jstree select node

Question

Greetings, I am using jsTree to generatate my hierarchical data. JsTree is generated as follows:

$(function() {
$("#industries").tree({
        data: {
            type: "json",
            opts: {
                url: "/Admin/GetIndustries/"
            }
        }
    });
});

it works find and the jsonresult is something like:

[{"attributes":[],"data":{"title":"Adwokaci, Notariusze","id":"1a051101-c3fa-48f2-b2e1-c60d1b67ea22"},"children":[{"attributes":[],"data":{"title":"Kancelarie adwokackie","id":"26d6cff1-3c7f-4a2f-bf5a-422e08127b43"

my question is: how can I save id of selected node in some hidden field? I do something like this:

<script type="text/javascript">
    $("#industries").click(function() {
        var tree = $.tree.reference("industries");
        var t = $.tree.focused(); if (t.selected) t.selected; else alert("Select a node first");
        alert(t.id);

    });

but it does not work. I get in my alert window "undefined". Can someone please help me?

EDIT: I've changed the jstree instance as follows:

$(function() {
$("#industries").tree({
        callback: {
            onselect: function(NODE, TREE_OBJ) {
                    alert(NODE.id);
                }
            },
        data: {
            type: "json",
            opts: {
                url: "/Admin/GetIndustries/"
            }
        }
    });
});

and i get empty alertt

Answer 1

Or just bind the select node:

$("#industries").tree({
        callback: {
            onselect: function(NODE, TREE_OBJ) {
                    alert(NODE.id);
                }
            },
        data: {
            type: "json",
            opts: {
                url: "/Admin/GetIndustries/"
            }
        }
    })
.bind("select_node.jstree", function (NODE, REF_NODE) {
            var a = $.jstree._focused().get_selected();
        }
    });

Try looking at the variable a for the ID, or NODE. I was actually using REF_NODE to get

I did not check all the answers but saw that you didnt select any so decided to post a method that worked for me

 $(function () {
        $("#demo1")
        .bind("select_node.jstree", function (event, data) {
                           var selectedObj = data.rslt.obj;
            alert(selectedObj.attr("id") + selectedObj.attr("data"));
             })

this is if you want the id and the title of the node. hope this helps

You can use it in your bind() function like this:

.bind("check_node.jstree", function(e, data) {
    //console.log(data.rslt.obj.attr(\'id\'));

    if (data.rslt.obj !== undefined && data.rslt.obj.attr(\'id\') !== undefined) {
        jQuery.ajax({
            async: false,
            type: "POST",
            dataType: "json",
            url: "' . Yii::app()->createUrl('adsmanager/adsfields/ajaxappendcategory') . '",
            data: {
                "id" : data.rslt.obj.attr(\'id\'),
                "itemId" : "' . Yii::app()->getRequest()->getParam('id') . '",
            },
            success: function(r) {
                if(r === undefined || r.status === undefined || !r.status) {
                    data.rslt.obj.removeClass(\'jstree-checked\');
                    data.rslt.obj.addClass(\'jstree-unchecked\');
                } else {
                    niceBox(\'ok, checked\');
                }
            }
        });
    }

    return true;
});

The same with uncheck action.
