[Solved] Don’t let a user type the period character in an HTML5 input type number

The definite answer is this:

function preventDot(e) {
            var key = e.charCode ? e.charCode : e.keyCode;

            if (key == 46) {
                e.preventDefault();
            }
        }

And bind it on keypress
