Hi all,
Client Side:

------------
API.getDetails = function (id) {

        return $http.post("webservices/WebService1.asmx/getDetails"
       ,JSON.stringify({ 'm': { id: "123"} })
        
        )
    }
---------

      APIservice.getDetails($scope.id).then(function (data, status, headers, config) {
          console.log(data.data);
          $scope.details = data.data;

      },
      function (data) { console.log(data); alert(data); }

      );

Server Side:

                [WebMethod]
[ScriptMethod( UseHttpGet=false, ResponseFormat = ResponseFormat.Json)]
public void getDetails(lst m)
{
    try
    {
        List<Volumes> l = new List<Volumes>();
        l.Add(new Volumes { name= "TEST123", options = "10", shares = "10", stocks = "10", tickets = "10" });

        JavaScriptSerializer js = new JavaScriptSerializer();
        Context.Response.Clear();
        Context.Response.ContentType = "application/json;charset=utf-8";

       Context.Response.Write(js.Serialize(l));
    }
    catch (Exception ex) { throw ex; }
}

when I call the getDetails method then method call successfully and js.Serialize(l) create correct json but the on client side
angular.js

function fromJson(json) {
  return isString(json)
      ? JSON.parse(json)
      : json;
}

where json has extra {d:null} !!!!!!!!

"[{"mpid":"TEST123","shares":"10","stocks":"10","options":"10","tickets":"10"}]{"d":null}"

but when I remove the ,

JSON.stringify({ 'm': { id: "123"} })

and

lst m

then no error show. But i want pass param as well.


can you tell me where is issue?

Thanks all,
