我喜欢Powtac的答案，但我想在angular.js中使用它，所以我用他的代码创建了一个过滤器。

.filter('HHMMSS', ['$filter', function ($filter) {
    return function (input, decimals) {
        var sec_num = parseInt(input, 10),
            decimal = parseFloat(input) - sec_num,
            hours   = Math.floor(sec_num / 3600),
            minutes = Math.floor((sec_num - (hours * 3600)) / 60),
            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;
        if (decimals > 0) {
            time += '.' + $filter('number')(decimal, decimals).substr(2);
        }
        return time;
    };
}])

它在功能上是相同的，除了我添加了一个可选的小数字段来显示小数秒。像使用其他过滤器一样使用它:

{{elapsedTime | HHMMSS}}显示:01:23:45

{{elapsedTime | HHMMSS: 3}}显示:01:23:45.678

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。

我看到每个人都在发布他们对这个问题的看法，尽管事实上很少有顶级答案已经包含了针对特定用例定制的所有必要信息。

既然我也想赶时髦——下面是我不必要的、有点麻烦的解决方案，那就是:

a)可读性强(希望如此!) b)易于定制 c)不打印任何零

滚筒滚

function durationToDDHHMMSSMS(durms) {
    if (!durms) return "??";

    var HHMMSSMS = new Date(durms).toISOString().substr(11, 12);
    if (!HHMMSSMS) return "??";

    var HHMMSS = HHMMSSMS.split(".")[0];
    if (!HHMMSS) return "??";

    var MS = parseInt(HHMMSSMS.split(".")[1],10);
    var split = HHMMSS.split(":");
    var SS = parseInt(split[2],10);
    var MM = parseInt(split[1],10);
    var HH = parseInt(split[0],10); 
    var DD = Math.floor(durms/(1000*60*60*24));

    var string = "";
    if (DD) string += ` ${DD}d`;
    if (HH) string += ` ${HH}h`;
    if (MM) string += ` ${MM}m`;
    if (SS) string += ` ${SS}s`;
    if (MS) string += ` ${MS}ms`;

    return string;
},

注意，这段代码使用ES6模板字符串，我相信像你这样聪明的人在需要时用常规字符串替换它们没有困难。

secToHHMM(number: number) {
    debugger;
    let hours = Math.floor(number / 3600);
    let minutes = Math.floor((number - (hours * 3600)) / 60);
    let seconds = number - (hours * 3600) - (minutes * 60);
    let H, M, S;
    if (hours < 10) H = ("0" + hours);
    if (minutes < 10) M = ("0" + minutes);
    if (seconds < 10) S = ("0" + seconds);
    return (H || hours) + ':' + (M || minutes) + ':' + (S || seconds);
}

我认为这是目前为止最快的性能:

var t = 34236; // your seconds
var time = ('0'+Math.floor(t/3600) % 24).slice(-2)+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2)
//would output: 09:30:36

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');
