1、编写4种WebService方法
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo 
= WsiProfiles.BasicProfile1_1)]
    [ScriptService]                             
//令WebService成功传入Json参数,并以Json形式返回结果
    [GenerateScriptType(typeof(Person))]        //不是必要,但推荐添加(如果Person里面再嵌套另一个复杂类型,则必要声明)
    [ToolboxItem(false)]
    
public class WebService1 : System.Web.Services.WebService
    {
        
/// <summary>
        
/// 无任何参数
        
/// </summary>
        
/// <returns></returns>
        [WebMethod]
        
public string HelloWorld()
        {
            
return "Hello World";
        }

        
/// <summary>
        
/// 传入参数
        
/// </summary>
        
/// <param name="name"></param>
        
/// <returns></returns>
        [WebMethod]
        
public string Hello(string name)
        {
            
return string.Format("Hello {0}", name);
        }

        
/// <summary>
        
/// 返回泛型列表
        
/// </summary>
        
/// <param name="i"></param>
        
/// <returns></returns>
        [WebMethod]
        
public List<int> CreateArray(int i)
        {
            List
<int> list = new List<int>();

            
while (i >= 0)
            {
                list.Add(i
--);
            }

            
return list;
        }

        
/// <summary>
        
/// 返回复杂类型
        
/// </summary>
        
/// <param name="name"></param>
        
/// <param name="age"></param>
        
/// <returns></returns>
        [WebMethod]
        
public Person GetPerson(string name, int age)
        {
            
return new Person()
            {
                Name 
= name,
                Age 
= age
            };
        }
    }

    
/// <summary>
    
/// 复杂类型
    
/// </summary>
    public class Person
    {
        
public string Name { getset; }

        
public int Age { getset; }
    }

2、编写js调用以上方法

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.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>无标题页</title>
    
<style type="text/css">
    input
    
{
        width
:200px;
    
}
    
</style>

    
<script type="text/javascript" src="jquery-1[1].2.6.min.js"></script>
    
<script type="text/javascript">
    $(
function(){  
      
        
/*
            1、WebService请求类型都为Post,WebService的Url为“[WebServiceUrl]/[WebMethod]”
            2、contentType声明为Json
            3、data要用Json的字符串格式传入
            4、设置了dataType为json后,result就直接为返回的Json对象。

        
*/
        
        
//调用无参数方法
        $("#btnHelloWorld").click(function(){
            $.ajax({
                type: 
"POST",
                contentType:
"application/json",
                url:
"WebService1.asmx/HelloWorld",
                data:
"{}",
                dataType:'json',
                success:
function(result){                    
                    alert(result.d);
                }
            });
        });        
        
        
//传入1个参数
        $("#btnHello").click(function(){
            $.ajax({
                type: 
"POST",
                contentType:
"application/json",
                url:
"WebService1.asmx/Hello",
                data:
"{name:'KiMoGiGi'}",
                dataType:'json',
                success:
function(result){                    
                    alert(result.d);
                }
            });
        });
        
         
//返回泛型列表
        $("#btnArray").click(function(){
            $.ajax({
                type: 
"POST",
                contentType:
"application/json",
                url:
"WebService1.asmx/CreateArray",
                data:
"{i:10}",
                dataType:'json',
                success:
function(result){                    
                    alert(result.d.join(
" | "));
                }
            });
        });
        
         
//返回复杂类型
        $("#btnPerson").click(function(){
            $.ajax({
                type: 
"POST",
                contentType:
"application/json",
                url:
"WebService1.asmx/GetPerson",
                data:
"{name:'KiMoGiGi',age:26}",
                dataType:'json',
                success:
function(result){
                    
var person = result.d;
                    
var showText = [];
                    
for(var p in person){
                        showText.push(p 
+ ":" + person[p]);
                    }
                    alert(showText.join(
"\r\n"));
                }
            });
        });
    });
    
</script>
</head>
    
<body>
        
<form id="form1" runat="server">
            
<p>
                
<input type="button" id="btnHelloWorld" value="HelloWorld" />
            
</p>
