How do I restart countdown timer to 120 seconds every time a new user lands on the page?
问题
<style>#countdown {font-size: 36px;font-weight: bold;color: white;text-align: center;margin: 20px 0;}</style><p id="countdown"></p><script>function updateCountdown() {let startTime = new Date("2023-02-28T15:22:00");const currentTime = new Date();let diffTime = startTime - currentTime;let totalSeconds = diffTime / 1000;while (totalSeconds <= 0) {startTime.setDate(startTime.getDate() + 7);diffTime = startTime - currentTime;totalSeconds = diffTime / 1000;}const days = Math.floor(totalSeconds / (24 * 60 * 60));const hours = Math.floor((totalSeconds % (24 * 60 * 60)) / (60 * 60));const minutes = Math.floor((totalSeconds % (60 * 60)) / 60);const seconds = Math.floor(totalSeconds % 60);document.getElementById("countdown").innerHTML = `${days}d ${hours}h ${minutes}m ${seconds}s`;}setInterval(updateCountdown, 1000);</script>

I am trying to use this snippet to refresh a countdown timer to 120 seconds when a new user lands on the page. Any help is appreciated.
I am having trouble on two things: how to set the start date to the current time and then to have this countdown from 120 seconds vs. 7 days.
<style>#countdown {font-size: 36px;font-weight: bold;color: white;text-align: center;margin: 20px 0;}</style><p id="countdown"></p><script>function updateCountdown() {let startTime = new Date("2023-02-28T15:22:00");const currentTime = new Date();let diffTime = startTime - currentTime;let totalSeconds = diffTime / 1000;while (totalSeconds <= 0) {startTime.setDate(startTime.getDate() + 7);diffTime = startTime - currentTime;totalSeconds = diffTime / 1000;}const days = Math.floor(totalSeconds / (24 * 60 * 60));const hours = Math.floor((totalSeconds % (24 * 60 * 60)) / (60 * 60));const minutes = Math.floor((totalSeconds % (60 * 60)) / 60);const seconds = Math.floor(totalSeconds % 60);document.getElementById("countdown").innerHTML = `${days}d ${hours}h ${minutes}m ${seconds}s`;}setInterval(updateCountdown, 1000);</script>

你可以使用
document.addEventListener('DOMContentLoaded', function() {
// 重置计时器
});
像这样
英文:
You can use
document.addEventListener('DOMContentLoaded', function() {// reset timer});
like this
