dojo dijit.tree getChildren() 不返回所有树节点

Question

I am using dojo 1.10.4 and have noticed that the dijit.tree getChildren() function only returns children (tree) nodes that are expanded (displayed and visible) in the dijit.tree. How can I loop through all of the dijit.tree tree nodes regardless of whether or not they are displayed and visible?

• I can easily loop through all of the underlying data store elements but I am trying to locate specific tree nodes so that I can style them using "node.labelNode.style".
• I could programmatically expand all of the dijit.tree nodes prior to calling getChildren() but I wish to preserve the user's view of the dijit.tree.

Any suggestions are greatly appreciated.

I'm not sure if this is what you are after, but that's how we are expanding all the nodes, which is similar to your task, getting all the nodes from the tree. I believe with a simple modification you will be able to achieve your task

Assume that we have a function for expanding the tree nodes, which we are going to call

    this._expandTree(this._tree.rootNode);

and the function itself

    _expandTree: function (node) {
                if (node.hasChildren()) {
                    var currentNode;
                    for (var i = 0; i < node.getChildren().length; i++) {
                        currentNode = node.getChildren()[i];                            
                        this._expandTree(currentNode);
                    }
                }
            },
