jQuery调用WebService

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
    {
         ///  
        
///  无任何参数
        
///  
        
///  
        [WebMethod]
         public  string HelloWorld()
        {
             return "Hello World";
        }

         ///  
        
///  传入参数
        
///  
        
///  
        
///  
        [WebMethod]
         public  string Hello( string name)
        {
             return  string.Format("Hello {0}", name);
        }

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

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

             return list;
        }

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

     ///  
    
///  复杂类型
    
///  
     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">
