Many places have said that only elements with a
name attribute go to the server on page change, and only the element name and its
value attribute's value travel between client & server. Is this a
PHP feature or is it also present in other scripting languages? For example, is this the case with
Node.js, or any of its popular server frameworks like
grunt? Also, are there ways to send other elements or attributes to the server?
I know that
AJAX can cause pretty much anything to go to the server, but this is usually asynchronous, and even when it isn't the info doesn't usually go to the server right when the page is sent. If you have any relevant info on
AJAX, though, please share it.
