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?

另一种更优雅的解决方案如下:
/**
* Convert number secs to display time
*
* 65 input becomes 01:05.
*
* @param Number inputSeconds Seconds input.
*/
export const toMMSS = inputSeconds => {
const secs = parseInt( inputSeconds, 10 );
let minutes = Math.floor( secs / 60 );
let seconds = secs - minutes * 60;
if ( 10 > minutes ) {
minutes = '0' + minutes;
}
if ( 10 > seconds ) {
seconds = '0' + seconds;
}
// Return display.
return minutes + ':' + seconds;
};

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(':') ｝
我在想一个更快的方法来完成这件事，这就是我想到的
var sec = parseInt(time);
var min=0;
while(sec>59){ sec-=60; min++;}
如果我们想要将“时间”转换为分钟和秒，例如:
// time = 75,3 sec
var sec = parseInt(time); //sec = 75
var min=0;
while(sec>59){ sec-=60; min++;} //sec = 15; min = 1
要添加前导零，我只需这样做:
const secondstom昆虫填充=时间=> { const minutes = "0" + Math。楼层(时间/ 60); Const seconds = "0" +(时间-分钟* 60); 返回minutes.substr(-2) + ":" + seconds.substr(-2); }; console.log (secondsToMinSecPadded (241));
很好，很短
下面的函数将帮助您获得日，小时，分钟，秒
toDDHHMMSS(inputSeconds){
const Days = Math.floor( inputSeconds / (60 * 60 * 24) );
const Hour = Math.floor((inputSeconds % (60 * 60 * 24)) / (60 * 60));
const Minutes = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) / 60 );
const Seconds = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) % 60 );
let ddhhmmss = '';
if (Days > 0){
ddhhmmss += Days + ' Day ';
}
if (Hour > 0){
ddhhmmss += Hour + ' Hour ';
}
if (Minutes > 0){
ddhhmmss += Minutes + ' Minutes ';
}
if (Seconds > 0){
ddhhmmss += Seconds + ' Seconds ';
}
return ddhhmmss;
}
alert( toDDHHMMSS(2000));
