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), );

说说我的意见:
function convertSecondsToMinutesAndSeconds(seconds){
var minutes;
var seconds;
minutes = Math.floor(seconds/60);
seconds = seconds%60;
return [minutes, seconds];
}
所以这个:
var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);
将有以下输出:
[1,41];
然后你可以像这样打印它:
console.log('TIME : ' + minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');
//TIME : 1 minutes, 41 seconds
使用ES6清洁一个衬垫
const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);
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;)
试试这个: 将秒转换为小时，分钟和秒。
function convertTime(sec) {
var hours = Math.floor(sec/3600);
(hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
var min = Math.floor(sec/60);
(min >= 1) ? sec = sec - (min*60) : min = '00';
(sec < 1) ? sec='00' : void 0;
(min.toString().length == 1) ? min = '0'+min : void 0;
(sec.toString().length == 1) ? sec = '0'+sec : void 0;
return hours+':'+min+':'+sec;
}
