CSDN这个梅花雪树不错。如果自己写着玩，随便一个都可以。但要是数据量很大时，可以看下CSDN这个树

我有源代码。是我自己写的。。也封装了JS。。你要么？ QQ526673470 我现在在网吧，你加我吧，我到时候发给你。

http://topic.csdn.net/u/20100827/11/3a2fb67a-ae8d-4914-8bf4-3c27723feab3.html在这里。你看看吧。。有我发的代码。。我忘记了。呵呵

alert("学习了！不过，这个不是那种可以点击收回的呀！")

<a href="#" id="productsActuator" class="actuator">根节点</a>
这个是亮点

调试易
