Selecting the First/Root Node of a Tree 0rc

[jcb]

I found initially_select and that works fine. But in my case the ID
of the first/root node can change.

A user can destroy and completely recreate the tree. I load nodes via
xml from my database and track parent ID along with the ID.

So initially the first node might have an ID of 1 but after the user
deletes and creates a few trees it might have an ID of 8.

Is there a way to select the first/root node after a refresh?

Hi,

Maybe you should use something like this:

$('#tree_id').jstree('select_node', 'ul > li:first');

Of course, if you're using some LI-nodes inside UL-nodes in another
place on your website, then the jQuery selector should be more
complicated to select first li inside ul, which is in your tree.

Cheers,

Thanks Chris, that works fine when I put it in a clickable anchor.

I'm hoping to have it select the first node after the tree loads.
Like
right after a refresh. I tried:

.bind("loaded.jstree", function (event, data) {
$('#ntree').jstree('select_node', 'ul > li:first');
})

but it didn't work.

Mistyped, this is what I tried.

.bind("loaded.jstree", function (event, data) {

data.inst.select_node('ul > li:first');
})

Try binding to "reselect.jstree" instead :) Sorry about that :)

Worked like a charm!

9 years later, and this worked perfectly! (maintaining and old jstree version)
