【100分】怎么给asp:TreeView控件里的CheckBox的Value赋值，让前台JS可以取到？
如题，页面里有个TreeView控件，其中给每个节点都进行了赋值
TreeNode tempnode = new TreeNode();
tempnode.ShowCheckBox = true;
tempnode.Text = IS.Cate_Name;
tempnode.Expanded = false;
tempnode.Value = IS.Cate_ID;
我在前台：
function checkvalue() {
{
var tree = document.getElementById("treeIS");
var inputs = tree.getElementsByTagName("INPUT");
for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "checkbox" && inputs[i].checked) {
alert(inputs[i].text + " " + inputs[i].value);
}
}
}
}
但是在前台可以找到选中的CheckBox，但是没有给value赋值，只有：<input type="checkbox" name="treeISn1CheckBox" id="treeISn1CheckBox" />
因此我用JS就无法取到，谁有什么好办法？？？？

alert(inputs[i].nextSibling.innerHTML)
[解决办法]
var tree = document.getElementById("treeview1");
var inputs = tree.getElementsByTagName("INPUT");
for(var i=0;i<inputs.length;i++)
{
if(inputs[i].type=="checkbox" && inputs[i].checked)
{
alert(inputs[i].text + " " + inputs[i].value);
}
}
或
function ShowCheckbox()
{
var TreeView = " <%=TreeView1.ClientID %> "
var checkNode = document.getElementById( "CheckedNode ")
var checkboxs = document.getElementById(TreeView).getElementsByTagName( "INPUT ")
for(i=0;i <checkboxs.length;i++)
{
if(checkboxs[i].type=="checkbox"&&checkboxs[i].checked )
{
s =checkboxs[i].nextSibling.href
if(s.indexOf( "\\ ") == -1)
{
s=s.substr(0,s.lastIndexOf( " ' "))
s=s.substr(s.lastIndexOf( " ' ")+2)
}
else
{
s=s.substr(s.lastIndexOf("\\")+1,s.lastIndexOf("'")- s.lastIndexOf( "\\ ")-1)
}
checkNode.value+=s+", "
}
}
}

sorry 刚才没仔细调
