A simple countdown timer in Javascript
/********************************************************************************************************************
Countdown.js is a simple script to add a countdown timer
for your website. Currently it can only do full minutes
and partial minutes aren't supported. This script is a fork of http://jsfiddle.net/HRrYG/ with some
added extensions. Since the original code that I forked was released under Creative Commons by SA license,
I have to release this code under the same license. You can view a live demo of this code at http://jsfiddle.net/JmrQE/2/.
********************************************************************************************************************/
function countdown(minutes) {
var seconds = 60;
var mins = minutes
function tick() {
//This script expects an element with an ID = "counter". You can change that to what ever you want.
var counter = document.getElementById("counter");
var current_minutes = mins-1
seconds--;
counter.innerHTML = current_minutes.toString() + ":" + (seconds < 10 ? "0" : "") + String(seconds);
if( seconds > 0 ) {
setTimeout(tick, 1000);
} else {
if(mins > 1){
countdown(mins-1);
}
}
}
tick();
}
//You can use this script with a call to onclick, onblur or any other attribute you would like to use.
countdown(n);//where n is the number of minutes required.

3 minute countdown jumps from 01 to 59 seconds on each iteration.

Amended line 20 as below to count the 00 seconds with a 1000ms timeout

setTimeout(function(){
if(mins > 1){
countdown(mins-1);
}
},1000);

Your code wasn't verbose. It was easy to understand. Thanks for your work!
It was a great help for my project.
I actually forked your snippet in my gist, modified the coding a little bit for my app and want to share with others.
my version countdown
