js / timestamp问题的倒计时

// 获取当前时间的时间戳
var currentTime = Date.now();

// 获取目标结束时间的时间戳（假设为一小时后）
var targetTime = new Date();
targetTime.setHours(targetTime.getHours() + 1);
var targetTimestamp = targetTime.getTime();

// 计算剩余时间
var remainingTime = targetTimestamp - currentTime;

// 将剩余时间转换为天、小时、分钟和秒
var days = Math.floor(remainingTime / (1000 * 60 * 60 * 24));
var hours = Math.floor((remainingTime % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((remainingTime % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((remainingTime % (1000 * 60)) / 1000);

// 更新倒计时显示的界面元素
document.getElementById("days").innerHTML = days;
document.getElementById("hours").innerHTML = hours;
document.getElementById("minutes").innerHTML = minutes;
document.getElementById("seconds").innerHTML = seconds;
