html - Why do regular form submits POSTing data result in page refreshes? -


The title question asks, what process is there? Why should I use AJAX if I want to add that form asynchargly?

This is the way HTTP was created After this, JavaScript was not ubiquitous and today's form Not powerful in.

Anyway, when you post data to a page (a path), you are issuing a request for a server. The server can respond in a variety of behaviors, the simple "return is some content", whether it be HTML, text, JSON, XML etc. Even the server also has the possibility of returning a redirect, so that you can be sent to a different location.

AJAX has requested this request only to run this request in the background and to hide the fact that the data was submitted to the server and the response was returned from the user's perspective.
