高分请高手补充JavaScript源代码---(50分)

用数字来命名控件不是个好办法，但试试<script langugage="javascript">
function document.onclick()
{
  var ele = event.srcElement;
  if (ele.tagName == "INPUT" && ele.type == "checkbox")
  {
switch (ele.name)
{
   case "all":
setCheck(ele,true);
break;
   case "1": case "2": case "3": case "4":
setCheck(ele);
break;
   default:
break; }
  }
}function setCheck(obj, bAll)
{
  var inputs = document.all.tags("INPUT");
  for (var i=0; i < inputs.length; i++)
  {
if (inputs[i].type == "checkbox" && obj != inputs[i])
{
  if (bAll)
inputs[i].checked = obj.checked;
  else if (inputs[i].name.length > 1 && inputs[i].name.indexOf(obj.name) ==0)
inputs[i].checked = obj.checked; }

  }
}
</script>

第一个选择做好啦,是不是这样?下面依次类推:<script>
function qi(all){
for(i=0;i<list1.checkbox1.length;i++)
list1.checkbox1[i].checked=all;}
</script><FORM name="list1" METHOD=POST ACTION="">
<INPUT TYPE="checkbox" NAME="1" value="Check All" onClick="qi(this.checked);">1

会出错。就是选择第14时，前面的也会自动被选中。可否请你帮我更改.不够可以加分
<script langugage="javascript">
function document.onclick()
{
  var ele = event.srcElement;
  if (ele.tagName == "INPUT" && ele.type == "checkbox")
  {
switch (ele.name)
{
   case "all":
setCheck(ele,true);
break;
   case "1": case "2": case "3": case "4":
   case "5": case "6": case "7": case "8":
   case "9": case "10": case "11": case "12":
   case "13": case "14":
setCheck(ele);
break;
   default:
break; }
  }
}function setCheck(obj, bAll)
{
  var inputs = document.all.tags("INPUT");
  for (var i=0; i < inputs.length; i++)
  {
if (inputs[i].type == "checkbox" && obj != inputs[i])
{
  if (bAll)
inputs[i].checked = obj.checked;
  else if (inputs[i].name.length == (obj.name.length + 1) && inputs[i].name.indexOf(obj.name) ==0)
inputs[i].checked = obj.checked; }

  }
}
</script>
这么取名:
ac
  ac1
  ac2
  ac3
  ....
bd
  bd1
  bd2
  bd3
  ....
cx
  cx1
  cx2
  cx3意思就是，父复选框的名字总是与其它父复选框的名字不同，但其子复选框的名字是以父复选框的名字加数字来命名的然后试用这脚本:
<script langugage="javascript">
function document.onclick()
{
  var ele = event.srcElement;
  if (ele.tagName == "INPUT" && ele.type == "checkbox")
  {
        if (ele.name == "all")
          setCheck(ele,true);
else if (!/\d+/.test(ele.name))
  setCheck(ele);
  }
}function setCheck(obj, bAll)
{
  var inputs = document.all.tags("INPUT");
  for (var i=0; i < inputs.length; i++)
  {
if (inputs[i].type == "checkbox" && obj != inputs[i])
{
  if (bAll)
inputs[i].checked = obj.checked;
  else if (inputs[i].name.indexOf(obj.name) ==0)
inputs[i].checked = obj.checked; }

  }
}
</script>
奇怪，怎么不行啊。父复选框的名字这样可以吧：a1a、a2a、a3a、a4a、a5a.....，为了在服务器好取值，所以命名了有一定的规则，你也可以更改。用a1、a2、a3、a3、a4........<script language="javascript">
function document.onclick()
{
  var ele = event.srcElement;
  if (ele.tagName == "INPUT" && ele.type == "checkbox")
  {
        if (ele.name == "all")
          setCheck(ele,true);
else if (!/\d+/.test(ele.name))
  setCheck(ele);
  }
}function setCheck(obj, bAll)
{
  var inputs = document.all.tags("INPUT");
  for (var i=0; i < inputs.length; i++)
  {
if (inputs[i].type == "checkbox" && obj != inputs[i])
{
  if (bAll)
inputs[i].checked = obj.checked;
  else if (inputs[i].name.indexOf(obj.name) ==0)
inputs[i].checked = obj.checked; }

  }
}
