解析dijit.tree中的节点

Question

I'm struggling with a dijit.Tree and I can't find what I need in the dojo documentation...

I want to change the style of a few elements in my tree, according to some conditions.

I am able to identify the elements through a combination of for loops and if evaluations :

itemList = this.tree.model.store._arrayOfAllItems;
for (var index in itemList) {
    item = itemList[index];
    if (item.<property> == ...) {
       ...
       //This is where I want to change the style
       ...
    }
    ...
}

But then, I fail to get the node id to call dojo.addClass(nodeId, newClass).

Am I parsing through the proper list, with the model.store._arrayOfAllItems? Is there a way to parse through the node list instead, and still access the data properties?

Thank you very much for your help!

With Richard's comments, I was able to obtain the result I was looking for. I have added a handler that connects the tree's onOpen event to a method that gets the open node map (from tree._itemNodesMap) and then fetch through the store. For every item in the store, it adjust the css if the id of the item being validated has an associated node in the open node map. It then looks recursively for children.

Thanks Richard for your help!

If you have the id of the node inside the tree, you can use the getNodesByItem function that tree has.

Although if your tree is dynamic and the contents can change, I would suggest writing a function that not only adds to your store but also adds to a class for the node formed in the tree.
