Avoiding Duplicate form submission in Asp.net MVC by clicking submit twice

I don't think this is quite a duplicate of the answer referenced in the comment, since the link is for spring MVC, and this question is for .NET MVC.

I actually spent a few hours on this a while back, and came up with the following. This javascript hooks nicely with the unobtrusive jquery validation, and you can apply it to any form that has <input type="submit". Note that it uses jquery 1.7's on function:

$(document).on('invalid-form.validate', 'form', function () {
    var button = $(this).find(':submit');
    setTimeout(function () {
        button.removeAttr('disabled');
    }, 1);
});
$(document).on('submit', 'form', function () {
    var button = $(this).find(':submit');
    setTimeout(function () {
        button.attr('disabled', 'disabled');
    }, 0);
});

The setTimeouts are needed. Otherwise, you could end up with a button that is disabled after clicked even when client-side validation fails. We have this in a global javascript file so that it is automatically applied to all of our forms.

Update 16 Nov 2020 by @seagull :

Replaced selector input[type="submit"] with :submit so it will work with <button type="submit" /> as well

The solution for mvc applications with mvc client side validation should be:

$('form').submit(function () {
    if ($(this).valid()) {
        $(':submit', this).attr('disabled', 'disabled');
    }
});
