Get parent node in custom section tree

Question

I have a multi level tree in my custom-section of Umbraco 7, where the root node is always the country.

• Denmark
  • Item 1
  • Item 2
• Sweeden
  • Item 1
  • Item 2
• Norway
  • Item 1
  • Item 2

Now, when working with Item 2 of Denmark, i would like to get the node-ID of the root-node (Denmark) so that i know what Country ID i'm working under.

Is there any JavaScript API to recurse back over the node levels, and get the top-most expanded?

Thanks in advance. Jonas

Answer 1

What I did was to use editorState
(I'm running Umbraco 7.5.7)

angular.module("umbraco").controller("Client.Controller",
  function ($scope, editorState) {

    // Get the rootNode out of the path.
    var rootNode = editorState.current.path.split(",")[1];
});

Since the path contains the entire structure where the current node is located, the second first node would be the root node.

Another solution might be this:
(Haven't tested this myself)
https://our.umbraco.org/forum/developers/extending-umbraco/73796-how-to-get-the-parentid-of-the-current-node-in-custom-tree-using-angularjs

Which in a simple way states:

inject appState and treeService into your angular controller

This will get the top most node of the current tree:
var rootNode = appState.getTreeState("currentRootNode");

This will get the current selected node in the custom tree
var selectedNode = appState.getTreeState("selectedNode");
