在FancyTree中获得焦点节点

Question

I am trying to get the current focused node when a button is clicked.

I've tried calling getFocusNode() in the following function on a click handler.

function deleteFolder() {
    var node = $("#tree").fancytree("getFocusNode");
    console.log(node);
}

Unfortunately I get the following error:

Uncaught Error: no such method 'getFocusNode' for fancytree widget instance

On closer inspection of the documentation it says that the getFocusNode method is yet to be implemented.

Is there any other way that I can retrieve the focused node from an external function?

You may be looking for getActiveNode() :

function deleteFolder() {
    var tree = $("#tree").fancytree("getTree"),
        node = tree.getActiveNode();
    console.log(node);
}
