My countdown timer I want to put on a site is having some issues. Countdown is normal, everything is fine, but at the end of the timer, instead of it to clear the timer and display the end message or a call back, it will rather display the end message by the side while time continues to read in the negative.
Can anyone show me what went wrong?
This is my code:
// Set the date we're counting down to
var countDownDate = new Date("March 31, 2017 09:35:00 PM").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now an the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Output the result in an element with id="demo"
document.getElementById("days").innerHTML = days;
document.getElementById("hours").innerHTML = hours;
document.getElementById("minutes").innerHTML = minutes;
document.getElementById("seconds").innerHTML = seconds;
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("endmessage").innerHTML = "EXPIRED";
}
}, 1000);

Each time the countdown is printed, it should be done only if the difference is greater than 0. So moved that part inside the else condition of your IF. Adjust the date accordingly to test your countdown.
Is it not already the 1st of april? It is counting down to a day already passed as in the 31 of march?
Also, you do not need PM, remove PM and just have 09 or 21 etc. Not AM/PM
<script>
// Set the date we're counting down to
var countDownDate = new Date("April 1, 2017 09:35:00").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now an the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Output the result in an element with id="demo"
document.getElementById("days").innerHTML = days;
document.getElementById("hours").innerHTML = hours;

This counts down to 09:35, today.

Helloooo...I've been tasked with creating a web page that contains a count down clock. I have managed to create the clock with HTML and Javascript but what I am having trouble with is the formatting. The client wants the days, hours and minutes in separate individual circles. Not animated, just plain. I've tried a few things with no results. I thought maybe if I created a separate clock for the Days, hours and minutes, that that would work, but when I do this, the clocks disappear. Would love some advice. Thanks a million.
The code for the clock I used is as follows:
<script>
var countDownDate = new Date("Feb 14, 2021 15:37:25").getTime();
var x = setInterval(function() {
var now = new Date().getTime();
var distance = countDownDate - now;
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m ";
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "We Are Live!";
}
}, 1000);
</script>
The CSS I used is as follows but I can only get that to work when I just have one time from the clock, like just the days for instance.
.demo{
border-radius: 50%;
width: 50px;
height: 50px;
padding: 10px;
background: #fff;
border: 3px solid #000;
color: #000;
text-align: center;
font: 30px cantata;
display: flex; /* or inline-flex */
align-items: center;
justify-content: center;
}
</style>
Just place the hours, minutes, and seconds within their own containers and style them separately, e.g:
<div id="demo">
<span id="hours"/>:
<span id="minutes"/>:
<span id="seconds"/>
</div>
I'm kind of a noob to JS and I'm starting to get used to the basics but I am struggling on passing a variable from within a function that is already in a function.. to another function.
I have looked up scope and I have declared a global variable but when I console log it displays undefined. Here is my code. The project is a bar that shows how long you are into your shift at work in percentage.
I need the percentage variable to be passed out of the timed loop and into the moveLoadingBar Function so that the bar will slowly move up as the day goes on. What am I missing?
const target = 100; //percent
let percentage;
function setup() {
//Set the start point for today at 09:00:00am
let start = new Date();
start.setHours(9, 00, 00);
setInterval(timeConversion, 1000);
function timeConversion() {
//Work out the difference in miliseconds from now to the start point.
let now = new Date();
let distance = now -= start;
// Time calculations for hours, minutes and seconds
let hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
let minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
let seconds = Math.floor((distance % (1000 * 60)) / 1000);
let miliseconds = distance;
//Percentage of day complete **** struggling to pass variable to global variable ****
percentage = (miliseconds / target) * 100
}
}
function moveLoadingBar() {
let loadingBar = document.getElementById("myBar");
let id = setInterval(frame, 1000);
function frame() {
if (percentage >= target) {
clearInterval(id);
} else {
loadingBar.style.width = percentage + "%";
}
}
}
//debugging
setup();
moveLoadingbar();
console.log(percentage);
console.log(target);

JavaScript processes code synchronously. There is only one thread of execution. The function you pass to setTimeout() won't be invoked until the JavaScript call stack is idle. So, after you call setTimeout(), the rest of your code continues to process, all the way down to your console.log() statements at the bottom, but at that point, your timer callback still hasn't run, so you see its current value (undefined) logged.
So, really the problem is that your console.log() statements are running before the asynchronous timer runs. Moving the log into the async function shows you that it's working.
const target = 100; //percent
let percentage;
function setup() {
//Set the start point for today at 09:00:00am
let start = new Date();
start.setHours(9, 00, 00);

moveLoadingbar is nested function inside Setup function. Which you cant access directly,and so it was throwing an error.

I am building a deal page with countdown timer to show how much time is remaining to claim the offer. I have the countdown timer working to show how many days, hours, minutes and seconds are left, but would like to have a visual progress bar under the time that fills up based on the days left.
For example, the offer goes live July 1 and expires July 31. If the user loads the page on July 1, the progress bar would be at 0%. On July 31, the progress bar would be set to 100%.
I am currently using the progress bar styling and HTML code used by Bootstrap 3.
I've been trying to the width style property for "progress-bar" to the days remaining, but have not been able to get them to link up
function getTimeRemaining(endtime) {
var t = Date.parse(endtime) - Date.parse(new Date());
var seconds = Math.floor((t / 1000) % 60);
var minutes = Math.floor((t / 1000 / 60) % 60);
var hours = Math.floor((t / (1000 * 60 * 60)) % 24);
var days = Math.floor(t / (1000 * 60 * 60 * 24));
return {
'total': t,
'days': days,
'hours': hours,
'minutes': minutes,
'seconds': seconds
};
}
function initializeClock(id, endtime) {
var clock = document.getElementById(id);
var daysSpan = clock.querySelector('.days');
var hoursSpan = clock.querySelector('.hours');
var minutesSpan = clock.querySelector('.minutes');
var secondsSpan = clock.querySelector('.seconds');
function updateClock() {
var t = getTimeRemaining(endtime);
daysSpan.innerHTML = t.days;
hoursSpan.innerHTML = ('0' + t.hours).slice(-2);
minutesSpan.innerHTML = ('0' + t.minutes).slice(-2);
secondsSpan.innerHTML = ('0' + t.seconds).slice(-2);
if (t.total <= 0) {clearInterval(timeinterval); } } updateClock(); var timeinterval=setInterval(updateClock, 1000); } var deadline=new Date("july 31, 2019 23:59:59"); initializeClock('clockdiv', deadline);

You can use document.querySelector('.progress-bar') and then use .style.width = 'xx %' to set the width.
I've refactored the code a bit to make it more readable :)
Working example:
function Clock(id, startDate, endDate) {
this.clock = document.getElementById(id);
this.timeEl = this.clock.querySelector('.time');
this.progressEl = this.clock.querySelector('.progress-bar');
this.startDate = startDate;
this.endDate = endDate;
this.updateClock();
this.interval = setInterval(this.updateClock.bind(this), 1000);
}
Clock.prototype.updateClock = function() {
var rem = this.getTimeRemaining();
// Update time element
var duration = [
rem.days,
this.padLeft(rem.hours),
this.padLeft(rem.minutes),
this.padLeft(rem.seconds)
];
this.timeEl.innerHTML = duration.join(":");
// Update progress
var progress = this.getProgress(rem.total);
this.progressEl.style.width = (progress * 100) + "%";
// Clear intervall when done
if(rem.t === 0 && this.interval) {
clearInterval(this.interval);
delete this.interval;
}
};
Clock.prototype.padLeft = function(number) {
return ('0' + number).slice(-2);
};
Clock.prototype.getTimeRemaining = function() {
var t = this.endDate - new Date();
if(t < 0) t = 0;
return {
total: t,
days: Math.floor(t / (1000 * 60 * 60 * 24)),
hours: Math.floor((t / (1000 * 60 * 60)) % 24),
minutes: Math.floor((t / 1000 / 60) % 60),
seconds: Math.floor((t / 1000) % 60)
};
};
Clock.prototype.getProgress = function(remainingTime) {
var totalTime = this.endDate - this.startDate;
return 1 - (remainingTime / totalTime);
};
// Example. Replace startDate and endDate with your dates (30sec for demo)
var startDate = new Date();
var endDate = new Date(Date.now() + 30 * 1000);
new Clock("clockdiv", startDate, endDate);

I have a count down clock on my site but it resets if you clear your browser history. Is there a way to stop this from happening. I found the code on a website that you can download from. I was not expecting it to reset when you clear your browser history. Can this code be modified or would it be better for me to find another code for it.
Thanks

You can save the initial deadline time in localStorage(But this will get cleared on erasing history) and then use that instead of resetting it again on reload, If you want your timer to not reset when clearing data, you will have to maintain a server side state.
You can add this piece of code to the bottom of your script. Instead of initializing new deadline each time, you check whether the deadline has already been initialized and stored in localStorage, if so then fetch the deadline from it. If no, the create the new deadline like you did in your original code and store it in localStorage.
Note that you need to use JSON.stringify and JSON.parse methods if you want to store and later retrieve an object from localStorage because it can only hold strings and default string representation of an object isn't very useful.
This code will not reset the countdown on page reload and you can clean history as well but you can't clear localStorage (cached files and cookies) for it to work.
if (!localStorage.getItem('deadline')) {
const deadline = new Date(Date.parse(new Date()) + 15 * 24 * 60 * 60 * 1000);

See the snippet for full code, but note that it will not work here because localStorage is not accessible on SO. You will need to copy and paste it and test it in your browser.

var t = Date.parse(endtime) - Date.parse(new Date());

Hi i got the countdown timer code from :
https://codepen.io/SitePoint/pen/MwNPVq,
and have modified as :
function getTimeRemaining(endtime) {
var t = Date.parse(endtime) - Date.parse(new Date());
var seconds = Math.floor((t / 1000) % 60);
var minutes = Math.floor((t / 1000 / 60) % 60);
return {
'total': t,
'minutes': minutes,
'seconds': seconds
};
}
function initializeClock(id, endtime) {
var clock = document.getElementById(id);
var minutesSpan = clock.querySelector('.minutes');
var secondsSpan = clock.querySelector('.seconds');
function updateClock() {
var t = getTimeRemaining(endtime);
minutesSpan.innerHTML = ('0' + t.minutes).slice(-2);
secondsSpan.innerHTML = ('0' + t.seconds).slice(-2);
if (t.total <= 0) {
clearInterval(timeinterval);
}
if(t.minutes == 0 && t.seconds ==0) {
console.log('in this func');
deadline = new Date(deadline.getTime() + 10*60000);
}
}
updateClock();
var timeinterval = setInterval(updateClock, 1000);
}
deadline = new Date(Date.parse('Fri Mar 30 2018 17:03:00 GMT+0530'));
initializeClock('clockdiv', deadline);
what change, i have done is, i have checked if minutes and seconds both are 0, then the variable 'deadline' should be updated with new time. The countdown timer works fine but as it hits 0:0, it enters the function and everything stops.
You need to initialize clock again when it hits 0:0 (updated pen)
if (t.minutes == 0 && t.seconds == 0) {
console.log('in this func');
deadline = new Date(deadline.getTime() + 10 * 60000);
initializeClock('clockdiv', deadline); //added this line
}
Demo
function getTimeRemaining(endtime) {
var t = Date.parse(endtime) - Date.parse(new Date());

var hours = Math.floor((t / (1000 * 60 * 60)) % 24);
var days = Math.floor(t / (1000 * 60 * 60 * 24));
return {
'total': t,
'days': days,
'hours': hours,
'minutes': minutes,
'seconds': seconds
};
}
function initializeClock(id, endtime) {
var clock = document.getElementById(id);
var daysSpan = clock.querySelector('.days');
var hoursSpan = clock.querySelector('.hours');

if (t.total <= 0) {
clearInterval(timeinterval);
}
if (t.minutes == 0 && t.seconds == 0) {
console.log('in this func');
deadline = new Date(deadline.getTime() + 10 * 60000);
initializeClock('clockdiv', deadline); //added this line
