I recently developed a countdown timer using JavaScript and included an event listener for a stop button to pause the timer
When I stopped the timer, every second was being logged individually but I wanted to only retrieve the final time value. For example, if the start time was 59:00 minutes and the stop time was 50:15 minutes, I only wanted to display the stop time of 50:15 minutes.
Please see the code snippet below:
function getTimeRemaining(endtime) {
const total = Date.parse(endtime) - Date.parse(new Date());
const seconds = Math.floor((total / 1000) % 60);
const minutes = Math.floor((total / 1000 / 60) % 60);
const hours = Math.floor((total / (1000 * 60 * 60)) % 24);
const days = Math.floor(total / (1000 * 60 * 60 * 24));
return {
total,
days,
hours,
minutes,
seconds
};
}
function initializeClock(id, endtime) {
const clock = document.getElementById(id);
const daysSpan = clock.querySelector('.days');
const hoursSpan = clock.querySelector('.hours');
const minutesSpan = clock.querySelector('.minutes');
const secondsSpan = clock.querySelector('.seconds');
/* buttons */
const startbutton = document.getElementById('Startbtn')
const stopbtton = document.getElementById('Stopbtn');
function updateClock() {
const 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);
} else {
stopbtton.addEventListener('click', (e) => {
clearInterval(timeinterval);
var StopTime = t.minutes + ":" + t.seconds;
console.log(StopTime); // returned as a single item
})
}
}
// updateClock();
const timeinterval = setInterval(updateClock, 1000);
}
const deadline = new Date(Date.parse(new Date()) + 15 * 24 * 60 * 60 * 1000);
initializeClock('clockdiv', deadline);
How can I ensure that only the last stop time value is displayed instead of each individual second?
Your help is greatly appreciated!
