I finally have solved this.
If someone is interested:
1.- I enabled the cookies in tree init:
cookies : {prefix : “tree”},
2.- Now i have the cookie tree_selected wich says me the selected node.
3.- Whe my own ajax function (external to jstree) returns on his “success” y call to this function ChangeSelectedIDValue(newIDvalues)

function ChangeSelectedIDValue(newID)
{
var myID = document.getElementById($.cookie(‘tree_selected’));
myID.setAttribute(‘id’,newID);
}

So, now i have the id value updated

Hi Vakata:
I have see the new Jstree site. Congratulations!
Excuse me for not sending you examples. I have some problem with them. Will work on it ;-).
But now, I have a different problem. Maybe you can help me.
As I say you in other post I save node info in the “id” of the node. When i want to create a new node use oncreate callback to call with ajax to server. Then, I change the node “id”, as you say, with
$(NODE).attr(“id”, data);

The problem is that now, i want to change the node “id” without using the callback functions. Is there posible?
Excuse me if this is a very obvious question, but i´m not a javascript programer.
Thanks in advance!

@Nostrum
What do you put in the head?
And can you show me an example?
I’ll try putting a tag and see what happens.

Excuse me:

I don´t know why my last post has deleted the line about href. I was writing about http://www.w3schools.com/TAGS/tag_base.asp

The line was (I hope let´s see it):

Hi Vakata:

I have a very curious problem.

The tree works now perfectly. I can add nodes, delete nodes, call by ajax to my server and get the answer.
The problem is, when I put in the head:

The tree now fails:
Let´s supose we are working on http://www.mysite.com/tree.
Whe I want to delete a node, the node is deleted, but inmediately the site is redirected to the base href.
The same when i want to create and when i want to rename.

I need to use base href, to write the correct ajax urls in this mode:
$(‘base’).attr(‘href’) + relative_url

Thank you very much in advance.

Hi Vakata:

This works great!
Anyway, I will see metadata jquery plugin. Maybe it is a best way to do it…

Thank you very much.

I am not sure if this is the best way to store data about the nodes (check the metadata jquery plugin – it is integrated in jsTree).
Still – since you are using oncreate and making an AJAX call – use the return data of the server (have the server return the text that you need for the id attribute). For example:
oncreate : function(NODE, REF_NODE, TYPE, TREE_OBJ) { $.get("YOUR_URL_HERE", function (data) { $(NODE).attr("id", data); }); }

Hi Vakata:

I use jsTree as predefined HTML (with UL as you say in your doc).
The tree is working correctly.
I use the id parameter of “li” to pass all information I need. So id=”node_id=10,other_info=info”.

In this way, when i wan´t to create a new node i use oncreate callback to call with ajax to server. In this call I send the parent node id and it works perfectly.

The problem: the new node has not this info in his “li”, so, if i want to delete this new node i can´t find this info and my server don´t know what to do. (The only way to do it is reload all the page to get the all tree well formatted)

The question is: When I create the node, how can i create his “li” with all the info I need. If i can´t generate just this “li” how can i update all the “ul”?

Thank you very much in advance and excuse me for my poor english.

Currently you cannot create in the same level – just select the upper node and then create, after that you can always reselect the original node. I will consider passing an argument for the create function for the next version.

Examples will be up soon with v.0.8.1
