ztree实现一棵树

前面陆陆续续的写过一些ztree的文章,但调用的是后端的接口,demo拿过去没有办法可以直接查看前端的界面,这就造成了一部分人对此理解的困扰。

jQuery的ztree仿windows文件新建和拖拽效果 https://www.jianshu.com/p/bfa67325719c

ztree实现编辑和删除功能 https://www.jianshu.com/p/95d1df89665f

ztree实现根节点单击事件,显示节点信息 https://www.jianshu.com/p/1e0ca6d8afad

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。

        /*function showIconForTree(treeId, treeNode) {
            return !treeNode.isParent;
        };*/
        $(document).ready(function() {
            $.fn.zTree.init($("#sys"), setting, nodes);
        });
    </script>

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
