易于遵循的版本为菜鸟:

 var totalNumberOfSeconds = YOURNUMBEROFSECONDS;
 var hours = parseInt( totalNumberOfSeconds / 3600 );
 var minutes = parseInt( (totalNumberOfSeconds - (hours * 3600)) / 60 );
 var seconds = Math.floor((totalNumberOfSeconds - ((hours * 3600) + (minutes * 60))));
 var result = (hours < 10 ? "0" + hours : hours) + ":" + (minutes < 10 ? "0" + minutes : minutes) + ":" + (seconds  < 10 ? "0" + seconds : seconds);
 console.log(result);

Here is an extension to Number class. toHHMMSS() converts seconds to an hh:mm:ss string. Number.prototype.toHHMMSS = function() { var hours = Math.floor(this / 3600) < 10 ? ("00" + Math.floor(this / 3600)).slice(-2) : Math.floor(this / 3600); var minutes = ("00" + Math.floor((this % 3600) / 60)).slice(-2); var seconds = ("00" + (this % 3600) % 60).slice(-2); return hours + ":" + minutes + ":" + seconds; } // Usage: [number variable].toHHMMSS(); // Here is a simple test var totalseconds = 1234; document.getElementById("timespan").innerHTML = totalseconds.toHHMMSS(); // HTML of the test <div id="timespan"></div>

你也可以用Sugar。

Date.create().reset().set({seconds: 180}).format('{mm}:{ss}');

这个例子返回'03:00'。

export const secondsToHHMMSS = (seconds) => {
  const HH = `${Math.floor(seconds / 3600)}`.padStart(2, '0');
  const MM = `${Math.floor(seconds / 60) % 60}`.padStart(2, '0');
  const SS = `${Math.floor(seconds % 60)}`.padStart(2, '0');
  return [HH, MM, SS].join(':');
};

这是一个非常简单的任务，但你们中的一些人直接推荐了Moment.js，或者创建了一些最丑陋的函数来解析一些秒…

transform(time: number): string {
    if (time != null) {
        const hours: number = Math.floor(time / 3600);
        const minutes: number = Math.floor((time - (hours * 3600)) / 60);
        const seconds: number = time - (hours * 3600) - (minutes * 60);
        return [hours, (minutes < 10) ? '0' + minutes : minutes, (seconds < 10) ? '0' + seconds : seconds].join(':');
    } else {
        return '00:00:00';
    }
}

这在任何情况下都适用……

在一行中，使用T.J.克劳德的解决方案:

secToHHMMSS = seconds => `${Math.floor(seconds / 3600)}:${Math.floor((seconds % 3600) / 60)}:${Math.floor((seconds % 3600) % 60)}`

在一行中，另一个计算天数的解决方案:

secToDHHMMSS = seconds => `${parseInt(seconds / 86400)}d ${new Date(seconds * 1000).toISOString().substr(11, 8)}`
