findFirst - TypeError

[Sergey Dashko]

Hello.

I'm trying to find node by id using findFirst function like this:

$("#tree").fancytree("getRootNode").findFirst(function(node){node.key == id})

but get this error:

"jquery.fancytree-all-deps.min.js:20 Uncaught TypeError: a.toLowerCase is not a function"

What I'm doing wrong?

I can actually find needed tr using Jquery but how can I access node having that tr?

Thanks in advance,

Sergey

Could you post an jsFiddle or Plunkr that reproduces this?

Here you are http://plnkr.co/edit/WSizav?p=preview

Test button adds new child and then use findFirst to find added child and alert it's title.

May be I'm doing something wrong. Please, help me with this.

Regards,

The problem is here: You do

     var newNode = $("#tree").fancytree("getTree").findFirst(function(node){

          node.key == rand

        })

 but you should do

   var newNode = tree.findFirst(function(node){
          return node.key === rand;
        })

However you don't need this, since the add method already returns it:

    var newNode = parentNode.addChildren({title: "Child" + rand, key: rand, checkbox: true, folder: true});

 

Btw. 

- Keys should be strings (not int)

-  you should use a glyph theme when bootstrap is included. For example skin-bootsrap

- and this does not work:

    var selectedNodes = tree.getSelectedNodes()
    if(selectedNodes === 0){

because getSelectedNodes() returns an array.
