jquery调用webservice 常用方法

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 >
