How to update jstree node values without reload

Question

I have a jstree that I created with the following code:

$(\'#mytree\').jstree({\"core\": { \"data\" : value
                             , \"themes\" : { \"dots\         


        

Answer 1

for deleting the node and reload tree

 $('#mytree').jstree(true).refresh();

for those who need to redraw without restart the tree use

jQuery('#data').jstree(true).refresh(true);
