how to get list of selected nodes in angular ivh tree view?

I am new this ivh tree, https://github.com/iVantage/angular-ivh-treeview

I have been successfully able to configure this library, however I am not able to get the list of selected nodes, is there a way to get list of selected nodes programmatically?

Solution

  • The easiest way is to use ivhTreeviewBfs to collect selected nodes.

    var selectedNodes = []
ivhTreeviewBfs(myTree, function(node) {
  if(node.selected) {
    selectedNodes.push(node)
  }
})

    Note that you can use ivhTreeviewOptions to get the appropriate "selected" attribute if you want to be fully generic. Also, folks will often want to only collect the top-most selected node for a given tree branch. In this case you can return false in the callback passed to ivhTreeviewBfs and that node's children will not be visited.
