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

1 More easy solution

 .get_path ( node , id_mode )

return the path to a node, either as an array of IDs or as an array of node names. mixed node : This can be a DOM node, jQuery node or selector pointing to an element within the tree, whose path we want.bool id_mode : If set to true IDs are returned instead of the names of the parents. Default is false.

// To get path [ID or Name] from root node to selected node 

var ids = data.inst.get_path('#' + data.rslt.obj.attr('id'),true);

// Returns IDs from root to selected node

var names = data.inst.get_path('#' + data.rslt.obj.attr('id'),false); 

// Returns Name's from root to selected node 

alert("Path [ID or Name] from root node to selected node = ID's = "+ids+" :: Name's = "+names);

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() });
});
