//option A
$("form").submit(function(e){
e.preventDefault();
});
// BEST OPTION
JUST:
* delete the <button></button> in the friggin FORM and add <a></a> with the same style instead, THE FORM WONT BE SUBMITTED THIS WAY.
* REMOVE THE action="" and method="" tags, and replace them in JQUERY\JS fetch() or $.ajax() functions!
** VOILA **
//option B
$("form").submit(function(e){
e.preventDefault();
});
