以下是我的看法:

function formatTime(seconds) {
  const h = Math.floor(seconds / 3600);
  const m = Math.floor((seconds % 3600) / 60);
  const s = Math.round(seconds % 60);
  return [
    h,
    m > 9 ? m : (h ? '0' + m : m || '0'),
    s > 9 ? s : '0' + s
  ].filter(Boolean).join(':');
}

预期结果:

const expect = require('expect');
expect(formatTime(0)).toEqual('0:00');
expect(formatTime(1)).toEqual('0:01');
expect(formatTime(599)).toEqual('9:59');
expect(formatTime(600)).toEqual('10:00');
expect(formatTime(3600)).toEqual('1:00:00');
expect(formatTime(360009)).toEqual('100:00:09');
expect(formatTime(0.2)).toEqual('0:00');

下面是一个使用Date.prototype.toLocaleTimeString()的例子。我选择GB作为语言，因为美国在最初的小时显示的是24而不是00。此外，我选择Etc/UTC作为时区，因为UTC在tz数据库时区列表中是它的别名。

const formatTime = (seconds) => 新日期(秒* 1000)。toLocaleTimeString(“en”{ 时区:“等/ UTC ', hour12:假的, 小时:“便是”, 分钟:“便是”, 第二:“便是” })； console.log (formatTime (75));/ / 00:01:15 .as-console-wrapper {top: 0;Max-height: 100%重要;｝

下面是相同的示例，但是使用了Intl.DateTimeFormat。这个变体允许您实例化一个可重用的格式化器对象，这更具有性能。

const dateFormatter = new Intl。DateTimeFormat(“en”{ 时区:“等/ UTC ', hour12:假的, 小时:“便是”, 分钟:“便是”, 第二:“便是” })； const formatTime = (seconds) => dateFormatter。format(new Date(seconds * 1000)); console.log (formatTime (75));/ / 00:01:15 .as-console-wrapper {top: 0;Max-height: 100%重要;｝

/**
 * Formats seconds (number) to H:i:s format.
 * 00:12:00
 *
 * When "short" option is set to true, will return:
 * 0:50
 * 2:00
 * 12:00
 * 1:00:24
 * 10:00:00
 */
export default function formatTimeHIS (seconds, { short = false } = {}) {
  const pad = num => num < 10 ? `0${num}` : num

  const H = pad(Math.floor(seconds / 3600))
  const i = pad(Math.floor(seconds % 3600 / 60))
  const s = pad(seconds % 60)

  if (short) {
    let result = ''
    if (H > 0) result += `${+H}:`
    result += `${H > 0 ? i : +i}:${s}`
    return result
  } else {
    return `${H}:${i}:${s}`
  }
}

下面是它的es6版本:

export const parseTime = (time) => { // send time in seconds
// eslint-disable-next-line 
let hours = parseInt(time / 60 / 60), mins = Math.abs(parseInt(time / 60) - (hours * 60)), seconds = Math.round(time % 60);
return isNaN(hours) || isNaN(mins) || isNaN(seconds) ? `00:00:00` : `${hours > 9 ? Math.max(hours, 0) : '0' + Math.max(hours, 0)}:${mins > 9 ? Math.max(mins, 0) : '0' + Math.max(0, mins)}:${seconds > 9 ? Math.max(0, seconds) : '0' + Math.max(0, seconds)}`;}

toHHMMSS的非原型版本:

    function toHHMMSS(seconds) {
        var sec_num = parseInt(seconds);
        var hours   = Math.floor(sec_num / 3600);
        var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
        var seconds = sec_num - (hours * 3600) - (minutes * 60);        
        if (hours   < 10) {hours   = "0"+hours;}
        if (minutes < 10) {minutes = "0"+minutes;}
        if (seconds < 10) {seconds = "0"+seconds;}
        var time    = hours+':'+minutes+':'+seconds;
        return time;
    }   

以下是我的解决方案。您可以尝试下面的代码片段。

函数secToHHMM(sec) { var d = new Date(); d.setHours (0); d.setMinutes (0); d.setSeconds (0); d = new Date(d.getTime() + sec*1000); 返回d.toLocaleString (en)。分割(' ')[1]; }; alert('One hour: ' + secToHHMM(60*60));/ /“01:00:00” alert(' 1小时5分钟:' + secToHHMM(60*60 + 5*60));/ /“01:05:00” alert(' 1小时5分23秒:' + secToHHMM(60*60 + 5*60 + 23));/ /“01:05:23”
