以下是对Sky Sander的解决方案的轻微修改，允许日期作为字符串输入，并能够显示像“1分钟”而不是“73秒”这样的跨度

var timeSince = function(date) { if (typeof date !== 'object') { date = new Date(date); } var seconds = Math.floor((new Date() - date) / 1000); var intervalType; var interval = Math.floor(seconds / 31536000); if (interval >= 1) { intervalType = 'year'; } else { interval = Math.floor(seconds / 2592000); if (interval >= 1) { intervalType = 'month'; } else { interval = Math.floor(seconds / 86400); if (interval >= 1) { intervalType = 'day'; } else { interval = Math.floor(seconds / 3600); if (interval >= 1) { intervalType = "hour"; } else { interval = Math.floor(seconds / 60); if (interval >= 1) { intervalType = "minute"; } else { interval = seconds; intervalType = "second"; } } } } } if (interval > 1 || interval === 0) { intervalType += 's'; } return interval + ' ' + intervalType; }; var aDay = 24 * 60 * 60 * 1000; console.log(timeSince(new Date(Date.now() - aDay))); console.log(timeSince(new Date(Date.now() - aDay * 2)));

你可以使用Luxon:

DateTime.toRelative()

https://moment.github.io/luxon/api-docs/index.html#datetimetorelative

这里还有一些例子:

const DateTime = luxon.DateTime; // toRelative console.log(DateTime.now().minus({ seconds: 1 }).toRelative()) // 1 second ago console.log(DateTime.now().minus({ seconds: 10 }).toRelative()) // 10 seconds ago console.log(DateTime.now().minus({ days: 2 }).toRelative()) console.log(DateTime.now().minus({ years: 3 }).toRelative()) console.log(DateTime.now().plus({ years: 3 }).toRelative()) console.log(DateTime.now().plus({ days: 2 }).toRelative()) console.log(DateTime.now().plus({ seconds: 1 }).toRelative()) console.log(DateTime.now().plus({ seconds: 10 }).toRelative()) // toRelativeCalendar console.log(DateTime.now().minus({ seconds: 1 }).toRelativeCalendar()) // today console.log(DateTime.now().minus({ seconds: 10 }).toRelativeCalendar()) // today console.log(DateTime.now().minus({ days: 2 }).toRelativeCalendar()) console.log(DateTime.now().minus({ years: 3 }).toRelativeCalendar()) console.log(DateTime.now().plus({ years: 3 }).toRelativeCalendar()) console.log(DateTime.now().plus({ days: 2 }).toRelativeCalendar()) console.log(DateTime.now().plus({ seconds: 1 }).toRelativeCalendar()) console.log(DateTime.now().plus({ seconds: 10 }).toRelativeCalendar()) <script src="https://moment.github.io/luxon/global/luxon.min.js"></script>

                var str = '';
                if(num){

        console.log(timeAgo(new Date()));

        console.log(timeAgo(new Date('Sep 10 1994 13:12:19 GMT+0300 (FLE Daylight Time)')));

我还没有检查(虽然这并不难)，但我认为Stack Exchange站点使用jquery。Timeago插件来创建这些时间字符串。

这个插件使用起来很简单，而且很干净，还能自动更新。

下面是一个简单的例子(来自插件的主页):

First, load jQuery and the plugin: <script src="jquery.min.js" type="text/javascript"></script> <script src="jquery.timeago.js" type="text/javascript"></script> Now, let's attach it to your timestamps on DOM ready: jQuery(document).ready(function() { jQuery("abbr.timeago").timeago(); }); This will turn all abbr elements with a class of timeago and an ISO 8601 timestamp in the title: <abbr class="timeago" title="2008-07-17T09:24:17Z">July 17, 2008</abbr> into something like this: <abbr class="timeago" title="July 17, 2008">about a year ago</abbr> which yields: about a year ago. As time passes, the timestamps will automatically update.

这是我的版本，它既适用于过去的日期，也适用于未来的日期。 它使用Intl。RelativeTimeFormat提供本地化字符串，而不是硬编码字符串。 您可以将日期作为时间戳、日期对象或可解析的日期字符串传递。

/** * Human readable elapsed or remaining time (example: 3 minutes ago) * @param {Date|Number|String} date A Date object, timestamp or string parsable with Date.parse() * @param {Date|Number|String} [nowDate] A Date object, timestamp or string parsable with Date.parse() * @param {Intl.RelativeTimeFormat} [trf] A Intl formater * @return {string} Human readable elapsed or remaining time * @author github.com/victornpb * @see https://stackoverflow.com/a/67338038/938822 */ function fromNow(date, nowDate = Date.now(), rft = new Intl.RelativeTimeFormat(undefined, { numeric: "auto" })) { const SECOND = 1000; const MINUTE = 60 * SECOND; const HOUR = 60 * MINUTE; const DAY = 24 * HOUR; const WEEK = 7 * DAY; const MONTH = 30 * DAY; const YEAR = 365 * DAY; const intervals = [ { ge: YEAR, divisor: YEAR, unit: 'year' }, { ge: MONTH, divisor: MONTH, unit: 'month' }, { ge: WEEK, divisor: WEEK, unit: 'week' }, { ge: DAY, divisor: DAY, unit: 'day' }, { ge: HOUR, divisor: HOUR, unit: 'hour' }, { ge: MINUTE, divisor: MINUTE, unit: 'minute' }, { ge: 30 * SECOND, divisor: SECOND, unit: 'seconds' }, { ge: 0, divisor: 1, text: 'just now' }, ]; const now = typeof nowDate === 'object' ? nowDate.getTime() : new Date(nowDate).getTime(); const diff = now - (typeof date === 'object' ? date : new Date(date)).getTime(); const diffAbs = Math.abs(diff); for (const interval of intervals) { if (diffAbs >= interval.ge) { const x = Math.round(Math.abs(diff) / interval.divisor); const isFuture = diff < 0; return interval.unit ? rft.format(isFuture ? x : -x, interval.unit) : interval.text; } } }

// examples
fromNow('2020-01-01') // 9 months ago
fromNow(161651684156) // 4 days ago
fromNow(new Date()-1) // just now
fromNow(30000 + Date.now()) // in 30 seconds
fromNow(Date.now() + (1000*60*60*24)) // in 1 day
fromNow(new Date('2029-12-01Z00:00:00.000')) // in 9 years

不使用Intl的替代方法。RelativeTimeFormat
