const createdAt = moment(created_at).fromNow()

量身定制的解决方案

        const duration = moment.duration(moment().diff(moment(created_at)))
        const createdAt = duration.as('week') >= 1
          ? `${Math.floor(duration.as('week'))} week(s)`
          : duration.as('day') >= 1
            ? `${Math.floor(duration.as('day'))} day(s)`
            : duration.as('hour') >= 1
              ? `${Math.floor(duration.as('hour'))} hour(s)`
              : `${Math.floor(duration.as('minute'))} minute(s)`

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"

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();
            }
        }

虽然这个问题是很久以前问过的，但写下这个答案希望它能帮助到一些人。

传递您想要开始计数的日期。使用momentjs的moment().fromNow():(在这里查看更多信息)

getRelativeTime(date) {
    const d = new Date(date * 1000);
    return moment(d).fromNow();
}

如果您想更改日期fromNow提供的信息，请编写自定义相对时间为时刻。

例如，在我自己的例子中，我想打印'one month ago'而不是'a month ago'(由moment(d). fromnow()提供)。在这种情况下，你可以写出下面给出的内容。

moment.updateLocale('en', {
    relativeTime: {
        future: 'in %s',
        past: '%s ago',
        s: 'a few seconds',
        ss: '%d seconds',
        m: '1 m',
        mm: '%d minutes',
        h: '1 h',
        hh: '%d hours',
        d: '1 d',
        dd: '%d days',
        M: '1 month',
        MM: '%d months',
        y: '1 y',
        yy: '%d years'
    }
});

注意:我是在Angular 6中为项目编写代码的

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)));
