Important factors to remember:
This is programmed to imitate the time of 11:00 PM.
var bt = "23:00";
This is set to emulate 8:00 AM.
var wt = "08:00";
The intended operation:
- The countdown timer kicks off each morning at 8:00 AM.
- It counts down until 11:00 PM, every night.
- At that point, it displays 00:00:00.
- When morning comes, at 8:00 AM, the countdown restarts once more.
- This cycle should continue indefinitely.
The current issue:
- Everything seems functional, except it starts a 24-hour countdown at midnight up until 8:00 AM.
I have attempted to troubleshoot this problem, and my suspicion is that the error lies in how the distance variable is calculated, causing the code to anticipate the next day, but I am unsure how to rectify this.
Here is the link to the Codepen.
and here is the excerpt from my JS script:
$(document).ready(function () {
var bt = "23:00"; // 11:00 PM
var wt = "08:00"; // 08:00 AM
var dateNow = moment().format('MMM D, YYYY');
placeHolderDate = dateNow + " " + bt;
var timeNow = moment().format('HH:mm');
var countDownDate = new Date(placeHolderDate).getTime();
var countDownHourMin = (wt.split(":"));
// 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 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);
$("#countDown").val(hours + ":" + minutes + ":" + seconds);
// If the countdown is over, write some text
if (hours === 0 && minutes === 0 && seconds === 0) {
//clearInterval(x);
$("#countDown").val("00:00:00");
}
if (hours < 0 || minutes < 0 || seconds < 0) {
//clearInterval(x);
$("#countDown").val("00:00:00");
}
var timeNow = moment().format('HH:mm');
//console.log('Time Now:' + timeNow);
//console.log('Wake Time:' + wt);
if (timeNow === wt) {
clearInterval(x);
restartCountdown();
}
//console.log(hours + ":" + minutes + ":" + seconds);
}, 1000);
function restartCountdown() {
//log("restartCountdown Started!");
var bt = "23:00"; // 11:00 PM
var wt = "08:00"; // 08:00 AM
var dN = (moment().add(moment.duration({d: 1})).format('MMM D, YYYY'));
console.log('dn ' + dN);
var placeHolderDate = dN + " " + bt;
var countDownDate = new Date(placeHolderDate).getTime();
var countDownHourMin = (wt.split(":"));
// 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 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);
$("#countDown").val(hours + ":" + minutes + ":" + seconds);
// If the countdown is over, write some text
if (hours === 0 && minutes === 0 && seconds === 0) {
//clearInterval(x);
$("#countDown").val("00:00:00");
}
if (hours < 0 || minutes < 0 || seconds < 0) {
//clearInterval(x);
$("#countDown").val("00:00:00");
}
// console.log(hours + ":" + minutes + ":" + seconds);
}, 1000);
}
});
