Javascript库，用于人性化的相对日期格式 [英] Javascript library for human-friendly relative date formatting

问题描述

我想以人性化的格式显示与当前日期相对的某些日期。

I'd like to display some dates as relative to the current date in a human-friendly format.

人性化的相对日期示例：

Examples of human-friendly relative dates:

• 10秒前
• 
  
• 20分钟以前


• 1天前


• 5周前


• 2个月前

• 10 seconds ago
• 20 minutes from now
• 1 day ago
• 5 weeks ago
• 2 months ago

基本上忠实地保留了最高的数量级（并且优先考虑，只有在通过其中2个时移动单位单位 - 5周，而不是1个月）。

Basically faithfully preserving the highest order of magnitude (and by preference, only shifting up units when passing 2 of those units - 5 weeks instead of 1 month).

虽然我可以住一个图书馆，控制得更少，甚至更友好的日期，如：

Though I could live with a library that had less control and even more friendly dates like:

• 昨天


• 明天


• 上周


• 几分钟前


• 几个小时

• yesterday
• tomorrow
• last week
• a few minutes ago
• in a couple hours

任何流行的图书馆？

推荐答案

自从我写了这个答案之后，最好的图书馆是 moment.js 。

Since I wrote this answer, the best library available is moment.js.

有图书馆可用，但它自己实现它是微不足道的。

There are libraries available, but it is trivial to implement it yourself. Just use a handful of conditions.

假设日期是一个实例化的日期对象，你想比较一下。

Assume date is an instantiated Date object for the time you want to make a comparison against.

// Make a fuzzy time
var delta = Math.round((+new Date - date) / 1000);

var minute = 60,
    hour = minute * 60,
    day = hour * 24,
    week = day * 7;

var fuzzy;

if (delta < 30) {
    fuzzy = 'just then.';
} else if (delta < minute) {
    fuzzy = delta + ' seconds ago.';
} else if (delta < 2 * minute) {
    fuzzy = 'a minute ago.'
} else if (delta < hour) {
    fuzzy = Math.floor(delta / minute) + ' minutes ago.';
} else if (Math.floor(delta / hour) == 1) {
    fuzzy = '1 hour ago.'
} else if (delta < day) {
    fuzzy = Math.floor(delta / hour) + ' hours ago.';
} else if (delta < day * 2) {
    fuzzy = 'yesterday';
}

您需要调整此值才能处理未来日期。

You would need to adapt this to handle future dates.
