Galera,
Good afternoon,
A Doubt,
I'm using JsTree and I need some help.
When I select child nodes: 
I can get the same through the script:
$('#arvore').jstree(true).get_selected().
But I can not get the "Parent" nodes (the ones with Square).
Is there a way to return all selected children and parents?
Thank you
I got it,
If anyone needs these "square" nodes, they are called .jstree-undetermined.
To get them, just:
var checked_ids = [];
$("#arvore").find(".jstree-undetermined").each(
function (i, element) {
var nodeId = $(element).closest('.jstree-node').attr("id");
checked_ids.push(nodeId);
}
);
