jsTree : How to get IDs of selected nodes to root node in jsTree?

Question

How to get IDs of selected nodes to root node in jsTree?

Assume C is selected node then How can I get All parent IDs of C.

A

• B

  • C

    +C1

    +c2

Following code will return only immediate parent ID: If I selected C then I get only B

 .bind("select_node.jstree", function (event, data) {  
    //`data.rslt.obj` is the jquery extended node that was clicked          
    alert("Selected node = "+ data.rslt.obj.attr("id"));
    alert("Parent of Selected node = "+ data.inst._get_parent(data.rslt.obj).attr("id"))
 });

Output:

Selected node = C

Parent of Selected node = B

Is there any way to get all parent nodes ID i.e. Selected node to root node ?

• How to get all child nodes of selected node in jsTree ?

Any help or guidance in this matter would be appreciated.

Answer 1

Use parents in jQuery to get all parents, filtering out by li because all tree items are li in jstree, try this:

var parents = data.rslt.obj.parents("li");

And for children use children in jQuery, like so:

var children = data.rslt.obj.parent().find('li');

EDIT Using the above, here's how to get all parent and children and put them in all an array for each:

Parents:

var parents = [];
data.rslt.obj.parents("li").each(function () {
    parents.push({ id: $(this).attr("id"), description: $(this).children("a").text() });
});

Children:

var children = [];
data.rslt.obj.find("li").each(function () {
    children.push({ id: $(this).attr("id"), description: $(this).children("a").text() });
});
