                   contentType: "application/json; charset=utf-8",
                   url: "http://localhost:4780/WebServiceRegistering.asmx/Registering",
                   data: "{ 'Id': 8 }",
                   contentIype: "application/json",
                   datatype: "json",
                   success: function (data) {
                       alert(data.d);
                   },
                   error: function (data) {
                       alert(" Error aaaaaaa");
                   }
               });

Make sure the ScriptService attribute is added to the webservice

C#

[System.Web.Script.Services.ScriptService]
   public class WebServiceRegistering : System.Web.Services.WebService
