一、登陆页面HTML

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.EasyUITest.WebForm1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Login</title>
    <script src="../Scripts/jquery-1.6.min.js" type="text/javascript"></script>
    <script src="../Scripts/jquery.easyui.min.js" type="text/javascript"></script>
    <link href="../Scripts/themes/icon.css" rel="stylesheet" type="text/css" />
    <link href="../Scripts/themes/default/easyui.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript">
        $(function () {
            $("#win").window({
                title: "Login",
                width: 300,
                height: 200,

                modal: true
            });
        });
        function login() {
            var name = $("#txt_name").val();
            var psd = $("#txt_psd").val();

            $.ajax({
                type: "POST",
                dataType: "json",
                url: "Service/login.ashx",
                data: { Method: "Login" },

                },
                error: function () {
                    $.messager.alert("消息", "错误！", "info");
                }
            });
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div id="win" class="easyui-window">
        <table>
            <tr>
                <td>
                    Name:
                </td>
                <td>
                    <input id="txt_name" type="text" />
                </td>
            </tr>
            <tr>
                <td>

            </tr>
            <tr>

            </tr>
        </table>
    </div>
    </form>
</body>
</html>

二、一般处理程序

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Reflection;
using System.Web.SessionState;
using Newtonsoft.Json;

namespace WebApplication1.EasyUITest.Service
{
    /// <summary>
    /// login 的摘要说明
    /// </summary>
    public class login : IHttpHandler, IRequiresSessionState
    {
        HttpRequest Request;
        HttpResponse Response;
        HttpSessionState Session;
        HttpServerUtility Server;
        //HttpCookie Cookie;

        public void ProcessRequest(HttpContext context)
        {
            //不让浏览器缓存
            context.Response.Buffer = true;
            context.Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
            context.Response.AddHeader("pragma", "no-cache");
            context.Response.AddHeader("cache-control", "");
            context.Response.CacheControl = "no-cache";
            context.Response.ContentType = "text/plain";

            Request = context.Request;
            Response = context.Response;
            Session = context.Session;
            Server = context.Server;

            string method = Request["Method"].ToString();
            MethodInfo methodInfo = this.GetType().GetMethod(method);
            methodInfo.Invoke(this, null);
        }

        public void Login()
        {
            Response.Write(JsonConvert.SerializeObject(DateTime.Now.ToString()));
        }

        [Serializable]
        public class Infomation
        {
            public string id { get; set; }
            public string msg { get; set; }
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

三、Index页面

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="index.aspx.cs" Inherits="WebApplication1.EasyUITest.index" %>

    <link href="../Scripts/themes/default/easyui.css" rel="stylesheet" type="text/css" />
    <link href="../Scripts/themes/icon.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript">
        $(function () {
            $("#tt").tree({
                checkbox: false,
                url: "Service/index.ashx?Method=GetTreeData&id=0",
                onBeforeExpand: function (node, param) {
                    $(this).tree("options").url = "Service/index.ashx?Method=GetTreeData&id=" + node.id;
                },
                onClick: function (node) {
                    $("#contentPage").attr("src", node.attributes);
                }
            });
        });
        function Open() {
            $("#contentPage").attr("src", "WebForm1.aspx");
        }
    </script>
</head>
<body class="easyui-layout">
    <div region="north" style="height: 100px;">
    </div>
    <div region="west" style="width: 200px;" title="west" split="true">
        <ul id="tt">
        </ul>
    </div>
    <div id="divCenter" region="center" title="center" style="padding: 5px; background: #eee;">
