你可以在没有任何外部JS库的帮助下使用JS Date方法做到这一点，如下所示:

var date = new date (0); date.setSeconds (45);//指定SECONDS的值 var timeString = date.toISOString()。substring(11、19); console.log (timeString)

这是我最近为MM:SS写的。它不完全符合问题，但它是一种不同的单行格式。

const time = 60 * 2 + 35; // 2 minutes, 35 seconds
const str = (~~(time / 60) + "").padStart(2, '0') + ":" + (~~((time / 60) % 1 * 60) + "").padStart(2, '0');

str // 02:35

编辑:添加这个是为了多样化，但这里最好的解决方案是下面的https://stackoverflow.com/a/25279399/639679。

这是另一个版本，也处理天数:

function FormatSecondsAsDurationString( seconds )
{
    var s = "";

    var days = Math.floor( ( seconds / 3600 ) / 24 );
    if ( days >= 1 )
    {
        s += days.toString() + " day" + ( ( days == 1 ) ? "" : "s" ) + " + ";
        seconds -= days * 24 * 3600;
    }

    var hours = Math.floor( seconds / 3600 );
    s += GetPaddedIntString( hours.toString(), 2 ) + ":";
    seconds -= hours * 3600;

    var minutes = Math.floor( seconds / 60 );
    s += GetPaddedIntString( minutes.toString(), 2 ) + ":";
    seconds -= minutes * 60;

    s += GetPaddedIntString( Math.floor( seconds ).toString(), 2 );

    return s;
}

function GetPaddedIntString( n, numDigits )
{
    var nPadded = n;
    for ( ; nPadded.length < numDigits ; )
    {
        nPadded = "0" + nPadded;
    }

    return nPadded;
}

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。

最普遍的答案是

function hms(seconds) {
  return [3600, 60]
    .reduceRight(
      (p, b) => r => [Math.floor(r / b)].concat(p(r % b)),
      r => [r]
    )(seconds)
    .map(a => a.toString().padStart(2, '0'))
    .join(':');
}

一些示例输出:

> hms(0)
< "00:00:00"

> hms(5)
< "00:00:05"

> hms(60)
< "00:01:00"

> hms(3785)
< "01:03:05"

> hms(37850)
< "10:30:50"

> hms(378500)
< "105:08:20"

详见https://stackoverflow.com/a/66504936/1310733

const secondsToTime = (seconds, locale) => { const date = new date (0); 日期。setHours(0, 0, seconds, 0); 返回date.toLocaleTimeString(地区); ｝ “en”console.log (secondsToTime (3610));

在哪里区域参数(“en”，“de”等)是可选的
