  • Jquery调用webService的四种方法

    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>
