我的时间以毫秒为单位,但是我希望转换后的时间像00:00:00
。
例如:以毫秒为单位= 86400000。我想要几毫秒之内的时间,00:00:00
如何在JavaScript中获得它?
Answers:
如何通过在javascript中创建函数来做到这一点,如下所示:
function msToTime(duration) {
var milliseconds = parseInt((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))
将毫秒转换为人类可读的格式。
function timeConversion(millisec) {
var seconds = (millisec / 1000).toFixed(1);
var minutes = (millisec / (1000 * 60)).toFixed(1);
var hours = (millisec / (1000 * 60 * 60)).toFixed(1);
var days = (millisec / (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"
}
}
我遇到了同样的问题,这就是我最终要做的事情:
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:
-3000
应该显示-00:03
但返回-1:0-03
。
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}:${h}`);
s = `${s < 10 ? '0': ''}${s}`
不好意思,晚到晚会。接受的答案对我而言并没有切合实际,所以我自己写了它。
输出:
2h 59s
1h 59m
1h
1h 59s
59m 59s
59s
代码(打字稿):
function timeConversion(duration: number) {
const portions: string[] = [];
const msInHour = 1000 * 60 * 60;
const hours = Math.trunc(duration / msInHour);
if (hours > 0) {
portions.push(hours + 'h');
duration = duration - (hours * msInHour);
}
const msInMinute = 1000 * 60;
const minutes = Math.trunc(duration / msInMinute);
if (minutes > 0) {
portions.push(minutes + 'm');
duration = duration - (minutes * msInMinute);
}
const seconds = Math.trunc(duration / 1000);
if (seconds > 0) {
portions.push(seconds + 's');
}
return portions.join(' ');
}
console.log(timeConversion((60 * 60 * 1000) + (59 * 60 * 1000) + (59 * 1000)));
console.log(timeConversion((60 * 60 * 1000) + (59 * 60 * 1000) ));
console.log(timeConversion((60 * 60 * 1000) ));
console.log(timeConversion((60 * 60 * 1000) + (59 * 1000)));
console.log(timeConversion( (59 * 60 * 1000) + (59 * 1000)));
console.log(timeConversion( (59 * 1000)));
以上代码段不适用于超过1天的案例(它们将被忽略)。
为此,您可以使用:
function convertMS(ms) {
var d, h, m, s;
s = Math.floor(ms / 1000);
m = Math.floor(s / 60);
s = s % 60;
h = Math.floor(m / 60);
m = m % 60;
d = Math.floor(h / 24);
h = h % 24;
h += d * 24;
return h + ':' + m + ':' + s;
}
return (h < 10 ? "0" + h : h) + ":" + (m < 10 ? "0" + m : m) + ":" + (s < 10 ? "0" + s : s);
,因为用数学比一堆字符串操作更好。
基于@Chand的答案。这是Typescript中的实现。比强制使用JS中的类型更安全。如果删除类型注释,则应为有效的JS。还使用新的字符串函数将时间标准化。
function displayTime(millisec: number) {
const normalizeTime = (time: string): string => (time.length === 1) ? time.padStart(2, '0') : time;
let seconds: string = (millisec / 1000).toFixed(0);
let minutes: string = Math.floor(parseInt(seconds) / 60).toString();
let hours: string = '';
if (parseInt(minutes) > 59) {
hours = normalizeTime(Math.floor(parseInt(minutes) / 60).toString());
minutes = normalizeTime((parseInt(minutes) - (parseInt(hours) * 60)).toString());
}
seconds = normalizeTime(Math.floor(parseInt(seconds) % 60).toString());
if (hours !== '') {
return `${hours}:${minutes}:${seconds}`;
}
return `${minutes}:${seconds}`;
}
我最多只需要一天24小时的时间,这就是我的看法:
const milliseconds = 5680000;
const hours = `0${new Date(milliseconds).getHours() - 1}`.slice(-2);
const minutes = `0${new Date(milliseconds).getMinutes()}`.slice(-2);
const seconds = `0${new Date(milliseconds).getSeconds()}`.slice(-2);
const time = `${hours}:${minutes}:${seconds}`
console.log(time);
如果需要,您也可以通过这种方式获得几天的服务。
此解决方案使用一个function
将毫秒分割为parts object
,然后使用另一个function
格式化parts object
。
我创建了2种格式函数,一种按您的要求,另一种打印友好的字符串并考虑单数/复数,并包括一个显示毫秒的选项。
function parseDuration(duration) {
let remain = duration
let days = Math.floor(remain / (1000 * 60 * 60 * 24))
remain = remain % (1000 * 60 * 60 * 24)
let hours = Math.floor(remain / (1000 * 60 * 60))
remain = remain % (1000 * 60 * 60)
let minutes = Math.floor(remain / (1000 * 60))
remain = remain % (1000 * 60)
let seconds = Math.floor(remain / (1000))
remain = remain % (1000)
let milliseconds = remain
return {
days,
hours,
minutes,
seconds,
milliseconds
};
}
function formatTime(o, useMilli = false) {
let parts = []
if (o.days) {
let ret = o.days + ' day'
if (o.days !== 1) {
ret += 's'
}
parts.push(ret)
}
if (o.hours) {
let ret = o.hours + ' hour'
if (o.hours !== 1) {
ret += 's'
}
parts.push(ret)
}
if (o.minutes) {
let ret = o.minutes + ' minute'
if (o.minutes !== 1) {
ret += 's'
}
parts.push(ret)
}
if (o.seconds) {
let ret = o.seconds + ' second'
if (o.seconds !== 1) {
ret += 's'
}
parts.push(ret)
}
if (useMilli && o.milliseconds) {
let ret = o.milliseconds + ' millisecond'
if (o.milliseconds !== 1) {
ret += 's'
}
parts.push(ret)
}
if (parts.length === 0) {
return 'instantly'
} else {
return parts.join(' ')
}
}
function formatTimeHMS(o) {
let hours = o.hours.toString()
if (hours.length === 1) hours = '0' + hours
let minutes = o.minutes.toString()
if (minutes.length === 1) minutes = '0' + minutes
let seconds = o.seconds.toString()
if (seconds.length === 1) seconds = '0' + seconds
return hours + ":" + minutes + ":" + seconds
}
function formatDurationHMS(duration) {
let time = parseDuration(duration)
return formatTimeHMS(time)
}
function formatDuration(duration, useMilli = false) {
let time = parseDuration(duration)
return formatTime(time, useMilli)
}
console.log(formatDurationHMS(57742343234))
console.log(formatDuration(57742343234))
console.log(formatDuration(5423401000))
console.log(formatDuration(500))
console.log(formatDuration(500, true))
console.log(formatDuration(1000 * 30))
console.log(formatDuration(1000 * 60 * 30))
console.log(formatDuration(1000 * 60 * 60 * 12))
console.log(formatDuration(1000 * 60 * 60 * 1))
为我工作
msToTime(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 == "00" ? m + ':' + s : h + ':' + m + ':' + s;
}
用于人类可读输出的人类可读代码,您可以将其扩展到十亿分之一秒或十亿分之一秒或非常直观的内容。显然,您希望将其转换为函数,然后重新使用其中一些中间模调用。
second = 1000
minute = second * 60
hour = minute * 60
day = hour * 24
test = 3 * day + 2 * hour + 11 * minute + 58 * second
console.log(Math.floor(test / day))
console.log(Math.floor(test % day / hour))
console.log(Math.floor(test % day % hour / minute))
console.log(Math.floor(test % day % hour % minute / second))
我的解决方案
var sunriseMills = 1517573074000; // sunrise in NewYork on Feb 3, 2018 - UTC time
var offsetCityMills = -5 * 3600 * 1000; // NewYork delay to UTC
var offsetDeviceMills = new Date().getTimezoneOffset() * 60 * 1000 ; // eg. I live in Romania (UTC+2) >> getTimezoneOffset() = 120
var textTime = new Date(sunriseMills + offsetCityMills + offsetDeviceMills)
.toLocaleTimeString('en-US', { hour: 'numeric', minute: 'numeric' });
textTime将变为' 7.04 AM '
我为我工作,因为我使用javascript方法getTime()来获取毫秒= 1592380675409,该方法返回1970年1月1日午夜到指定日期之间的毫秒数。
var d = new Date();//Wed Jun 17 2020 13:27:55 GMT+0530 (India Standard Time)
var n = d.getTime();//1592380675409 this value is store somewhere
//function call
console.log(convertMillisecToHrMinSec(1592380675409));
var convertMillisecToHrMinSec = (time) => {
let date = new Date(time);
let hr = date.getHours();
let min = date.getMinutes();
let sec = date.getSeconds();
hr = (hr < 10) ? "0"+ hr : hr;
min = (min < 10) ? "0"+ min : min;
sec = (sec < 10) ? "0"+ sec : sec;
return hr + ':' + min + ":" + sec;//01:27:55
}
如果您使用打字稿,这对您可能是一件好事
enum ETime {
Seconds = 1000,
Minutes = 60000,
Hours = 3600000,
SecInMin = 60,
MinInHours = 60,
HoursMod = 24,
timeMin = 10,
}
interface ITime {
millis: number
modulo: number
}
const Times = {
seconds: {
millis: ETime.Seconds,
modulo: ETime.SecInMin,
},
minutes: {
millis: ETime.Minutes,
modulo: ETime.MinInHours,
},
hours: {
millis: ETime.Hours,
modulo: ETime.HoursMod,
},
}
const dots: string = ":"
const msToTime = (duration: number, needHours: boolean = true): string => {
const getCorrectTime = (divider: ITime): string => {
const timeStr: number = Math.floor(
(duration / divider.millis) % divider.modulo,
)
return timeStr < ETime.timeMin ? "0" + timeStr : String(timeStr)
}
return (
(needHours ? getCorrectTime(Times.hours) + dots : "") +
getCorrectTime(Times.minutes) +
dots +
getCorrectTime(Times.seconds)
)
}
在我的实现中,我使用了Moment.js:
export default (value) =>
const duration = moment.duration(value);
const milliseconds = duration.milliseconds();
const seconds = duration.seconds();
const minutes = duration.minutes();
const hours = duration.hours();
const day = duration.days();
const sDay = `${day}d `;
const sHours = (hours < 10) ? `0${hours}h ` : `${hours}h `;
const sMinutes = (minutes < 10) ? `0${minutes}' ` : `${minutes}' `;
const sSeconds = (seconds < 10) ? `0${seconds}" ` : `${seconds}" `;
const sMilliseconds = `${milliseconds}ms`;
...
}
一旦得到了琴弦,我就可以根据自己的需要创作它们了。
