Sounds like a bug. I will look into it.

mbraak commented on August 15, 2024

I cannot reproduce the error.

Do you use 'getselectednode' or 'getSelectedNode'?

from jqtree.

this is my code :

function OnStartPage() {
var mydiv = $("#mydiv");

$.getJSON(
        "mypage.aspx",
        function (data) {
            if ("" == mydiv[0].innerHTML) {
                mydiv.tree({
                    data: data,
                    autoOpen: false,
                    dragAndDrop: false,
                    selectable: true,
                    saveState: "mytreeview"
                });
            }
            else {
                mydiv.tree('loadData', data);
            }
        }
);

var node = mydiv.tree('getselectednode');

// result : node is null

}

I think you should call 'getSelectedNode' after loading the data. Like this:

$.getJSON(
        "mypage.aspx",
        function (data) {
            if ("" == mydiv[0].innerHTML) {
                mydiv.tree({
                    data: data,
                    autoOpen: false,
                    dragAndDrop: false,
                    selectable: true,
                    saveState: "mytreeview"
                });
            }
            else {
                mydiv.tree('loadData', data);
            }

            var node = mydiv.tree('getSelectedNode');
        }
);

I hope this works.

medouederni commented on August 15, 2024

from jqtree.

limmouyleng commented on August 15, 2024

I also got problem with 'getSelectedNode' . It returns "false" for the first time of select. But what I prefer is i want to get the node that i select. Any help?

from jqtree.

mbraak commented on August 15, 2024

Hello Limmouyleng,

In which situation exactly does getSelectedNode return false? Are you using the saveState option or are you selecting a node by clicking on it?

Greetings

from jqtree.

Hi mbraak,

I solved this problem by using " $(document).delegate('#tree', 'click', function() {}) " . But the previous problem is when i used "onclick in

" and it returns false for the first click.
