Question

i am using MVC c# i have a object with

public class Person
{
        public int TypeId { get; set; }
        public string Code { get; set; }

}

i have a code that retruns JSON object for this object like this

return Json(personCodeStore.GetPersonCodes(id).Select(x=>new {text =x.Code, value =x.TypeId}), JsonRequestBehavior.AllowGet);

how do i add a Indicator to my JSON return data, so that i can check for empty data

$.getJSON('../PersonList?id=1', function (data) {
if (data==????)
{
alert("has data");
}
else
{
alert("is Empty");
}
}

Answer 1

Could you just check for a property you know a Person object would have? Something like this:

if (data.Id) {
  // We got back something with an Id property... probably a Person
} else {
  // What else could we get back?!?
}
