前面的話：zTree 是一個依靠 jQuery 實現的多功能 “樹插件”。優異的性能、靈活的配置、多種功能的組合是 zTree 最大優點。專門適合項目開發,尤其是 樹狀菜單、樹狀數據。
ztree官方文檔：http://www.treejs.cn/v3/api.php
現在寫了一個小的demo，具體可以參考官方文檔，從文檔上拿來一串json數據，放在前端的代碼裏面，方便大家查看效果，以及方便後端返回的數據。

在瀏覽器裏面打開，效果如圖所示：
把demo放在了github上面，有需要的可以自行下載;github：https://github.com/wangxiaoting666/ztree
現在如果是把數據放在json裏面，通過ajax去請求，動態渲染出來。
這裏的一切插件直接去前面給到的ztree的官方網站上去下載到本地，就可以直接引用了。
demo如下：

自己動手，寫一些模擬的json數據吧。
