Ztree之初涉——简单Ztree的实现

来源：互联网发布：科学数据geodata 编辑：程序博客网时间：2024/05/15 00:14

Ztree可以去官网去下载相应的版本和API，我这里就简单的介绍下它的实现以及因为Ztree的小例子印发的Js问题，稍后我会在博客中写JS的异步问题，

我这里用的是MVC4.0,好了正文开始，上代码

namespace ZtreeDemo.Controllers{    public class HomeController : Controller    {        //        // GET: /Home/        public ActionResult Index()        {            return View();        }        public ActionResult Edit()        {            var list = GetData();            return Json(list, JsonRequestBehavior.AllowGet);        }        [NonAction]        public List<Tree> GetData()        {            List<Tree> tree = new List<Tree>();            tree.Add(new Tree { id = 1, pId = 0, name = "蔬菜", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });            tree.Add(new Tree { id = 2, pId = 0, name = "动物", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });            tree.Add(new Tree { id = 3, pId = 0, name = "人类", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });            tree.Add(new Tree { id = 4, pId = 1, name = "茄子", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });            return tree;        }    }    public class Tree    {        public int id { get; set; }        public int pId { get; set; }        public string name { get; set; }        public string icon { get; set; }    }}

这里我就不在解释了，类等我都没去规划，直接在这里写了，比较方便。接下来是视图代码，视图上我用的是ajax获取数据，

@{    Layout = null;}<!DOCTYPE html><html><head>    <title>ZTREE DEMO - Custom Icon </title>    <meta http-equiv="content-type" content="text/html; charset=UTF-8">    <link href="~/Script/css/demo.css" rel="stylesheet" />    <link href="~/Script/css/zTreeStyle/zTreeStyle.css" rel="stylesheet" />    <script src="~/Script/jquery-1.4.4.min.js"></script>    <script src="~/Script/jquery.ztree.core-3.5.js"></script>    <script type="text/javascript">        var tree;        $(function () {            $.ajax({                type: "Get",                url: "@Url.Action("Edit","Home")",                //async: false,                success: function (data) {                    tree = data;                    $.fn.zTree.init($("#treeDemo"), setting, tree);                }            });        })    var setting = {        data: {            simpleData: {                enable: true            }        }    };    //var zNodes = [    //    { id: 1, pId: 0, name: "展开、折叠 自定义图标不同", open: false, iconOpen: "../Script/css/zTreeStyle/img/diy/1_open.png", iconClose: "../Script/css/zTreeStyle/img/diy/1_close.png" },    //    { id: 11, pId: 1, name: "叶子节点1", icon: "../Script/css/zTreeStyle/img/diy/2.png" },    //    { id: 12, pId: 1, name: "叶子节点2", icon: "../Script/css/zTreeStyle/img/diy/3.png" },    //    { id: 13, pId: 1, name: "叶子节点3", icon: "../Script/css/zTreeStyle/img/diy/5.png" },    //    { id: 2, pId: 0, name: "展开、折叠 自定义图标相同", open: true, icon: "../Script/css/zTreeStyle/img/diy/4.png" },    //    { id: 21, pId: 2, name: "叶子节点1", icon: "../Script/css/zTreeStyle/img/diy/6.png" },    //    { id: 22, pId: 2, name: "叶子节点2", icon: "../Script/css/zTreeStyle/img/diy/7.png" },    //    { id: 23, pId: 2, name: "叶子节点3", icon: "../Script/css/zTreeStyle/img/diy/8.png" },    //    { id: 3, pId: 0, name: "不使用自定义图标", open: true },    //    { id: 31, pId: 3, name: "叶子节点1" },    //    { id: 32, pId: 3, name: "叶子节点2" },    //    { id: 33, pId: 3, name: "叶子节点3" }    //];        //$(document).ready(function () {    //    $.fn.zTree.init($("#treeDemo"), setting, Data);    //});       </script></head><body>    <h1>自定义图标 -- icon 属性</h1>    <h6>[ 文件路径: core/custom_icon.html ]</h6>    <div class="content_wrap">        <div class="zTreeDemoBackground left">            <ul id="treeDemo" class="ztree"></ul>        </div>        <div class="right">            <ul class="info">                <li class="title">                    <h2>1、setting 配置信息说明</h2>                    <ul class="list">                        <li>自定义图标不需要对 setting 进行特殊配置</li>                    </ul>                </li>                <li class="title">                    <h2>2、treeNode 节点数据说明</h2>                    <ul class="list">                        <li>利用 节点数据的 icon / iconOpen / iconClose 属性实现自定义图标</li>                        <li class="highlight_red">详细请参见 API 文档中的相关内容</li>                    </ul>                </li>                <li class="title">                    <h2>3、其他说明</h2>                    <ul class="list">                        <li class="highlight_red">由于时间关系，例子直接采用 png 图片，如果需要解决 ie6 下 png 图片的透明问题，请针对 ie6 制作特殊的 gif 图片或者利用 css filter 解决</li>                    </ul>                </li>            </ul>        </div>    </div></body></html>

好了，这就是一个简单的树形菜单，我之前没用过Ztree,因为明天不用上班，就研究学习下，这只是个入门级的，有时间的话我会规整下Ztree返回Json对应数据格式的通用方法以及扩展Ztree的其他比较好的功能通用方法给大家，基本的效果如下：
