTagName("td");
for(var i=0; i<a.length; i++)
a[i].innerHTML = "";
}
</script>

to meizz(梅花雨):
当这样操作之后,
表格还有残留的边线如何去掉?

[meizz]

你到底是要清空TD里的内容还是连TD都清掉.
若只是清除TD里的内容,那上面的例子已经可行了.
若是连TD也要拿掉的话,你将 a[i].innerHTML 改成 a[i].outerHTML 即可.

那是因为tr没去除的原因
<table border=1 id=table1>
<tr><th>abc</th><th>defg</th></tr>
<tr></tr>
<tr></tr>
<tr></tr>
<tr></tr>
</table>

[flashsoft2000]

清除tr就可以

想哭,还是不行
<table border=1 id=table1>
<tr><th>abc</th><th>defg</th></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
</table>
<input type=button value=clear onclick=cc()>

<table border=1>
<tr><th>abc</th><th>defg</th></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
<tr><td>aaa</td><td>bbbb</td></tr>
</table>

<script language=javascript>
function cc()
{
var a = document.all.table1.getElementsByTagName("td");
for(var i=0; i<a.length; i++)
a[i].outerHTML ="";
}
</script>
