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。
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。

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
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：
<!DOCTYPE html> <html> <head> <title>ztree</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <link rel="stylesheet" type="text/css" href="ztree_v3/css/zTreeStyle/zTreeStyle.css" /> <link rel="stylesheet" type="text/css" href="ztree_v3/ztree_custom.css" /> <script src="https://cdn.staticfile.org/jquery/2.1.1/jquery.min.js"></script> <script src="ztree_v3/js/jquery.ztree.core-3.5.min.js"></script> <script src="ztree_v3/js/jquery.ztree.excheck-3.5.min.js"></script> <script src="ztree_v3/js/jquery.ztree.exedit-3.5.min.js"></script> </head> <body> <ul id="zTree" class="ztree" style="background: #0b2b5f;"> </ul> </body> <script type="text/javascript"> //树形菜单 var zTreeObj; //定义ztree对象 initTree(); //初始化ztree var setting = { check: { enable: true, chkStyle: "checkbox", chkboxType: { "Y": "s", "N": "s" } }, view: { selectedMulti: true, showLine: false }, data: { key: { name: "name" }, simpleData: { enable: true, pIdKey: "pId", } }, }; //请求数据 function initTree() { $.get("test.json", function(data) { console.log(JSON.stringify(data)); zTreeObj = $.fn.zTree.init($("#zTree"), setting, data); zTreeObj.expandAll(true); }); } </script> </html>
test.json数据
自己动手，写一些模拟的json数据吧。
[ { "id": 1, "pId": null, "name": "特物联", "iconSkin": null, "checked": null, "isParent": true, "token": null }, { "id": 2, "pId": 1, "name": "管理部", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 157, "pId": 2, "name": "我问问", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 158, "pId": 157, "name": "呜呜呜", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 160, "pId": 158, "name": "热热", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 159, "pId": 2, "name": "热热", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 134, "pId": 1, "name": "研发部", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 140, "pId": 1, "name": "安环部", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 143, "pId": 1, "name": "会议部", "iconSkin": null, "checked": null, "isParent": false, "token": null }, { "id": 152, "pId": 1, "name": "生产部", "iconSkin": null, "checked": null, "isParent": false, "token": null } ]
另外：
往期合集
