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();
            }
        }

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)));

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。

我用js和python写了一个，在两个项目中使用，非常漂亮和简单:一个简单的库(少于2kb)，用于*** time ago语句格式化日期。

简单，小巧，易于使用，并且经过良好测试。

NPM安装timeago.js 从timeago.js导入timeago;//或使用脚本标签 使用API格式。

示例:

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

你也可以实时渲染。

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

function timeSince(date) { var seconds = Math.floor((new Date() - date) / 1000); var interval = seconds / 31536000; if (interval > 1) { return Math.floor(interval) + " years"; } interval = seconds / 2592000; if (interval > 1) { return Math.floor(interval) + " months"; } interval = seconds / 86400; if (interval > 1) { return Math.floor(interval) + " days"; } interval = seconds / 3600; if (interval > 1) { return Math.floor(interval) + " hours"; } interval = seconds / 60; if (interval > 1) { return Math.floor(interval) + " minutes"; } return Math.floor(seconds) + " seconds"; } var aDay = 24*60*60*1000; console.log(timeSince(new Date(Date.now()-aDay))); console.log(timeSince(new Date(Date.now()-aDay*2)));

在这种情况下可能有点过头了，但如果有机会，moment.js真的很棒!

js是一个javascript datetime库，在这种情况下使用它，你需要做:

moment(yourdate).fromNow()

2018附录:Luxon是一个新的现代图书馆，可能值得一看!

2022年附录:Day.js是一个较新的库，比Luxon轻80%左右，具有类似的功能。
