如何在JavaScript中将以毫秒为单位的时间转换为小时，分钟，秒的格式? [英] How to convert time in milliseconds to hours, min, sec format in JavaScript?

问题描述

我的时间以毫秒为单位，我想将其转换为 HH:MM:SS 格式.它应该环绕起来，毫秒= 86400000 ，我想得到 00:00:00 .

I have a time as a number of milliseconds and I want to convert it to a HH:MM:SS format. It should wrap around, with milliseconds = 86400000 I want to get 00:00:00.

推荐答案

如何创建这样的函数:

function msToTime(duration) {
  var milliseconds = Math.floor((duration % 1000) / 100),
    seconds = Math.floor((duration / 1000) % 60),
    minutes = Math.floor((duration / (1000 * 60)) % 60),
    hours = Math.floor((duration / (1000 * 60 * 60)) % 24);

  hours = (hours < 10) ? "0" + hours : hours;
  minutes = (minutes < 10) ? "0" + minutes : minutes;
  seconds = (seconds < 10) ? "0" + seconds : seconds;

  return hours + ":" + minutes + ":" + seconds + "." + milliseconds;
}
console.log(msToTime(300000))
