Question

I just can not figure this out, or find any docs.

I have a bare-bones JSON:

{
“data”: “node”,
“metadata” : { “content”: “hellooooo” }
}

This gets loaded, but I can not figure out how to write to this field, retrieve this field, and ensure that it is made when a new node is created.

Where are the docs for metadata?

Thanks,
Marco.

I found the answer at http://groups.google.com/group/jstree/browse_thread/thread/28d0c8d3eb2d9f8f

if you’re using JSON and you deliver
your nodes with a metadata like this:

{
"data":  "This is the name of the node",
"metadata": {
     "number": "no1",
     "description": "Description"
  }
}

…you’ll be able to get (and set) the
data like this:

$('div#jstree').jstree(
/*  ...options...  */
).bind('select_node.jstree',
function(e, data){
     alert(  $(data.rslt.obj).data('description') 
 ); });

This works with the newest commit
(rc3/r233). In older versions it uses

$(data.rslt.obj).data("jstree").description 

The last solution worked for me (the default download for now is rc2).
