WCF和Json致电

我正在开发一个WCF应用程序，并且前端使用JSON来调用Web方法。WCF和Json致电

我有一个数据模型类，如下如下

[DataContract] 
    public class GL_AccMainTypeListItem 
    { 
    [DataMember] 
    public int accMainTypeyNo { get; set; } 
    [DataMember] 
    public string mainType { get; set; } 
    [DataMember] 
    public int startAccNo { get; set; } 
    [DataMember] 
    public int endAccNo { get; set; } 

    }

我的Web方法，并返回上述对象列表。基本上在这里我用存储过程（这些工作得很好）

[OperationContract] 
[WebInvoke(Method = "GET", UriTemplate = "GetDataString/{value}", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] 
public List<GL_AccMainTypeListItem> GL_AccMainType_GetAll() 
{ 

     DataAccessService da = new DataAccessService("usp_GL_AccMainTypeGetAll"); 
     DataTable dt = da.ExecuteDataTable(); 


     var acc = (from row in dt.AsEnumerable() 
        select new GL_AccMainTypeListItem 
        { 
         accMainTypeyNo = Utility.ToInt(row["accMainTypeNo"]), 
         mainType = Utility.ToString(row["mainType"]), 
         startAccNo = Utility.ToInt(row["startAccNo"]), 
         endAccNo = Utility.ToInt(row["endAccNo"]) 

        }); 

     return acc.ToList(); 

}

，并从数据库中获取的数据表，并返回到客户端。我想知道如何使用JQuery在客户端调用此Web服务，并逐行迭代结果集。

 <script src="jquery-1.11.2.js"></script> 
     <script> 
      $(document).ready(function() { 
       $('#btnGetAccountList').click(function() {     
        $.ajax({ 
          //url will be yourclassname.svc/yourmethodname 
          url: 'namespaceofGL_AccMainType_GetAllmethod.svc/GL_AccMainType_GetAll', 
          method: 'Get', 
          contentType: "application/json;charset=utf-8",      
          success: function (data) { 
           //your account detail list will be here. 
          }, 
          error: function (err) { 
           alert(err); 
          } 
         }); 
        }); 
       }); 
      </script>

您必须对该方法进行ajax调用。如：

// Function to call WCF Service  
function CallService() { 
$.ajax({ 
    type: Type, //GET or POST or PUT or DELETE verb 
    url: Url, // Location of the service 
    data: Data, //Data sent to server 
    contentType: ContentType, // content type sent to server 
    dataType: DataType, //Expected data format from server 
    processdata: ProcessData, //True or False 
    success: function(msg) {//On Successfull service call 
     ServiceSucceeded(msg); 
    }, 
    error: ServiceFailed// When Service call fails 
}); 
}
