selecting the first node and focus after move_node

[kofifus]

Consider https://jsfiddle.net/rsp2s88t/9/

The first call to selectFirst() doesn't work, in the debugger I can see firstNode is false, why ? what is the correct way of getting and selecting the first root node ?

The second problem I have is with the focus disappearing which I think is maybe a bug. To reproduce run the jsfiddle, click on 'Root1' , click 'Del', then try to use the arrow keys.

Thanks !

Here is a fix to the first problem: https://jsfiddle.net/rsp2s88t/10/
You need to listen for the ready.jstree event before starting to work with the tree - in your code you were trying to access a node before it was rendered.

As for the focus - I believe this is because the focused node is moved into a closed node, hence losing focus (jstree can not restore the focus as the node is not visible). I will see if something can be done (aside from focusing the node manually of course).

Best regards,

Thx Ivan,

I managed to solve the focus problem by adding inst.element.focus();

I stil not sure why is that needed, where does the focus go ?

anyways see https://jsfiddle.net/rsp2s88t/11/

I believe I explained what happens to the do focus - the focused node is moved inside a closed parent, so jstree can not restore the focused node (as it is inside a CLOSED parent).

Hi Ivan,

I am seeing a lot of strange behavior and would love some help.

What I'm trying to achieve should be simple, it's a tree with a bin node and when you delete a node it is moved to the bin and the focus (&hover) stays where it used to be (that is move to the prev_dom)

Here is where I got to so far https://jsfiddle.net/rsp2s88t/13/

If you go around selecting and deleting nodes (with del)  and moving around with the keyboard a few times you'll see the blue square around the whole tree and/or the keyboard becomes unresponsive. This is despite me doing select_node and focus()

Any help ?

Thx!

PS I think this is a bug or at least unexpected behavior. One does not expect having to set the focus manually after a move or select operation. Perhaps .children('.jstree-anchor').focus() can be added in the code to move_node or even better to select_node

As I explained earlier - the problem is with moving the node to a closed parent. As an experiment - leave the BIN folder open - you will see that after moving a node inside the opened BIN folder, it will stay focused. In your case you are both moving to a closed folder and wanting to change the focus to a new node - so a line of code is necessary.

I will however think about a general default behavior when focus is lost - like moving the focus to the first node.

Best regards,
Ivan
