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。

这是对国际的另一种看法。RelativeTimeFormat

支持过去日期和将来日期 同时接受字符串和日期 易于添加自定义范围(编辑范围) 可以很容易地翻译为Intl.RelativeTimeFormat('ua')

console.log(timeAgo('2021-08-09T15:29:01+0000')); function timeAgo(input) { const date = (input instanceof Date) ? input : new Date(input); const formatter = new Intl.RelativeTimeFormat('en'); const ranges = { years: 3600 * 24 * 365, months: 3600 * 24 * 30, weeks: 3600 * 24 * 7, days: 3600 * 24, hours: 3600, minutes: 60, seconds: 1 }; const secondsElapsed = (date.getTime() - Date.now()) / 1000; for (let key in ranges) { if (ranges[key] < Math.abs(secondsElapsed)) { const delta = secondsElapsed / ranges[key]; return formatter.format(Math.round(delta), key); } } }

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)));

我修改了Sky Sanders的版本。Math.floor(…)操作在if块中计算

       var timeSince = function(date) {
            var seconds = Math.floor((new Date() - date) / 1000);
            var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
            if (seconds < 5){
                return "just now";
            }else if (seconds < 60){
                return seconds + " seconds ago";
            }
            else if (seconds < 3600) {
                minutes = Math.floor(seconds/60)
                if(minutes > 1)
                    return minutes + " minutes ago";
                else
                    return "1 minute ago";
            }
            else if (seconds < 86400) {
                hours = Math.floor(seconds/3600)
                if(hours > 1)
                    return hours + " hours ago";
                else
                    return "1 hour ago";
            }
            //2 days and no more
            else if (seconds < 172800) {
                days = Math.floor(seconds/86400)
                if(days > 1)
                    return days + " days ago";
                else
                    return "1 day ago";
            }
            else{

                //return new Date(time).toLocaleDateString();
                return date.getDate().toString() + " " + months[date.getMonth()] + ", " + date.getFullYear();
            }
        }

    const timeHandler = (time: any) => {
      var a = moment(); //now
      var b = moment.utc(time);
      const sec = a.diff(b, 'seconds');
      const minuts = a.diff(b, 'minutes');
      const hours = a.diff(b, 'hours');
      const days = a.diff(b, 'days');
      const weeks = a.diff(b, 'weeks');
      return weeks == 0
        ? days == 0
          ? hours == 0
            ? minuts == 0
              ? sec >= 0 && `${sec}s ago`
              : `${minuts}m ago`
            : `${hours}h ago`
          : `${days}d ago`
        : `${weeks}w ago`;
    };

console.log(timeHandler('2022-11-11T12:11:06.6103808'))

简单易读版本:

const relativeTimePeriods = [
    [31536000, 'year'],
    [2419200, 'month'],
    [604800, 'week'],
    [86400, 'day'],
    [3600, 'hour'],
    [60, 'minute'],
    [1, 'second']
];

function relativeTime(date, isUtc=true) {
    if (!(date instanceof Date)) date = new Date(date * 1000);
    const seconds = (new Date() - date) / 1000;
    for (let [secondsPer, name] of relativeTimePeriods) {
        if (seconds >= secondsPer) {
            const amount = Math.floor(seconds / secondsPer);
            return `${amount} ${name}${amount ? 's' : ''}s ago`;
        }
    }
    return 'Just now';
}
