javascript to expand all parents of checked nodes?

[Chris]

Trying to create a button that will expand to show all of the checked nodes in the tree...

I can grab a list of all of those nodes, and I think i need to invoke open_node on them but I'm not sure how to do it..

var checkedNodes = $('#jstree').jstree("get_checked", true);

I went with this.  It uses the side effect of opening the node up to the parent, but I didn't like the additional side effect of selecting the node, so it also handles deselecting it if it wasn't already selected.

$('#toggleSelectedButton').click(function () {

        var checkedNodes = $('#jstree').jstree("get_checked", true);

        $.each(checkedNodes, function (index, value) {

            var isSelected = $('#jstree').jstree('is_selected', value);

            $('#jstree').jstree('select_node', value);

            if (!isSelected) {

                $('#jstree').jstree('deselect_node', value);

            }

        });

    });
