How to prevent form from submitting multiple times from client side?

Validation prevent form submitting ? Or must i use ever js ?

Code:

prevent  with js
function () {
$("#personal_information").submit(function (e) {
e.preventDefault();

var url = $(this).attr('action');
var postData = $(this).serialize();


$.post(url,
postData
,
function (data, status) {

var w = JSON.parse(data);
console.log(w);
if (w.result == 1) {

var output = forgotMessageSuccess2(w.message);

var aboutme = document.getElementById("aboutme").value;
document.getElementById("aboutmetext").innerHTML = aboutme;
$("#forgotbanner5").empty();
$("#forgotbanner5").append(output).fadeIn(1000);


timeout('#forgotbanner5');


} else {
var output = forgotMessageFaill2(w.message);


$("#forgotbanner5").empty();
$("#forgotbanner5").append(output).fadeIn(1000);
timeout('#forgotbanner5');

}


});


});

};

disable button after press (use JS)

Disabling the button with JS is good for the client side validation and for UX (user experience). But you can also add a CSRF token to your form to reject the other requests. Only the first one will have a valid token and the other will be rejected. Some people (or bots) disable JS, so it's always a good idea to validate data on the server.
