这是一个常见的问题，但我不知道如何解决它。下面的代码可以正常工作。
var mind = time % (60 * 60);
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
然而，当我到达1小时或3600秒时，它返回0分和0秒。我如何避免这种情况，让它返回所有的分钟?

在这一切之后，还有一个简单的解决方案:
const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());

另一个奇妙的解决方案:
function fancyTimeFormat(duration) { // Hours, minutes and seconds const hrs = ~~(duration / 3600); const mins = ~~((duration % 3600) / 60); const secs = ~~duration % 60; // Output like "1:01" or "4:03:59" or "123:03:59" let ret = ""; if (hrs > 0) { ret += "" + hrs + ":" + (mins < 10 ? "0" : ""); } ret += "" + mins + ":" + (secs < 10 ? "0" : ""); ret += "" + secs; return ret; } console.log( fancyTimeFormat(1), fancyTimeFormat(10), fancyTimeFormat(100), fancyTimeFormat(1000), fancyTimeFormat(10000), );
~~是Math的缩写。楼层，请参阅此链接以获取更多信息
export function TrainingTime(props) {
const {train_time } = props;
const hours = Math.floor(train_time/3600);
const minutes = Math.floor((train_time-hours * 3600) / 60);
const seconds = Math.floor((train_time%60));
return `${hours} hrs ${minutes} min ${seconds} sec`;
}
您已经编写了足够多的代码来跟踪时间的分钟和秒部分。
你可以把时间因素加进去:
var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);
var mind = hrd % 60;
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
var moreminutes = minutes + hours * 60
你也可以使用本机Date对象:
var date = new Date(null);
date.setSeconds(timeInSeconds);
// retrieve time ignoring the browser timezone - returns hh:mm:ss
var utc = date.toUTCString();
// negative start index in substr does not work in IE 8 and earlier
var time = utc.substr(utc.indexOf(':') - 2, 8)
// retrieve each value individually - returns h:m:s
var time = date.getUTCHours() + ':' + date.getUTCMinutes() + ':' + date.getUTCSeconds();
// does not work in IE8 and below - returns hh:mm:ss
var time = date.toISOString().substr(11, 8);
// not recommended - only if seconds number includes timezone difference
var time = date.toTimeString().substr(0, 8);
当然，这个解决方案只适用于小于24小时的timeInSeconds;)

格式hh: mm: ss
Console.log (display(60 * 60 * 2.5 + 25)) // 2.5小时+ 25秒 功能显示(秒){ const format = val => ' 0${Math.floor(val)} ' .slice(-2) Const hours = seconds / 3600 Const minutes = (seconds % 3600) / 60 返回[hours, minutes, seconds % 60].map(format).join(':') ｝
