jquery调用webservice 常用方法（转）

1、编写

  [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 { get; set; }

        public int Age { get; set; }
    }

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">
