Javascript countdown timer should stop at 00:00

I am working on the countdown timer and I have found this code which pretty much what I need except I dont want to restart the timer when it reaches 00:00. I tried to make changes but wasn't successfull.
Here is the JsFiddle code
<div id="countdown">1:00</div>
var seconds;
var temp;
var GivenTime=document.getElementById('countdown').innerHTML
console.log(GivenTime)
function countdown() {
time = document.getElementById('countdown').innerHTML;
timeArray = time.split(':')
seconds = timeToSeconds(timeArray);
if (seconds == '') {
temp = document.getElementById('countdown');
temp.innerHTML = GivenTime;
time = document.getElementById('countdown').innerHTML;
timeArray = time.split(':')
seconds = timeToSeconds(timeArray);
}
seconds--;
temp = document.getElementById('countdown');
temp.innerHTML= secondsToTime(seconds);
timeoutMyOswego = setTimeout(countdown, 1000);
}
function timeToSeconds(timeArray) {
var minutes = (timeArray[0] * 1);
var seconds = (minutes * 60) + (timeArray[1] * 1);
return seconds;
}
function secondsToTime(secs) {
var hours = Math.floor(secs / (60 * 60));
hours = hours < 10 ? '0' + hours : hours;
var divisor_for_minutes = secs % (60 * 60);
var minutes = Math.floor(divisor_for_minutes / 60);
minutes = minutes < 10 ? '0' + minutes : minutes;
var divisor_for_seconds = divisor_for_minutes % 60;
var seconds = Math.ceil(divisor_for_seconds);
seconds = seconds < 10 ? '0' + seconds : seconds;
return minutes + ':' + seconds;
//hours + ':' +
}
countdown();

You could simply use clearTimeout function in your countdown when it reaches 00:00
Adding this if condition in your countdown is all you need.
if (secondsToTime(seconds) == '00:00') {
clearTimeout(timeoutMyOswego); //stop timer
}
Working Demo:
var seconds;
var temp;
var GivenTime = document.getElementById('countdown').innerHTML
function countdown() {
time = document.getElementById('countdown').innerHTML;
timeArray = time.split(':')
seconds = timeToSeconds(timeArray);
if (seconds == '') {
temp = document.getElementById('countdown');
temp.innerHTML = GivenTime;
time = document.getElementById('countdown').innerHTML;
timeArray = time.split(':')
seconds = timeToSeconds(timeArray);
}
seconds--;
temp = document.getElementById('countdown');
temp.innerHTML = secondsToTime(seconds);
var timeoutMyOswego = setTimeout(countdown, 1000);
if (secondsToTime(seconds) == '00:00') {
clearTimeout(timeoutMyOswego); //stop timer
console.log('Time"s UP')
}
}
function timeToSeconds(timeArray) {
var minutes = (timeArray[0] * 1);
var seconds = (minutes * 60) + (timeArray[1] * 1);
return seconds;
}
function secondsToTime(secs) {
var hours = Math.floor(secs / (60 * 60));
hours = hours < 10 ? '0' + hours : hours;
var divisor_for_minutes = secs % (60 * 60);
var minutes = Math.floor(divisor_for_minutes / 60);
minutes = minutes < 10 ? '0' + minutes : minutes;
var divisor_for_seconds = divisor_for_minutes % 60;
var seconds = Math.ceil(divisor_for_seconds);
seconds = seconds < 10 ? '0' + seconds : seconds;
return minutes + ':' + seconds;
//hours + ':' +
}
countdown();
<div id="countdown">00:10</div>

You can try replacing the code which is responsible for restarting the timer.
But doing only that will result in timer going to negative values.
So as #Always Helping suggested, you need to add the code to stop the timer.
var seconds, temp;
var GivenTime = document.getElementById('countdown').innerHTML;
function countdown() {
time = document.getElementById('countdown').innerHTML;
timeArray = time.split(':')
seconds = timeToSeconds(timeArray);
console.log(seconds);
// Do something when the timer is out
if (seconds === 0) {
clearTimeout(timeoutMyOswego);
return;
}
seconds--;
temp = document.getElementById('countdown');
temp.innerHTML = secondsToTime(seconds);
timeoutMyOswego = setTimeout(countdown, 1000);
};
countdown();
function timeToSeconds(timeArray) {
var minutes = (timeArray[0] * 1);
var seconds = (minutes * 60) + (timeArray[1] * 1);
return seconds;
}
function secondsToTime(secs) {
var hours = Math.floor(secs / (60 * 60));
hours = hours < 10 ? '0' + hours : hours;
var divisor_for_minutes = secs % (60 * 60);
var minutes = Math.floor(divisor_for_minutes / 60);
minutes = minutes < 10 ? '0' + minutes : minutes;
var divisor_for_seconds = divisor_for_minutes % 60;
var seconds = Math.ceil(divisor_for_seconds);
seconds = seconds < 10 ? '0' + seconds : seconds;
return minutes + ':' + seconds;
}
<div id="countdown">00:05</div>

Make a JS countdown starts again

I alreay have some code for a countdown, but would like to make it pause for some hours when at 0 (with a text displayed), and then starts again for 14 days.
<script type="text/JavaScript">
var Display=document.getElementById("Counter");
function Countdown() {
var date1 = new Date();
var date2 = new Date ("Oct 20 20:00:00 2017");
var sec = (date2 - date1) / 1000;
var n = 24 * 3600;
if (sec > 0) {
j = Math.floor (sec / n);
h = Math.floor ((sec - (d * n)) / 3600);
mn = Math.floor ((sec - ((d * n + h * 3600))) / 60);
sec = Math.floor (sec - ((d * n + h * 3600 + mn * 60)));
Affiche.innerHTML = "Next game in : " + d +" d "+ h +" h "+ mn +" min "+ sec + " s ";
window.status = "Remaining time : " + d +" d "+ h +" h "+ mn +" min "+ sec + " s ";
}
tCountdown=setTimeout ("Countdown();", 1000);
}
Countdown();
</script>
So to sum up:
1. The countdown reach 0
2. It blocks for 4 hours and display a text ("We are currently playing")
3. It starts again for around 14 days.
I am thinking of something like this to start again the countdown:
var dateX = var date2 + (a length of time around 14 days)
Am I right?
Can I do this only with Javascript?

I broke it up into a bunch of functions so you can reason about it. If you want to test it, you can set the initial seconds in the sec variable to something small, like 10, and then you can also set the second argument in setTimeout to something small, like 10.
<div id="counter"></div>
<script>
// initialize
var first_target_date = new Date ("Oct 20 20:00:00 2017");
var sec = calcSecDiff(new Date(), first_target_date);
var counter = document.getElementById("counter");
var timeout; // we will update this global variable when we want to stop the whole thing
// start the countdown
countdown();
// do it again every second
var interval = setInterval(function(){
countdown();
}, 1000);
function countdown() {
counter.innerHTML = parseTime(sec);
// decrement the second
sec--;
// if we get to 0
if (sec < 0) {
clearInterval(interval);
counter.innerHTML = "We are currently playing";
if (timeout) return; // it's over
var timeout = setTimeout(function(){
sec = daysToSec(14); // reset the seconds to 14 days away
var interval = setInterval(function(){
countdown();
}, 1000);
}, hrsToMs(4)); // wait four hours before counting down again
};
}
// returns days, hours, minutes, and seconds from seconds
// see https://stackoverflow.com/questions/13903897/javascript-return-number-of-days-hours-minutes-seconds-between-two-dates
function parseTime(sec){
// calculate (and subtract) whole days
var days = Math.floor(sec / 86400);
sec -= days * 86400;
// calculate (and subtract) whole hours
var hours = Math.floor(sec / 3600) % 24;
sec -= hours * 3600;
// calculate (and subtract) whole minutes
var minutes = Math.floor(sec / 60) % 60;
sec -= minutes * 60;
// what's left is seconds
var seconds = sec % 60;
return days + " days, " + hours + " hours, " + minutes + " minutes, " + seconds + " seconds";
}
// calculates the difference between two dates in seconds
function calcSecDiff(date1, date2){
return Math.round((date2 - date1) / 1000);
}
// converts hours to milliseconds
function hrsToMs(hrs){
return hrs * 60 * 60 * 1000;
}
// converts days to seconds
function daysToSec(days){
return days * 24 * 60 * 60;
}
</script>

timezone javascript in my timer

I have found a code but i dont know to add timezone . i want to detect the timer from the timezone of the other country like denmark/copenhagen. thank you. this is my code.
<script type="text/javascript">
ElapsedTimeLogger = function(dateElementId, elapsedElementId, hiden, interval) {
var container = $(elapsedElementId);
var time = parseDate($(dateElementId).val());
var interval = interval;
var timer;
function parseDate(dateString) {
var date = new Date(dateString);
return date.getTime();
}
function update() {
var systemTime = new Date().getTime();
elapsedTime = systemTime - time;
container.html(prettyPrintTime(Math.floor(elapsedTime / 1000)));
$(hiden).val(prettyPrintTime(Math.floor(elapsedTime / 1000)));
}
function prettyPrintTime(numSeconds) {
var hours = Math.floor(numSeconds / 3600);
var minutes = Math.floor((numSeconds - (hours * 3600)) / 60);
var seconds = numSeconds - (hours * 3600) - (minutes * 60);
if (hours < 10) hours = "0" + hours;
if (minutes < 10) minutes = "0" + minutes;
if (seconds < 10) seconds = "0" + seconds;
var time = hours + ":" + minutes + ":" + seconds;
return time;
}
this.start = function() {
timer = setInterval(function() {update()}, interval * 1000);
}
this.stop = function() {
clearTimeout(timer);
}
}
$(document).ready(function () {
var timeLogger = new ElapsedTimeLogger("#date", "#elapsed","#stoppedid", 1);
timeLogger.start();
$("#confirm").click(function() { //Stop timer upon clicking the Confirm Button
timeLogger.stop();
});
});
</script>
thank you. i dont know javascript. i know php only. i tried to put
before the code is running. i already save a time from europe/copenhagen. but when the timer is running. it says 6:00:01 abd counting.. but i want to run like this 0:00:01 and counting. and my idea the time from europe and time in my country is 6 hours. i want to run the time from europe not my country. because i save the time from europe using php. see bellow the code for save the time.
date_default_timezone_set("Europe/Copenhagen");
but wont work. i didnt found the solution

Analyzing this code, I rewrote the needed HTML to see what the code do. It's simply creates a counter in format hh:mm:ss and shows on screen, this counter show the time passed since the date informed.
to add the user timezone to reflect in your timer, you just need to recalculate the seconds inside the prettyPrintTime(numSeconds) function before use it to get hours, minutes and seconds.
function prettyPrintTime(numSeconds) {
var tzOffset = new Date().getTimezoneOffset(); // get the timezone in minutes
tzOffset = tzOffset * 60; // convert minutes to seconds
numSeconds -= tzOffset; // recalculate the time using timezone
var hours = Math.floor(numSeconds / 3600);
var minutes = Math.floor((numSeconds - (hours * 3600)) / 60);
var seconds = numSeconds - (hours * 3600) - (minutes * 60);
if (hours < 10) hours = "0" + hours;
if (minutes < 10) minutes = "0" + minutes;
if (seconds < 10) seconds = "0" + seconds;
var time = hours + ":" + minutes + ":" + seconds;
return time;
}
Take a look at the working code:
https://jsfiddle.net/4c6xdcpr/

function getClientTimeZone() {
var offset = new Date().getTimezoneOffset(),
o = Math.abs(offset);
return (offset < 0 ? "+" : "-") + ("00" + Math.floor(o / 60)).slice(-2) + ":" + ("00" + (o % 60)).slice(-2);
}
// Display Output
alert(getClientTimeZone());

Countdown Timer Problems

I have been looking for a count down timer on google and can't seem to find one.
I was just wondering if anyone would be able to help.
I got given one but it displays the wrong times.
I want it to display days, hours, minutes and seconds left.
heres what I need the timer on
http://pastebin.com/fQjyRFXw
It already has the timer code there but it's all wrong, any help would be great, thank you
If it's helps here's a snippet of the Java code
var count = <?= $time['a_time'] ?>;
var counter = setInterval(timer, 1000); //1000 will* run it every 1 second
function timer() {
count = count - 1;
if(count == -1) {
clearInterval(counter);
return;
}
var seconds = count % 60;
var minutes = Math.floor(count / 60);
var hours = Math.floor(minutes / 60);
minutes %= 60;
hours %= 60;
document.getElementById("clock").innerHTML = hours + "hours " + minutes + "minutes and " + seconds + " seconds left";
}

Ok I see your problem. The a_time stored in database is an Unix timestamp, thus when you are counting down, you need to know how long is between now and a_time instead of only a_time.
Try this:
var count = <?= $time['a_time'] ?>;
var now = Math.floor(new Date().getTime() / 1000);
count = count - now;
var counter = setInterval(timer, 1000); //1000 will* run it every 1 second
function timer() {
count = count - 1;
if(count == -1) {
clearInterval(counter);
return;
}
var seconds = count % 60;
var minutes = Math.floor(count / 60);
var hours = Math.floor(minutes / 60);
var days = Math.floor(hours / 24);
minutes %= 60;
hours %= 24;
document.getElementById("clock").innerHTML = days + "days " + hours + "hours " + minutes + "minutes and " + seconds + " seconds left";
}

Why not use one of the man examples on codepen such as this beautiful one
http://codepen.io/anon/pen/VeLWdz ?
(function (e) {
e.fn.countdown = function (t, n) {
function i() {
eventDate = Date.parse(r.date) / 1e3;
currentDate = Math.floor(e.now() / 1e3);
if (eventDate <= currentDate) {
n.call(this);
clearInterval(interval)
}
seconds = eventDate - currentDate;
days = Math.floor(seconds / 86400);
seconds -= days * 60 * 60 * 24;
hours = Math.floor(seconds / 3600);
seconds -= hours * 60 * 60;
minutes = Math.floor(seconds / 60);
seconds -= minutes * 60;
days == 1 ? thisEl.find(".timeRefDays").text("day") : thisEl.find(".timeRefDays").text("days");
hours == 1 ? thisEl.find(".timeRefHours").text("hour") : thisEl.find(".timeRefHours").text("hours");
minutes == 1 ? thisEl.find(".timeRefMinutes").text("minute") : thisEl.find(".timeRefMinutes").text("minutes");
seconds == 1 ? thisEl.find(".timeRefSeconds").text("second") : thisEl.find(".timeRefSeconds").text("seconds");
if (r["format"] == "on") {
days = String(days).length >= 2 ? days : "0" + days;
hours = String(hours).length >= 2 ? hours : "0" + hours;
minutes = String(minutes).length >= 2 ? minutes : "0" + minutes;
seconds = String(seconds).length >= 2 ? seconds : "0" + seconds
}
if (!isNaN(eventDate)) {
thisEl.find(".days").text(days);
thisEl.find(".hours").text(hours);
thisEl.find(".minutes").text(minutes);
thisEl.find(".seconds").text(seconds)
} else {
alert("Invalid date. Example: 30 Tuesday 2013 15:50:00");
clearInterval(interval)
}
}
var thisEl = e(this);
var r = {
date: null,
format: null
};
t && e.extend(r, t);
i();
interval = setInterval(i, 1e3)
}
})(jQuery);
$(document).ready(function () {
function e() {
var e = new Date;
e.setDate(e.getDate() + 60);
dd = e.getDate();
mm = e.getMonth() + 1;
y = e.getFullYear();
futureFormattedDate = mm + "/" + dd + "/" + y;
return futureFormattedDate
}
$("#countdown").countdown({
date: "1 April 2017 09:00:00", // Change this to your desired date to countdown to
format: "on"
});
});

Why is this JavaScript timer crashing my web page?

So I'm trying to put together a timer to count down to a specific time on a specific day. I found some code to work with online and adapted it to this
var Timer;
var TotalSeconds;
function CreateTimer(TimerID, Time)
{
Timer = document.getElementByID(TimerID);
TotalSeconds = Time;
UpdateTimer()
window.setTimeout("Tick()", 1000);
}
window.setTimeout("Tick()", 1000);
function Tick()
{
if (TotalSeconds <= 0)
{
alert("Time's up!")
return;
}
TotalSeconds -= 1;
UpdateTimer()
window.setTimeout("Tick()", 1000);
}
function UpdateTimer()
{
var Seconds = TotalSeconds;
var Days = Math.floor(Seconds / 86400);
Seconds -= Days * 86400;
var Hours = Math.floor(Seconds / 3600);
Seconds -= Hours * (3600);
var Minutes = Math.floor(Seconds / 60);
Seconds -= Minutes * (60);
var TimeStr = ((Days > 0) ? Days + " days " : "") + LeadingZero(Hours) + ":" + LeadingZero(Minutes) + ":" + LeadingZero(Seconds)
Timer.innerHTML = TimeStr + " until my birthday!";
}
function LeadingZero(Time)
{
return (Time < 10) ? "0" + Time : + Time;
}
When I start it up on my web page it crashes the page. I know the problem is not how I link it to the HTML because I tested this code on http://writecodeonline.com/javascript/ and it did not work there either. Any advice?
