• jQuery调用WebService ( 同源调用)


    转自原文 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(" "));                 }             });         });     });     </script> <head>     <body>         <form id="form1" runat="server">             <p>                 <input type="button" id="btnHelloWorld" value="HelloWorld" />             <p>             <p>                 <input type="button" id="btnHello" value="Hello" />             <p>             <p>                 <input type="button" id="btnArray" value="CreateArray" />             <p>             <p>                 <input type="button" id="btnPerson" value="GetPerson" />             <p>         <form>     <body> <html>
