我正在尝试计算设置的日期时间对象和当前时间之间经过的时间。我希望它能够以这种格式出现 DD:HH:MM:SS 其中 DD 是天，HH 是小时，MM 是分钟，SS 是秒。我能够得到总天数、总小时数、总分钟数和总秒数，但我不确定如何按照我想要的方式对其进行格式化。请帮忙<!DOCTYPE html><html><head> <meta charset="UTF-8"> <title>timer</title> </head><body ><div id ="time" name ="timer"></div><script>var myVar = setInterval(myTimer, 1000);function myTimer() { let seconds = 1000 ; let minutes = seconds * 60; let hours = minutes * 60; let days = hours * 24; let years = days * 365; const startDateTime = new Date("June 2, 2019 12:36:10 AM"); const newDateTime = new Date(); let timeDiff = newDateTime - startDateTime; let totalSeconds = Math.round(timeDiff/seconds); document.getElementById("time").innerHTML = totalSeconds;}</script></body></html>

我建议您使用像Moment.js这样的库，但是如果您想在纯 Javascript 中执行此操作，您可以将总秒数与您已经定义的除法参数相除，并在它们较少时用零填充它们十个以上。
var myVar = setInterval(myTimer, 1000);
const seconds = 1000;
const minutes = seconds * 60;
const hours = minutes * 60;
const days = hours * 24;
const years = days * 365;
function myTimer() {
const startDateTime = new Date("June 2, 2019 12:36:10 AM");
const newDateTime = new Date();
let elapsedMilliseconds = newDateTime - startDateTime;
document.getElementById("time").innerHTML =
`${formatElapsedTime(elapsedMilliseconds, days)}:${formatElapsedTime(elapsedMilliseconds, hours, 24)}:${formatElapsedTime(elapsedMilliseconds, minutes, 60)}:${formatElapsedTime(elapsedMilliseconds, seconds, 60)}`;
}
function formatElapsedTime(elapsedtime, timeunit, base) {
let time = base ? (elapsedtime / timeunit) % base : elapsedtime / timeunit;
time = Math.floor(time);
time = time < 10 ? '0' + time : time;
return time;
}
