如何使TreeView子节点的Check状态与父节点一致？顶者有分！

[zpengenpz]

这段代码是树的代码，能够选择当前节点的check时子节点的状态和父节点一样。
我想加一点功能就是让子节的check为false时，父节点的check为false
但我不懂jscript，不知在哪加
<script type="text/jscript">
function client_OnTreeNodeChecked()
{
var obj = window.event.srcElement;
var treeNodeFound = false;
var checkedState;
if (obj.tagName == "INPUT" && obj.type == "checkbox")
{
var treeNode = obj;
checkedState = treeNode.checked;
do
{
obj = obj.parentElement;
}
while (obj.tagName != "TABLE")
var parentTreeLevel = obj.rows[0].cells.length;
var parentTreeNode = obj.rows[0].cells[0];
var tables = obj.parentElement.getElementsByTagName("TABLE");
var numTables = tables.length
if (numTables >= 1)
{
for (i=0; i < numTables; i++)
{
if (tables[i] == obj)
{
treeNodeFound = true;
i++;
if (i == numTables)
{
return;
}
}
if (treeNodeFound == true)
{
var childTreeLevel = tables[i].rows[0].cells.length;
if (childTreeLevel > parentTreeLevel)
{
var cell = tables[i].rows[0].cells[childTreeLevel - 1];
var inputs = cell.getElementsByTagName("INPUT");
inputs[0].checked = checkedState;
}
else
{
return;
}
}
}
}
}
}
</script>
