Custom field calculation in wordpress using Javascript - javascript

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

How do I display the date/time for Australia in PHP?

I have this countdown timer that I'm trying to make, but I need to current the current time/date in Australia.
"Clearance Date" is the date I'd like to count down to.
At the moment I'm getting 10d 7h 0m 8s but I believe it should be 9d 21hr
<?php
$clearance_date = 'August 20, 2022 09:00:00';
?>
<p id="demo"></p>
<script>
// Set the date we're counting down to
// 1. JavaScript
// var countDownDate = new Date("Sep 5, 2018 15:37:25").getTime();
// 2. PHP
var countDownDate = <?php echo strtotime($clearance_date) ?> * 1000;
var now = <?php echo time() ?> * 1000;
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
now = now + 1000;
// 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("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.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
</script>
Using PHP to set the date uses the server time. Whereas using now in javascript get the client time.
I would pass the duration (hours left) from PHP to set the javascript variable. And then count that down and add to current date.

JS countdown multiple times on page (won't display with getElementsByClassName)

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);

How to add a specific timezone to a countdown timer

The goal is to have the countdown timer to count down to a specific time in NYC (EST).
So the the timer goes to zero at 12:00 in NYC but in LA it would go to zero at 09:00
This is the code I use from W3Schools. But I don't have enough knowledge to add the timezone.
Can anyone help please :)
<script>
// Set the date we're counting down to
var countDownDate = new Date("Dec, 2019 12:00:00 GMT-0500").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 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 = hours + "h "
+ minutes + "m " + seconds + "s ";

Sorry, I did not read your answer carefully enough the 1st time.
Details here about padStart
a new language feature and an old work around (repeated below).
function pad(num, size) {
//num, string to be padded with leading zeros
//size, size of result after padding
//pads up to 10 characters
var s = "000000000" + num;
return s.substr(s.length-size);
}
var test='1';
console.log(pad('123456789',10)); //pads up to 10 char, result '0123456789'
console.log(pad(test,2)); //pads up to 2 char, result '01'

Display None on time

I have a Javascript code for a countdown timer. I want to use this code in a online shop order process. However I don't want to edit the date every day manually.
Now my question is: How can i display the div container from 6am to 2am (06.00 to 14.00).
From 14.00 to 06.00 i want that this container is display:none
// Set the date we're counting down to
var countDownDate = new Date("Jan 5, 2018 18:00:00").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("timer").innerHTML = "Bestellen Sie innerhalb der nächsten <span style='font-size:18px;color: #008a00!important;'>" + hours + " Stunden und "
+ minutes + " Minuten " + "</span>und wir versenden noch am gleichen Tag!";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("timer").innerHTML = "EXPIRED";
}
}, 1000);
var d = new Date();
if(d.getHours() >= 7 && d.getHours() <= 18 ){
$("#timer").show();
$(".closed").hide();
} else {
$(".closed").show();
$("#timer").hide();
}
<!-- Display the countdown timer in an element -->
<p id="timer"></p>
<p class="closed"></p>
Have anyone a solution for that?
