一、Jquery向aspx頁面請求數據
前臺頁面JS代碼：
代碼如下:
$("#Button1").bind("click", function () {
$.ajax({
type: "post",
url: "default.aspx",
data: "name=" + $("#Text1").val(),
success: function (result) {
alert(result.msg);
}
});
});

代碼如下:



后臺cs代碼：
代碼如下:
protected void Page_Load(object sender, EventArgs e)
{
if (Request["name"]!=null)
{
Response.ContentType = "text/json";
Response.Write("{\"msg\":\""+Request["name"]+"\"}");//將數據拼湊為Json
Response.End();
}
}

二、Jquery向WebService頁面請求數據
代碼如下:
$("#Button2").bind("click", function () {
$.ajax({
type: "post",
contentType: "application/json",
url: "WebService.asmx/HelloWorld",
data: "{name:'" + $("#Text1").val() + "'}",
datatype: "json",
success: function (result) {
alert(result.d);
}
});
});


WebService代碼
代碼如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
///

/// Summary description for WebService
///

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string HelloWorld( string name) {
return "Hello World"+name;
}
}

三、Jquery向ashx請求數據和向頁面相同
Js代碼：
代碼如下:
$("#Button3").bind("click", function () {
$.ajax({
type: "post",
url: "Handler.ashx",
data: "name=" + $("#Text1").val(),
success: function (result) {
alert(result.msg);
}
});
});

后臺代碼:
代碼如下:
<%@ WebHandler Language="C#" Class="Handler" %>
using System;
using System.Web;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/json";
context.Response.Write("{\"msg\":\"Hello World"+context.Request["name"]+"來自handler.ashx\"}");
context.Response.End();
}
public bool IsReusable {
get {
return false;
}
}
}
