How can I limit possible inputs in a HTML5 “number” element?

Question

For element, maxlength is not working. How can I restrict the maxlength for that number element?

Answer 1

I had this problem before and I solved it using a combination of html5 number type and jQuery.

script:

$("input[name='minutes']").on('keyup keypress blur change', function(e) {
    //return false if not 0-9
    if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {
       return false;
    }else{
        //limit length but allow backspace so that you can still delete the numbers.
        if( $(this).val().length >= parseInt($(this).attr('maxlength')) && (e.which != 8 && e.which != 0)){
            return false;
        }
    }
});

I don't know if the events are a bit overkill but it solved my problem. JSfiddle
