PS：1.

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

                        </ul>
                    </div>

View Code

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"]
    }

View Code

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
        }
    },

View Code

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; }
    }

View Code

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; }
    }
}

View Code

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
