Getting the parent node

[Randy Hompesch]

Hi, 
I must be missing something.
if I have a treeview and I have a select event handler bound to it, I can inspect the currently selected node's text by saying e.node.text(). However, if I try to get the text of the parent node, i.e. e.node.parent().text(), I get a string with all the node's text concatenated together. All I want is a simple node.getParent function that returns the exact same object as e.node only it's parent. If the node has no parent (i.e. it s a root), then it should return null. This seems harder than it should be.
Is there a way to do this or am I missing something?
Thanks ... Ed

Hello Randy,

You can use the treeview.text method in order to get the text of a node, and the treeview.parent method to get the parent node.

The harder way of getting the text is caused by the rendering of the treeview -- since the parent method returns a list item (which is the actual item), calling the jQuery .text() method will return the text of all nested elements, too. If you want to stick to jQuery, get the text of the first k-in element.

This seems highly unreliable to me.
What if there are two (or more) nodes with the same text on different branches of the tree?
I need to be sure that I'm getting the correct parent.
Using var parent = treeview.parent(treeview.findByText("bar"));
seems risky to me.
Am I missing something?
Thanks ... Ed

Hello Randy,

Since you already have the node in the event handler arguments, you can use it (instead of searching the treeview):

function onSelect(e) {
     var parent = this.parent(e.node); // `this` refers to the treeview object
     var parentText = this.text(parent);
}
