Remove nodes without children.

[Алексей Курдюков]

Hello,

I need to remove nodes and move all children to it's place.

I use code:

ref = $('#tree').fancytree("getTree"),
searchIDs = ref.getSelectedNodes();

searchIDs.forEach(function(node){
 $children = node.children;
 if ($children!==null)node.parent.addChildren($children,node.getNextSibling());
 node.remove();
});

Where #tree is div with ul\li; If Nodes > 1 I have error "Uncaught TypeError: Cannot call method 'addChildren' of null ".

Could you say any solution?
