如何让 moment.js 以秒为单位显示相对时间? [英] How to make moment.js show relative time in seconds?

问题描述

以下脚本显示了从现在到 2017/07/03 的相对时间.

The following script shows the relative time from now to 2017/07/03.

document.write(moment("20170703 00:00:00", "YYYYMMDD hh:mm:ss").fromNow());

<script src="https://cdn.bootcss.com/moment.js/2.17.1/moment.min.js"></script>

它返回类似 5 个月内 的东西，而我期望类似 在 123456789 秒内.

It returns something like in 5 months, while I expect something like in 123456789 seconds.

推荐答案

您可以使用 diff 指定 'seconds' 单位作为第二个参数:

You can get seconds between two moment objects using diff specifing 'seconds' unit as second parameter:

var mom = moment("20170703 00:00:00", "YYYYMMDD HH:mm:ss");
document.writeln(mom.fromNow());
document.writeln(mom.diff(moment(), 's'));

如果您需要自定义时刻显示相对时间的方式(例如 fromNow() 输出)，您可以使用 relativeTimeThreshold 和 relativeTime.举个例子:

If you need to customize how moment shows relative time (e.g. the fromNow() output) you can use relativeTimeThreshold and relativeTime. Here an example:

var mom = moment("20170703 00:00:00", "YYYYMMDD HH:mm:ss");
console.log(mom.fromNow());

// Change relativeTimeThreshold
moment.relativeTimeThreshold('s', 60*60*24*30*12);

moment.updateLocale('en', {
  relativeTime : {
    s: function (number, withoutSuffix, key, isFuture){
      return number + ' seconds';
    },
  }
});

console.log(mom.fromNow());
