MVC is a general term. If you want a general answer - sure it's possible. — John Dvorak

If you want your code fixed, please post the code. A live demo of the issue would be nice as well. — John Dvorak

Please, stop referring to "ASP.NET MVC" simply as "MVC". One is a framework, while other is a language-independent design pattern. It's like calling IE - "the internet" — tereško

Alternative solution with incoding framework:

Controller

        [HttpGet]
    public ActionResult ValidatePin()
    {
        return IncJson(new AlertVM(){Message = "Some thing"});
    }

Razor page

@(Html
  .When(JqueryBind.Click)
  .Do()
  .AjaxGet(Url.Action("ValidatePin","Pin"))
  .OnSuccess(dsl => dsl.Utilities.Window.Alert(Selector.Incoding.Data<AlertVM>(r=>r.Message)))
  .AsHtmlAttributes()
  .ToButton("clickme"))

why do you insist not to implement an action method instead of this static method? my second question is what your method actully does? validation something? so how do you pass it to this method?

Think you might want something like this:

public JsonResult ValidatePin(string id) /*id=pin*/
{
    bool result;
    // do something
    return Json(new { IsValid = result, Message = "something" }, JsonRequestBehavior.AllowGet);
}


$.ajax({
                url: '/validatepin/' + pin,
                type: 'POST',
                dataType: 'json',
                data: json,
                contentType: 'application/json; charset=utf-8',
                success: function (data) {

        alert(data.message + '  ' + data.IsValid);
                }
            })
