Topic: Whether has sense regular Submit HTML forms in 2016?
Actually, earlier for sending of the data of the form it was always used regular Submit. I.e. fill fields <input type = forms with the data, then or the button or JS the form on the server. Under it Web-frejmvorki server ( the given fields and so forth), on it as old ASP.Net and MVC. Now all becomes through great and mighty JS XMLHttpRequest. It is possible to tell that all old paradigms and go on . Here on RSDN still in the old manner the form if the site became inaccessible - after pushing the button page of an error and it is lost all data which typed. And after all if through XMLHttpRequest - that could produce simply an error in a pop-up window, as on all modern sites.
