How to select a specific node programmatically?

Just wanted to chime in here as none of the answers worked for me. What finally DID work was very simple:

$('#someTree').jstree('select_node', 'someNodeId');

Note that I didn’t initialize someNodeId as a jQuery object. It’s just a plain string.

I did this right after a tree was loaded without putting it into a “ready” bind event as it seems to not be necessary.

Hope it saves some one from a few frustrating hours. . .

To hook into the tree after it has been loaded:

.on('loaded.jstree', function() {
    // Do something here...
  });
