大虾们，帮帮我这个新手吧！复选框问题

<td bgcolor="#99CCFF"> <input type="checkbox" name="checkbox" value="<%= khbh %>"></td>再加上script:document.form1.checkbox.value=khbh就行了。只要checkbox现在的值和它原先配置好的值一样，它就是选中状态。<input type="checkbox" name="checkbox" value="<%= khbh %>">中的value="<%= khbh %>">就是原先配置好的值。代码一个字：乱。

不过建议使用radio一般修改的单条修改比较好，批量修改会比较麻烦！先给你个radio的例子！<HTML>

不知这样做是不是太麻烦了

头晕了～楼主这样的代码还是改改逻辑性不好这样没有人愿意仔细看的：） just an advice

自己统计一下
<input type=checkbox>1
<input type=checkbox>1
<input type=checkbox>1
<input type=checkbox>1
<br>
<input type="button" value="全选" onclick="doCheckBox(1)">
<input type="button" value="全不选" onclick="doCheckBox(2)">
<input type="button" value="反选" onclick="doCheckBox(3)">
<script>
function doCheckBox(iType)
{
//1:全选;2:全不选;3:反选;
for(iIndex=0;iIndex<document.all.length;iIndex++)
{
if(document.all(iIndex).type=="checkbox")
{
switch(iType)
{
case 1:document.all(iIndex).checked=true;break;
case 2:document.all(iIndex).checked=false;break;
case 3:{if(document.all(iIndex).checked==true){document.all(iIndex).checked=false;}else{document.all(iIndex).checked=true;}}break;
}
}
}
}
</script>

还有你所有的checkBox都是<input type="checkbox" name="name" value="checkbox">，name都一样，那你知道到底是哪个checkBox提交吗？，建议把名字命名成有意义的，如果是在循环里面命名成数组形式的。
