How can I refresh the contents of a jsTree?

Question

I have loaded a jsTree with an AJAX call that returns JSON data. How can I refresh the tree so that it reloads its contents?

Answer 1

var tree = jQuery.jstree._reference("#files");
tree.refresh();

or

var tree = jQuery.jstree._reference("#files");
var currentNode = tree._get_node(null, false);
var parentNode = tree._get_parent(currentNode);
tree.refresh(parentNode);
