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

/** * 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() * @return {string} Human readable elapsed or remaining time * @author github.com/victornpb * @see https://stackoverflow.com/a/67338038/938822 */ function fromNow(date) { 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 units = [ { max: 30 * SECOND, divisor: 1, past1: 'just now', pastN: 'just now', future1: 'just now', futureN: 'just now' }, { max: MINUTE, divisor: SECOND, past1: 'a second ago', pastN: '# seconds ago', future1: 'in a second', futureN: 'in # seconds' }, { max: HOUR, divisor: MINUTE, past1: 'a minute ago', pastN: '# minutes ago', future1: 'in a minute', futureN: 'in # minutes' }, { max: DAY, divisor: HOUR, past1: 'an hour ago', pastN: '# hours ago', future1: 'in an hour', futureN: 'in # hours' }, { max: WEEK, divisor: DAY, past1: 'yesterday', pastN: '# days ago', future1: 'tomorrow', futureN: 'in # days' }, { max: 4 * WEEK, divisor: WEEK, past1: 'last week', pastN: '# weeks ago', future1: 'in a week', futureN: 'in # weeks' }, { max: YEAR, divisor: MONTH, past1: 'last month', pastN: '# months ago', future1: 'in a month', futureN: 'in # months' }, { max: 100 * YEAR, divisor: YEAR, past1: 'last year', pastN: '# years ago', future1: 'in a year', futureN: 'in # years' }, { max: 1000 * YEAR, divisor: 100 * YEAR, past1: 'last century', pastN: '# centuries ago', future1: 'in a century', futureN: 'in # centuries' }, { max: Infinity, divisor: 1000 * YEAR, past1: 'last millennium', pastN: '# millennia ago', future1: 'in a millennium', futureN: 'in # millennia' }, ]; const diff = Date.now() - (typeof date === 'object' ? date : new Date(date)).getTime(); const diffAbs = Math.abs(diff); for (const unit of units) { if (diffAbs < unit.max) { const isFuture = diff < 0; const x = Math.round(Math.abs(diff) / unit.divisor); if (x <= 1) return isFuture ? unit.future1 : unit.past1; return (isFuture ? unit.futureN : unit.pastN).replace('#', x); } } };

将上面的函数更改为

function timeSince(date) {

    var seconds = Math.floor(((new Date().getTime()/1000) - date)),
    interval = Math.floor(seconds / 31536000);

    if (interval > 1) return interval + "y";

    interval = Math.floor(seconds / 2592000);
    if (interval > 1) return interval + "m";

    interval = Math.floor(seconds / 86400);
    if (interval >= 1) return interval + "d";

    interval = Math.floor(seconds / 3600);
    if (interval >= 1) return interval + "h";

    interval = Math.floor(seconds / 60);
    if (interval > 1) return interval + "m ";

    return Math.floor(seconds) + "s";
}

否则它会显示“75分钟”(介于1到2小时之间)。它现在还假定输入日期是Unix时间戳。

您可能需要查看humanized_time_span: https://github.com/layam/js_humanized_time_span

它与框架无关，并且完全可定制。

只需下载/包含脚本，然后你可以这样做:

humanized_time_span("2011-05-11 12:00:00")  
   => '3 hours ago'

humanized_time_span("2011-05-11 12:00:00", "2011-05-11 16:00:00)  
   => '4 hours ago'

甚至是这样:

var custom_date_formats = {
  past: [
    { ceiling: 60, text: "less than a minute ago" },
    { ceiling: 86400, text: "$hours hours, $minutes minutes and $seconds seconds ago" },
    { ceiling: null, text: "$years years ago" }
  ],
  future: [
    { ceiling: 60, text: "in less than a minute" },
    { ceiling: 86400, text: "in $hours hours, $minutes minutes and $seconds seconds time" },
    { ceiling: null, text: "in $years years" }
  ]
}

humanized_time_span("2010/09/10 10:00:00", "2010/09/10 10:00:05", custom_date_formats) 
  => "less than a minute ago"

这将显示你过去和以前的时间格式，如“2天前”“从现在开始10分钟”，你可以传递给它一个日期对象，数字时间戳或日期字符串

function time_ago(time) { switch (typeof time) { case 'number': break; case 'string': time = +new Date(time); break; case 'object': if (time.constructor === Date) time = time.getTime(); break; default: time = +new Date(); } var time_formats = [ [60, 'seconds', 1], // 60 [120, '1 minute ago', '1 minute from now'], // 60*2 [3600, 'minutes', 60], // 60*60, 60 [7200, '1 hour ago', '1 hour from now'], // 60*60*2 [86400, 'hours', 3600], // 60*60*24, 60*60 [172800, 'Yesterday', 'Tomorrow'], // 60*60*24*2 [604800, 'days', 86400], // 60*60*24*7, 60*60*24 [1209600, 'Last week', 'Next week'], // 60*60*24*7*4*2 [2419200, 'weeks', 604800], // 60*60*24*7*4, 60*60*24*7 [4838400, 'Last month', 'Next month'], // 60*60*24*7*4*2 [29030400, 'months', 2419200], // 60*60*24*7*4*12, 60*60*24*7*4 [58060800, 'Last year', 'Next year'], // 60*60*24*7*4*12*2 [2903040000, 'years', 29030400], // 60*60*24*7*4*12*100, 60*60*24*7*4*12 [5806080000, 'Last century', 'Next century'], // 60*60*24*7*4*12*100*2 [58060800000, 'centuries', 2903040000] // 60*60*24*7*4*12*100*20, 60*60*24*7*4*12*100 ]; var seconds = (+new Date() - time) / 1000, token = 'ago', list_choice = 1; if (seconds == 0) { return 'Just now' } if (seconds < 0) { seconds = Math.abs(seconds); token = 'from now'; list_choice = 2; } var i = 0, format; while (format = time_formats[i++]) if (seconds < format[0]) { if (typeof format[2] == 'string') return format[list_choice]; else return Math.floor(seconds / format[2]) + ' ' + format[1] + ' ' + token; } return time; } var aDay = 24 * 60 * 60 * 1000; console.log(time_ago(new Date(Date.now() - aDay))); console.log(time_ago(new Date(Date.now() - aDay * 2)));
