Javascript Countdown

by

Something like this should do the trick. I’m bored and decided to do it myself instead of Googling. Just set the minutes and seconds at the top and change the call to countdown inside the onload to the id of the element you want it to update.

    var interval;
    var minutes = 1;
    var seconds = 5;
    window.onload = function() {
        countdown('countdown');
    }

    function countdown(element) {
        interval = setInterval(function() {
            var el = document.getElementById(element);
            if(seconds == 0) {
                if(minutes == 0) {
                    el.innerHTML = "countdown's over!";                    
                    clearInterval(interval);
                    return;
                } else {
                    minutes--;
                    seconds = 60;
                }
            }
            if(minutes > 0) {
                var minute_text = minutes + (minutes > 1 ? ' minutes' : ' minute');
            } else {
                var minute_text="";
            }
            var second_text = seconds > 1 ? 'seconds' : 'second';
            el.innerHTML = minute_text + ' ' + seconds + ' ' + second_text + ' remaining';
            seconds--;
        }, 1000);
    }
    </script>
</head>
<body>
<div id='countdown'></div>
