根节点上的dojo树事件 [英] dojo tree event on root nodes

问题描述

**我正在使用以下代码构建dojo树：

**I'm building dojo tree using the following code:

树按预期显示。我的问题是onClick事件只是在叶节点上被触发。当我单击根级别节点（我有几个根级别）时，它只是显示子节点。

The tree is displayed as expected. The problem that I have is that the onClick event is only fired on leaf nodes. When I click on the root level node(I have several root level) it is just open showing child nodes.

如何将extraonClick功能添加到根目录节点？

How can I add "extra" onClick functionality to the root nodes?

推荐答案

您已经将 openOnClick 设置为true树。我认为API文档也可以这样回答。

You've got openOnClick set to true for your tree. I think the API docs answer this as well as I possibly could.

http://dojotoolkit.org/api/dijit/Tree/openOnClick

这样说，看起来你会是可以连接到 _onClick ，而不用做任何你想要的（只有当$ $ c时，负责调用 onClick 的方法$ c> openOnClick 是假的，反正）。或者，如果你想对私人会员感到有点小罪，那么你自己就是一个 dijit.Tree ，扩展 _onClick 还可以激活您定义为public的另一个功能。

That said, it looks like you'd be able to connect to _onClick instead and do whatever you want (that's the method responsible for calling onClick only when openOnClick is false, anyway). Or, if you wanted to feel a little less guilty about accessing private members, dojo.declare yourself a subclass of dijit.Tree, extending _onClick to also fire another function you define as public.
