PS：1.

<div id="menuContent" class="menuContent" style="display: none; position: absolute;">

                        <ul id="treesourceID" class="ztree" style="margin-top: 0; width: 180px; height: 300px;">

                        </ul>

                    </div>

这个div放在末尾form外，position为绝对

2. 在放ztree文件时最好不要改变它原始的文件目录结构

这个可以参照官方demo根据需要修改

PS：1. 如果要异步加载则在setting中添加，异步返回的数据会自动绑定

  async: {

        enable: true,

        url: "/admin/Article/ClassIdTree.aspx",

        dataType: 'json',

        type: 'post',

        autoParam: ["id"]

    }

2. 如果是使用简单的数据类型则simpledata(id,pid)设置为true。弊端：child可能加载错的位置上

  data: {

        simpleData: {

            enable: true

        }

    },
public class TreeNodes

    {

       public int id { get; set; }

       public int pId { get; set; }

       public string name { get; set; }

       public bool open { get; set; }

       public bool nocheck { get; set; }

    }

如果要使用自定义的数据类型则首先将simpledata设置为false

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Newtonsoft.Json;

namespace HuaweiSoftware.IPSP_JCW.CheckEntity

{

    [Serializable]

    public class SectionTreeNode

    {

        [JsonProperty(PropertyName = "id")]

        public int ID { get; set; }

        //[JsonProperty(PropertyName = "pId")]

        //public int PID { get; set; }

        [JsonProperty(PropertyName = "name")]

        public string Name { get; set; }

        /// <summary>

        /// 是否展开

        /// </summary>

        [JsonProperty(PropertyName = "open")]

        public bool Open { get; set; }

        /// <summary>

        /// 是否勾选

        /// </summary>

        [JsonProperty(PropertyName = "checked")]

        public bool Checked { get; set; }

        /// <summary>

        /// 不可选

        /// </summary>

        [JsonProperty(PropertyName = "nocheck")]

        public bool Nocheck { get; set; }

         [JsonProperty(PropertyName = "children")]

        public List<SectionTreeNode> Children { get; set; }

    }

}

CS逻辑

 public partial class ArticleTree : System.Web.UI.Page

    {

        ArticleMoveBLL articleMoveBLL = new ArticleMoveBLL();

        protected void Page_Load(object sender, EventArgs e)

        {

            int classId;

            if (Request.Form["articleId"] != null)

            {

                classId = Convert.ToInt32(Request.Form["articleId"].ToString());

                 IList<TreeNodes> articleNodes =  articleMoveBLL.GetArticleByClassId(classId);

            string json = JsonConvert.SerializeObject(articleNodes);

            Response.Write(json);

            Response.End();

            }

        }

    }

这里只要注意一点就是返回json数据
