I want to add the count-up timer which will count from specified time.
I want to do this as follows:
I would add the button "reset" and after it's clicked the timer starts and counts forever from that specified time, but if I press it again in the future it counts time from that specified time in the future.
var countDownDate = new Date();
// 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.getTime() + 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("demo").innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}, 1000);
I have code like this but the output is very wrong.
Here is the link: JSFiddle
Use localStorage to save the date
var countDownDate = localStorage.getItem('startDate');
if (countDownDate) {
countDownDate = new Date(countDownDate);
} else {
countDownDate = new Date();
localStorage.setItem('startDate', countDownDate);
}
// 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 = now - countDownDate.getTime();
// 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("demo").innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}, 1000);

I took some JS code from w3 to create a countdown. (https://www.w3schools.com/howto/howto_js_countdown.asp)
Because I want to display the countdown multiple times on one page I changed the getElementById("demo") to > getElementsByClassName("demo")
Unfortunately, this doesn't work. Nothing shows up. Why is that and how can I display the same counter multiple times? I tried some things but nothing worked out. This is my code:
html
<p class="demo"></p>
js
// Set the date we're counting down to
var countDownDate = new Date("Jan 5, 2022 15:37:25").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the distance between now and 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.getElementsByClassName("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementsByClassName("demo").innerHTML = "EXPIRED";
}
}, 1000);
As #ShanieMoonlight mentioned you need to iterate over the HTMLCollection. You can easily do it with minimal adjustments. E.g. when you use the spread-operator the forEach-function will be available.
// Set the date we're counting down to
var countDownDate = new Date("Jan 5, 2022 15:37:25").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the distance between now and 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.getElementsByClassName("demo")].forEach(e => e.innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ");
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
[...document.getElementsByClassName("demo")].forEach(e=>e.innerHTML = "EXPIRED");
}
}, 1000);

I have implemented the code below in my site, to display a running timer. The site is running on Wordpress. At the moment the date is input in the code (so it applied site wide). I am looking to have a running timer on each post.
I need to change the code below so that I can use a custom field on each post called "expiry" as the date, instead of the hardwired date below (newDate("Jan 5, 2021 15:37:25).getTime()
<!-- Display the countdown timer in an element -->
<p id="demo"></p>
<script>
// Set the date we're counting down to
var countDownDate = new Date("Jan 5, 2021 15:37:25").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the distance between now and 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);
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
</script>
The above code is sourced from here
My site is here
Thanks in advance
below steps is your requirements:
1) in custom field expiry set return format as custom "F j, Y g:i:s"
example link (https://prnt.sc/pqg79l)
2) add this function in functions.php
function functionname() {
global $post;
$field= get_field('expiry_date', $post->ID);
echo '<input type="hidden" id="date" value="'.$field.'">';
}
add_action( 'template_redirect', 'functionname' );
3) in your js file add below script
var $= jQuery;
var d = $("#date").val();
console.log(d);
// Set the date we're counting down to
var countDownDate = new Date(d).getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the distance between now and 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);
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
make sure you have to add <p id="demo"></p> where you want to show in post
I have tried this code..It's totally working fine..I hope i have helped you by this
I'm trying to make a count up timer, it has to be counting the time that a ticket is getting solved even if you change or refresh the page, when it is over the user has to click the button stop, but I have a problem, when it is counting I press the button Stop and reset it works but when I refresh my site it is still counting and it doesn't stop.
This is for my site:
var countDownDate = localStorage.getItem('startDate');
if (countDownDate) {
countDownDate = new Date(countDownDate);
} else {
countDownDate = new Date();
localStorage.setItem('startDate', countDownDate);
}
var x = setInterval(function() {
var now = new Date().getTime();
var distance = now - countDownDate.getTime();
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 " + seconds + "s ";
}, 1000);
function Reset() {
var countDownDate = localStorage.getItem('startDate');
if (countDownDate == 0, clearInterval(x)) {
countDownDate = new Date(countDownDate);
} else {
countDownDate = new Date();
localStorage.setItem('startDate', countDownDate);
}
}
<button onclick="Reset()">Stop and Reset</button>
<p id="demo"></p>
I have a working count up timer but it resets everytime I change the page, for example index.php -> help.php -> index.php(and here the timer starts again from 0 instead of counting in the background)
The code is here:
<h1 id="demo"></h1>
countDownDate = new Date(); localStorage.setItem('startDate', countDownDate);
var countDownDate = localStorage.getItem('startDate');
if (countDownDate) {
countDownDate = new Date(countDownDate);
} else {
countDownDate = new Date();
localStorage.setItem('startDate', countDownDate);
}
// 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 = now - countDownDate.getTime();
// 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("demo").innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}, 1000);
In the following code I want to make a text input field (for a date) which gets executed so that the countdown timer is set to that value and starts counting - for example after clicking "OK" button. I don't really know how to modify the first variable in order to do that.
<script>
// Set the date we're counting down to
var countDownDate = new Date("May 25, 2018 11:30:00").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);
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = "Pozostało: </br>" + days + " Dni, </br>" + hours + "g : " + minutes + "m : " + seconds + "s";
document.getElementById("demo").style.fontSize = "45px";
document.getElementById("demo").style.fontWeight = "bold";
document.getElementById("demo").style.color = "white";
document.getElementById("demo").style.backgroundColor = "#4783bf";
document.getElementById("demo").style.textAlign ="center";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
</script>
Thank you for all the advice!
Have a look at this fiddle start timer on click of button
I have entered this date in textbox :- May 26, 2017 01:30:00
function startTimer(){
var dateEntered = document.getElementById("txtDate").value;
// Set the date we're counting down to
//May 26, 2017 01:30:00
var countDownDate = new Date(dateEntered).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;

The first, you need to download datetimepicker library.
https://plugins.jquery.com/datetimepicker/
And then, following this. Remember to change the path of css and jquery files.
<link href="~/css/jquery.datetimepicker.css" rel="stylesheet" />
<body>
<input type="text" id="datetimepicker" />
<input type="button" value="Ok" id="btOk" />
<p id="demo" />
</body>
<script src="~/lib/jquery/dist/jquery.js"></script>
<script src="~/js/jquery.datetimepicker.min.js"></script>
<script type="text/javascript">
$('#datetimepicker').datetimepicker();
$(document).ready(function () {
$('#btOk').click(function () {
var currentDate = $('#datetimepicker').val();
var countDownDate = new Date(currentDate).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);
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = "Pozostało: </br>" + days + " Dni, </br>" + hours + "g : " + minutes + "m : " + seconds + "s";
document.getElementById("demo").style.fontSize = "45px";
document.getElementById("demo").style.fontWeight = "bold";
document.getElementById("demo").style.color = "white";
document.getElementById("demo").style.backgroundColor = "#4783bf";
document.getElementById("demo").style.textAlign = "center";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
});
});
