我有一个毫秒数的时间，我想将它转换为一种HH:MM:SS格式。它应该环绕，milliseconds = 86400000我想得到00:00:00.
如何在 JavaScript 中将时间以毫秒为单位转换为小时、分钟、秒格式？

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))将时间以毫秒为单位转换为人类可读的格式。
function msToTime(ms) {
let seconds = (ms / 1000).toFixed(1);
let minutes = (ms / (1000 * 60)).toFixed(1);
let hours = (ms / (1000 * 60 * 60)).toFixed(1);
let days = (ms / (1000 * 60 * 60 * 24)).toFixed(1);
if (seconds < 60) return seconds + " Sec";
else if (minutes < 60) return minutes + " Min";
else if (hours < 24) return hours + " Hrs";
else return days + " Days"
}
console.log(msToTime(1000))
console.log(msToTime(10000))
console.log(msToTime(300000))
console.log(msToTime(3600000))
console.log(msToTime(86400000))
我遇到了同样的问题，这就是我最终做的：
function parseMillisecondsIntoReadableTime(milliseconds){
//Get hours from milliseconds
var hours = milliseconds / (1000*60*60);
var absoluteHours = Math.floor(hours);
var h = absoluteHours > 9 ? absoluteHours : '0' + absoluteHours;
//Get remainder from hours and convert to minutes
var minutes = (hours - absoluteHours) * 60;
var absoluteMinutes = Math.floor(minutes);
var m = absoluteMinutes > 9 ? absoluteMinutes : '0' + absoluteMinutes;
//Get remainder from minutes and convert to seconds
var seconds = (minutes - absoluteMinutes) * 60;
var absoluteSeconds = Math.floor(seconds);
var s = absoluteSeconds > 9 ? absoluteSeconds : '0' + absoluteSeconds;
return h + ':' + m + ':' + s;
}
var time = parseMillisecondsIntoReadableTime(86400000);
alert(time);这是我的解决方案
let h,m,s;
h = Math.floor(timeInMiliseconds/1000/60/60);
m = Math.floor((timeInMiliseconds/1000/60/60 - h)*60);
s = Math.floor(((timeInMiliseconds/1000/60/60 - h)*60 - m)*60);
// 获取时间格式 00:00:00
s < 10 ? s = `0${s}`: s = `${s}`
m < 10 ? m = `0${m}`: m = `${m}`
h < 10 ? h = `0${h}`: h = `${h}`
console.log(`${s}:${m}:${h}`);
这个像youtube视频一样返回时间
function getYoutubeLikeToDisplay(millisec) {
var seconds = (millisec / 1000).toFixed(0);
var minutes = Math.floor(seconds / 60);
var hours = "";
if (minutes > 59) {
hours = Math.floor(minutes / 60);
hours = (hours >= 10) ? hours : "0" + hours;
minutes = minutes - (hours * 60);
minutes = (minutes >= 10) ? minutes : "0" + minutes;
}
seconds = Math.floor(seconds % 60);
seconds = (seconds >= 10) ? seconds : "0" + seconds;
if (hours != "") {
return hours + ":" + minutes + ":" + seconds;
}
return minutes + ":" + seconds;
}
输出：
- getYoutubeLikeToDisplay(129900) = "2:10"
- getYoutubeLikeToDisplay(1229900) = "20:30"
- getYoutubeLikeToDisplay(21229900) = "05:53:50"
