Obtaining the treenode value with Javascript

I'm using a treeview control and storing an 'id' number as the value of each treenode.  I'm trying to use Javascript to loop through all the tree nodes to find the ones that are 'checked' and pull the 'value' or ID number in order to populate another control on the page.  Can anyone tell me how to do this?  We're using VS2008.

Thanks!

This code is setup to capture teh event and do a postback, i;m sure you can edit it to get the value or text.
Add this to teh treeview:

add the onclick event to your treeview:
<asp:TreeView ID="TreeView1" onClick="javascript:postbackOnCheck(event);" runat="server"  ShowCheckBoxes="All">

<script type="text/javascript" language="javascript">
 
function postbackOnCheck(e) 
{ 
var isNav = (window.navigator.appName.toLowerCase().indexOf("netscape")>=0); 
var o; 
if (isNav && e != null) 
o = e.target; 
else 
o = window.event.srcElement; 
if (o.tagName == 'INPUT' && o.type == 'checkbox' 
&& o.name != null && o.name.indexOf('CheckBox') > -1) 
__doPostBack("",""); 
} 
</script>

Open in new window
