asp.net JSON实例
1、创建一个一般处理程序
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Services;using System.Web.Script.Serialization;namespace TestAjax{ /// <summary> /// $codebehindclassname$ 的摘要说明 /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class jSonTest : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; //context.Response.Write("Hello World"); JavaScriptSerializer jss = new JavaScriptSerializer(); string json= jss.Serialize(new Person() { Name = "liyang", Age = 25 }); json= jss.Serialize(new string[] {"核武器","好" }); Person[] persons = new Person[] { new Person(){Name ="liyang",Age=25}, new Person(){Name="lisi",Age=20}, new Person(){Name="xiaopihai",Age= 5} }; json = jss.Serialize(persons); context.Response.Write(json); } public bool IsReusable { get { return false; } } public class Person { public string Name { get; set; } public int Age { get; set; } } }}
2、前台页面调用 这里用的是jquery jquery-1.7.2.js 自己下载吧
