Dojo树中的超链接

在dojo校园中有一个树形超链接示例树。他们不可点击。有没有人有可点击链接的dojo实现？您是否能够确定点击了哪个节点/链接？我正在寻找这样做的示例代码。Dojo树中的超链接

以下是来自dojo校园的示例代码。如何使这些链接可点击，以及如何从点击图像实现节点选择？

谢谢。

你可以做一个连接到树上的onClick事件。创建树时，向构造函数添加一个额外的onClick参数，指向具有以下签名的函数：

function myOnClickHandler(item, tree, evt){ 
    //item is the node's DataStore item 
    //I forgot if tree is the whole tree or just the currtent node 
    //evt is the usual event object, with things like mouse position, etc... 

    console.log('clicked a tree'); 
} 

var treeControl = new dijit.Tree({ 
    model: treeModel, 
    showRoot: false, 
    _createTreeNode: function(/*Object*/ args) { 
     var tnode = new dijit._TreeNode(args); 
     tnode.labelNode.innerHTML = args.label; 
     return tnode; 
    }, 
    onClick: myOnclickHandler // THIS LINE // 
}, 
"treeOne");
