你可以使用moment .js的moment-duration-format插件:

Var秒= 3820; Var duration =时刻。持续时间(秒,“秒”); Var format = duration.format("hh:mm:ss"); console.log(格式化);/ / 01:03:40 <！——Moment.js库——> .js库 < script src = " https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js " > < /脚本> <！——moment-duration-format插件——> < script src = " https://cdnjs.cloudflare.com/ajax/libs/moment-duration-format/1.3.0/moment-duration-format.min.js " > < /脚本>

我不喜欢在JavaScript中为标准数据类型添加属性，所以我建议这样做:

/**
 * Format a duration in seconds to a human readable format using the notion
 * "h+:mm:ss", e.g. "4:40:78". Negative durations are preceeded by "-".
 *
 * @param t Duration in seconds
 * @return The formatted duration string
 */
var readableDuration = (function() {

    // Each unit is an object with a suffix s and divisor d
    var units = [
        {s: '', d: 1}, // Seconds
        {s: ':', d: 60}, // Minutes
        {s: ':', d: 60}, // Hours
    ];

    // Closure function
    return function(t) {
        t = parseInt(t); // In order to use modulus
        var trunc, n = Math.abs(t), i, out = []; // out: list of strings to concat
        for (i = 0; i < units.length; i++) {
            n = Math.floor(n / units[i].d); // Total number of this unit
            // Truncate e.g. 26h to 2h using modulus with next unit divisor
            if (i+1 < units.length) // Tweak substr with two digits
                trunc = ('00'+ n % units[i+1].d).substr(-2, 2); // …if not final unit
            else
                trunc = n;
            out.unshift(''+ trunc + units[i].s); // Output
        }
        (t < 0) ? out.unshift('-') : null; // Handle negative durations
        return out.join('');
    };
})();

用法:

var str = readableDuration(3808); // "1:03:28"

我还创建了一个更通用的版本。主要的区别是它接受毫秒(这是JS中的标准时间单位)，而输出格式使用空格。

/**
 * 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}`
  }
}

s2t=function (t){
  return parseInt(t/86400)+'d '+(new Date(t%86400*1000)).toUTCString().replace(/.*(\d{2}):(\d{2}):(\d{2}).*/, "$1h $2m $3s");
}

s2t(123456);

结果:

1d 10h 17m 36s

主题的变奏。处理个位数秒的方式有点不同

seconds2time(0)  ->  "0s" 
seconds2time(59) -> "59s" 
seconds2time(60) -> "1:00" 
seconds2time(1000) -> "16:40" 
seconds2time(4000) -> "1:06:40"

function seconds2time (seconds) {
    var hours   = Math.floor(seconds / 3600);
    var minutes = Math.floor((seconds - (hours * 3600)) / 60);
    var seconds = seconds - (hours * 3600) - (minutes * 60);
    var time = "";

    if (hours != 0) {
      time = hours+":";
    }
    if (minutes != 0 || time !== "") {
      minutes = (minutes < 10 && time !== "") ? "0"+minutes : String(minutes);
      time += minutes+":";
    }
    if (time === "") {
      time = seconds+"s";
    }
    else {
      time += (seconds < 10) ? "0"+seconds : String(seconds);
    }
    return time;
}

可以使用以下函数将时间转换为HH:MM:SS格式:

var convertTime = function (input, separator) {
    var pad = function(input) {return input < 10 ? "0" + input : input;};
    return [
        pad(Math.floor(input / 3600)),
        pad(Math.floor(input % 3600 / 60)),
        pad(Math.floor(input % 60)),
    ].join(typeof separator !== 'undefined' ?  separator : ':' );
}

在不传递分隔符的情况下，它使用:作为(默认)分隔符:

time = convertTime(13551.9941351); // --> OUTPUT = 03:45:51

如果你想使用-作为分隔符，只需将其作为第二个参数传递:

time = convertTime(1126.5135155, '-'); // --> OUTPUT = 00-18-46

Demo

var convertTime = function (input, separator) { var pad = function(input) {return input < 10 ? "0" + input : input;}; return [ pad(Math.floor(input / 3600)), pad(Math.floor(input % 3600 / 60)), pad(Math.floor(input % 60)), ].join(typeof separator !== 'undefined' ? separator : ':' ); } document.body.innerHTML = '<pre>' + JSON.stringify({ 5.3515555 : convertTime(5.3515555), 126.2344452 : convertTime(126.2344452, '-'), 1156.1535548 : convertTime(1156.1535548, '.'), 9178.1351559 : convertTime(9178.1351559, ':'), 13555.3515135 : convertTime(13555.3515135, ',') }, null, '\t') + '</pre>';
