Cómo llamo a una función de servidor después de cerrar la pestaña de la ventana o la ventana en JavaScript.
//Este es mi código de servidor
public ActionResult DeleteNotPostedImage(string folder , string PostID) { folder = folder.Replace('_', '-'); string message = string.Empty; try { if (Convert.ToInt32(PostID) <= 0) { if(Directory.Exists(Server.MapPath(string.Format("/ViewSolution/{0}", folder)))) { Directory.Delete(Server.MapPath(string.Format("/ViewSolution/{0}", folder)), true); } } return Json(new { success = true, message = message }, JsonRequestBehavior.AllowGet); } catch (Exception ex) { MSError.Trace(ex); } return Json(new { success = false, message = message }, JsonRequestBehavior.AllowGet); }Quiero llamar a esta función después de cerrar la pestaña del navegador o el navegador.
<script type="text/javascript"> var contentStatus = false; $(document).ready(function () { var checkAction = ""; $('#your-post-btn').bind("click", function () { checkAction = "Save"; $(this).data("clicked", true); }); // on refresh window.onbeforeunload = function(){ if($('#your-post-btn').data('clicked')) { checkAction = "Save"; return null; } else { checkAction = "Refresh"; return "Are you sure to leave this page"; } }; // window close or tab close window.onunload= function(){ if(checkAction.toLowerCase() !== "save"){ Test2(); } }; function Test2(){ console.log(checkAction); var formData = new FormData(); formData.append("folder",folder-name); formData.append("PostID", post-id); formData.append("action", checkAction); var url = window.location.protocol.concat('//',window.location.host) + "/view/DeleteNotPostedImage"; window.navigator.sendBeacon(url, formData); } });
