ztree+ajax+json请求，实现加载一棵ztree树

以你之姓@ 2023-01-01 03:49 214阅读 0赞

前面的话：zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。专门适合项目开发,尤其是 树状菜单、树状数据。

ztree官方文档：[http://www.treejs.cn/v3/api.php][http_www.treejs.cn_v3_api.php]

--------------------

现在写了一个小的demo，具体可以参考官方文档，从文档上拿来一串json数据，放在前端的代码里面，方便大家查看效果，以及方便后端返回的数据。

            $(document).ready(function() {

在浏览器里面打开，效果如图所示：

把demo放在了github上面，有需要的可以自行下载;github：[https://github.com/wangxiaoting666/ztree][https_github.com_wangxiaoting666_ztree]

现在如果是把数据放在json里面，通过ajax去请求，动态渲染出来。  
这里的一切插件直接去前面给到的ztree的官方网站上去下载到本地，就可以直接引用了。  
demo如下：

test.json数据  
自己动手，写一些模拟的json数据吧。
