我如何从控制器向我的ajax发送一个http？

Question

How can send a Http ok and error to my ajax from the controller? for example a httpstatuscodeokay and httpstatuscodebadrequest because when i put inspect in my browser say impresion.js 304 not modified

 $(document).ready(function () { $("#confirmacion-validar-impresion").click(function (e) { e.preventDefault(); var form = $("form#ValidarImpresion").serializeArray(); $.ajax({ type: "POST", dataType: "json", url: '/FotoCarnet/ValidarImpresion', data: form, success: function (response) { $("#modal-confirmacion-carne-impreso").modal('toggle') timedRefresh(); }, error: function (response) { alert("Carné no impreso") } }); $("#confirmacion-reimprimir-carnet-modal").modal('hide'); window.onbeforeunload = false; }); }); 

  [HttpPost] [ValidateAntiForgeryToken] public ActionResult ValidarImpresion(FormCollection form) { //some query if (queryBeneficiario.Count() > 0) { beneficiario = queryBeneficiario.First(); beneficiario.impreso = true; _dbContext.SaveChanges(); return Json(new {sucess= true , HttpStatusCode.OK}); } else { Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest; return Json(new { success = false }); } } 

 <div class="modal fade" id="confirmacion-reimprimir-carnet-modal" tabindex="-1" role="dialog"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title">Validar Impresion</h4> </div> <div class="modal-body"> <p><h4>El Carné fue impreso correctamente?</h4></p> </div> <div class="modal-footer"> <form id="ValidarImpresion" name="ValidarImpresion" action="#" method="post"> @Html.AntiForgeryToken() <input type="hidden" name="cedula" value="@ViewBag.cedula" /> <button id="confirmacion-validar-impresion" type="submit" class="btn btn-success">Sí</button> <button id="impreso-incorrectamente" type="button" class="btn btn-danger" data-dismiss="modal">No</button> </form> </div> </div> </div> </div>

You can just return HttpStatusCodeResult (like 500) in yor action on error.

[HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult ValidarImpresion(FormCollection form)
        {
   //some query
            if (queryBeneficiario.Count() > 0)
            {
                beneficiario = queryBeneficiario.First();
                beneficiario.impreso = true;
                _dbContext.SaveChanges();
                return Json(new {sucess= true , HttpStatusCode.OK});
            }
            else
            {
                Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;
                return new HttpStatusCodeResult(500);
            }
        }
