首先编写handle处理文件:
using System;
using System.Data;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.IO;
namespace Reflect
{
/// <summary>
/// $codebehindclassname$ 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Handler1 : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
//接受参数name和age
string data = "[{name:\"" + context.Request.QueryString.GetValues("name")[0] + "\",age:" + context.Request.QueryString.GetValues("age")[0] + "},{name:\"zhangsan\",age:23}]";
//构建的json数据
context.Response.Write(data);
}
public bool IsReusable
{
get
{
return true;
}
}
}
}
前台代码:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>jquery获取json数据演示页面</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function getData(){
$("#list").html("");//清空列表中的数据
//发送ajax请求
$.getJSON(
"handler1.ashx",//产生JSON数据的服务端页面
{name:"haha",age:40},//向服务器发出的查询字符串(此参数可选)
//对返回的JSON数据进行处理,本例以列表的形式呈现
function(json){
//循环取json中的数据,并呈现在列表中
$.each(json,function(i){
$("#list").append("<li>name:"+json[i].name+" Age:"+json[i].age+"</li>")
})
})
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Button1" type="button" value="获取数据" onclick="getData()" />
<ul id="list"></ul>
</div>
</form>
</body>
</html>
