下面是一个函数，根据powtac的答案将秒转换为hh-mm-ss格式

斯菲德尔

/** 
 * Convert seconds to hh-mm-ss format.
 * @param {number} totalSeconds - the total seconds to convert to hh- mm-ss
**/
var SecondsTohhmmss = function(totalSeconds) {
  var hours   = Math.floor(totalSeconds / 3600);
  var minutes = Math.floor((totalSeconds - (hours * 3600)) / 60);
  var seconds = totalSeconds - (hours * 3600) - (minutes * 60);

  // round seconds
  seconds = Math.round(seconds * 100) / 100

  var result = (hours < 10 ? "0" + hours : hours);
      result += "-" + (minutes < 10 ? "0" + minutes : minutes);
      result += "-" + (seconds  < 10 ? "0" + seconds : seconds);
  return result;
}

示例使用

var seconds = SecondsTohhmmss(70);
console.log(seconds);
// logs 00-01-10

下面是将秒转换为hh-mm-ss格式的代码:

var measuredTime = new Date(null);
measuredTime.setSeconds(4995); // specify value of SECONDS
var MHSTime = measuredTime.toISOString().substr(11, 8);

在JavaScript中获得从将秒转换为HH-MM-SS格式的替代方法

正如Cleiton在他的回答中指出的，moment.js可以用于:

moment().startOf('day')
        .seconds(15457)
        .format('H:mm:ss');

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);

试试这个:

function toTimeString(seconds) {
  return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}

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(':');
};
