JQuery在asp.net中三种ajax传值

1）通过webservice，注意去掉注释[System.Web.Script.Services.ScriptService]这行前的注释

2）通过aspx.cs文件中的静态方法

3）通过aspx文件url

WebForm1.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="asp.net.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></title>
    <script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script type="text/javascript">
        function Ws() {
            $.ajax({
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "WebService1.asmx/HelloWorld2",
                data: "{name:'xiaoxiao'}",
                dataType: 'json',
                success: function (result) {
                    alert(result.d);
                }
            });
        }
        function StaticMethod() {
            $.ajax({
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "aspxpage.aspx/SayHello2",
                data: "{name:'xiaoxiao'}",
                dataType: 'json',
                success: function (result) {
                    alert(result.d);
                }
            });

        }
        function FromPage() {
            $.ajax({
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "dataContent.aspx?nowtime='" + new Date() + "'",
                data: "{}",
                dataType: 'html',
                success: function (result) {
                    alert(result);
                }
            });

        }

    </script>
</head>
<body>
    <form id="form1" runat="server">

    <div>
        <input id="Button1" type="button" value="jquery调用WebService" onclick="Ws()" />
    </div>
    <div>
        <input id="Button2" type="button" value="jquery调用aspx页面静态方法" onclick="StaticMethod()" />
    </div>
    <div>
        <input id="Button3" type="button" value="jquery通过page存储值" onclick="FromPage()" />
    </div>
    </form>
</body>
</html>

以上是启动页面,WebForm1.aspx.cs没有代码

---------------------------------------

WebService1.asmx

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace asp.net
{
    /// <summary>
    /// WebService1 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
     [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World"+System.DateTime.Now.ToLongTimeString();
        }

        [WebMethod]
        public string HelloWorld2(string name)
        {
            return "Hello World" + name + System.DateTime.Now.ToLongTimeString();
        }
    }
}

以上是webservice中的代码

------------------------------

aspxpage.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;

namespace asp.net
{
    public partial class aspx页面代替ws : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        [WebMethod]
        public static string SayHello()
        {
            return "Hello";
        }

        [WebMethod]
        public static string SayHello2(string name)
        {
            return "Hello"+name;
        }
    }
}

以上是针对第二条通过aspx.cs中的静态方法注意方法前要加 [WebMethod],aspxpage.aspx页面没代码.

-----------------------------------

dataContent.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;

namespace asp.net
{
    public partial class dataContent : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Clear();
            Page.ViewStateMode = ViewStateMode.Disabled;
            if (Request.QueryString["nowtime"] != null)
            {
                string stime = Request.QueryString["nowtime"].ToString();
                Response.Write(stime);
            }
            Response.Flush();

        }
    }
}

以上是针对第三条用url传值通过aspx页面保存数据。dataContent.aspx页面没有代码.
