    在这种情况下可能会有点过火,但如果有机会的话 moment.js 太棒了! 

    moment(yourdate).fromNow()

    我没有查过(虽然不难),但我想 jquery.timeago plugin 创建这些时间字符串 .

    下面是一个快速示例(来自插件的主页):

    首先,加载jQuery和插件:

    <script src="jquery.min.js" type="text/javascript"></script> <script src="jquery.timeago.js" type="text/javascript"></script>

    现在,我们把它贴在你的 DOM上的时间戳就绪:

    jQuery(document).ready(function() {
    jQuery("abbr.timeago").timeago(); });

    abbr 有一类 timeago 8601标题中的时间戳: <abbr class="timeago" title="2008-07-17T09:24:17Z">July 17, 2008</abbr> 变成这样: <abbr class="timeago" title="July 17, 2008">about a year ago</abbr> 收益率:大约一年前。作为时间 通过,时间戳将

    你可能想看看人性化的时间跨度: https://github.com/layam/js_humanized_time_span

    它与框架无关,完全可定制。

    只需下载/包含脚本,然后您就可以执行以下操作: 

    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'

    甚至这个: 

    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"

    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";
}

    否则会显示“75分钟”(1到2小时)。它现在还假设输入日期是Unix时间戳。

    简单易读版本: 

    const NOW = new Date()
const times = [["second", 1], ["minute", 60], ["hour", 3600], ["day", 86400], ["week", 604800], ["month", 2592000], ["year", 31536000]]

function timeAgo(date) {
    var diff = Math.round((NOW - date) / 1000)
    for (var t = 0; t < times.length; t++) {
        if (diff < times[t][1]) {
            if (t == 0) {

    我用js和python编写了一个,用在两个项目中,非常简单: a simple library (less then 2kb) used to format date with *** time ago statement.

    简单,小巧,使用方便,测试良好。

    1. npm install timeago.js

    2. import timeago from 'timeago.js'; // or use script tag

    3. format . 

    var timeagoIns  = timeago();
timeagoIns .format('2016-06-12');

    也可以实时渲染。 

    var timeagoIns = timeago();
timeagoIns.render(document.querySelectorAll('time'));

    尽管这个问题很久以前就被问到了,但是写这个答案的时候希望它能帮助一些人。

    moment().fromNow() 属于 :(请参阅更多信息 here ) 

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

    例如,在我自己的案例中,我想打印 'one month ago' 而不是 'a month ago' ). 在这种情况下,你可以在下面写一些东西。 

    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',

import * as relativeTime from 'dayjs/plugin/relativeTime';

dayjs.extend(relativeTime);
dayjs(dayjs('1990')).fromNow(); // x years ago

    我的解决方案。。

    我是根据其他答案来判断的。 

    function timeSince(date) {
    let minute = 60;
    let hour   = minute * 60;
    let day    = hour   * 24;
    let month  = day    * 30;
    let year   = day    * 365;

    let suffix = ' ago';

    let elapsed = Math.floor((Date.now() - date) / 1000);

    if (elapsed < minute) {
        return 'just now';
    }

    // get an array in the form of [number, string]
    let a = elapsed < hour  && [Math.floor(elapsed / minute), 'minute'] ||
            elapsed < day   && [Math.floor(elapsed / hour), 'hour']     ||
            elapsed < month && [Math.floor(elapsed / day), 'day']       ||
            elapsed < year  && [Math.floor(elapsed / month), 'month']   ||
            [Math.floor(elapsed / year), 'year'];

    // pluralise and append suffix
    return a[0] + ' ' + a[1] + (a[0] === 1 ? '' : 's') + suffix;
}

    我正在寻找答案,几乎实现了其中一个解决方案,但一位同事提醒我检查 react-intl

    所以添加到解决方案中…如果您使用 反应国际 图书馆,他们有 <FormattedRelative> 组件。

    下面是我所做的(对象返回时间单位及其值): 

    function timeSince(post_date, reference)
{
	var reference = reference ? new Date(reference) : new Date(),
		diff = reference - new Date(post_date + ' GMT-0000'),
		date = new Date(diff),
		object = { unit: null, value: null };
	
	if (diff < 86400000)
	{
		var secs  = date.getSeconds(),
			mins  = date.getMinutes(),
			hours = date.getHours(),
			array = [ ['second', secs], ['minute', mins], ['hour', hours] ];
	}
	else
	{
		var days   = date.getDate(),
			weeks  = Math.floor(days / 7),
			months = date.getMonth(),
			years  = date.getFullYear() - 1970,
			array  = [ ['day', days], ['week', weeks], ['month', months], ['year', years] ];
	}

	for (var i = 0; i < array.length; i++)
	{
		array[i][0] += array[i][1] != 1 ? 's' : '';

		object.unit  = array[i][1] >= 1 ? array[i][0] : object.unit;
		object.value = array[i][1] >= 1 ? array[i][1] : object.value;
	}

	return object;
}
