on-demand AJAX loading of json_data not working, please help

[Moishe]

Hi Folks,

I am struggling to get on demand loading of JSON nodes working. The
first call works, but there are two issues:

1) The HTML generated results in leaf icons, even though I have the
state="closed" attribute on all LI tags
2) The call to my service fires only once, on load of the tree, and
never fires again on any clicks

Here is the code:

Property value:

json_data =
{
ajax:
{
type: "GET",
url: AJAXURL,
async: true,
data: function(n) {
// the result is fed to the AJAX request `data` option
var idVal = n.attr ? n.attr("id").replace("node_", "") : -1;
alert("data function called: " + n); // this is only called one
time
return { "operation": "get_children", "id": idVal };
}
},
progressive_render: true,
correct_state: true,
cache: false,
dataType: "json",
error: this.onError,
success: this.onSuccess,
}

Rendered HTML:
<ul>
<li id="1" class="jstree-leaf" rel="root" state="closed">
<ins class="jstree-icon"> </ins>
<a class="" href="#">
</a>
</li>

Types:

"types" : {
"root":
{
valid_children: ["mid", "leaf"]
},
"mid":
{
valid_children: ["mid", "leaf"]
},
"leaf":
{
valid_children: "none"
}
}



JSON content (returned from initial call to web service):

[{ "data": "Accessories", "attr": { "id": "1", "rel": "root", "state":
"closed"} }, { "data": "Inventory", "attr": { "id": "1", "rel":
"root", "state": "closed"} }]


I am using the latest version of jstree.

Thanks for any help!

Hi,

State should be outside attr (on the same level as "data" and "attr")

Cheers,

Thanks Ivan. I'll test it out Monday and respond with the results. I appreciate your quick response!

Hi Ivan,

I changed the JSON as you suggested and it's now working great! What a great plug-in this is.

One more question, how do I get the progress gif to show up during the AJAX call?

jstree automatically shows a spinner when a node is loading.
As for a global page gif - just use the jquery global ajax events, to
bind to ajax start and ajax stop, and toggle a progressbar if needed.

Kindest regards,
Ivan

Thanks Ivan. All is well, the tree is working great, and the customer
