Question

I’m attempted to add leading zeros to the seconds value and I keep running into errors. I’ve tried a number of selected solutions posted here and can’t seem to make it work.

I’m pulling values from the spans because those values are coming from the database.

var timer = $('.timer');

$('.prev-button,.next-button').hide();

setInterval(function () {

    var m = $('.min', timer),
        s = $('.sec', timer);

    if (m.length == 0 && parseInt(s.html()) <= 0) {
        timer.html('Proceed to the Next Slide');
        $('.prev-button,.next-button').fadeIn();
    }

    if (parseInt(s.html()) <= 0) {
        m.html(parseInt(m.html() - 1));
        s.html(60);
    }

    if (parseInt(s.html()) < 10) {

        $('.sec').prepend(0)

    }


    if (parseInt(m.html()) <= 0) {

        timer.html('Time remaining for this slide - <span class="sec">59</span> seconds')

    }

    s.html(parseInt(s.html() -1));

}, 1000);

I’ve modified your Fiddle to make it work. http://jsfiddle.net/a2uJ2/3/

You should store the time in javascript int vars instead of reading it from the html elements every time. This causes maintainability problem as you are attaching logic to the layout of your html document.

I haven’t fixed all your code but i’ve created two variables that are used to perform the calculations instead.
