那么每个input都要加上这个事件么？
晕死！回复错帖子了。
CSDN的系统有问题
<input name="check" type="checkbox" value="<%=i%>" onclick="mm(this)">function mm(e)
{
  e.parentNode.cells[1].childNodes[0].disabled = !e.checked;
}
这里的cells[1]执行的时候有问题，说没有这个对象？请问梅大虾这是怎么回事？
不好意思, 我的代码没有经过测试就放上来了, 改正:
function mm(e)
{
  e.parentNode.parentNode.cells[1].childNodes[0].disabled = !e.checked;
}
