用于人性化相对日期格式的 Javascript 库 [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关的一些日期.
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 分钟后
- 1 天前
- 5 周前
- 2 个月前
基本上忠实地保留最高数量级(并且优先选择仅在超过其中 2 个单位时上调单位 - 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).
虽然我可以和一个控制更少、日期更友好的图书馆一起生活,比如:
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
- 几个小时后
有什么流行的库吗?
推荐答案
自从我写了这个答案,一个众所周知的可用库是 moment.js.
Since I wrote this answer, a well known library available is moment.js.
有可用的库,但自己实现它是微不足道的.只需使用一些条件即可.
There are libraries available, but it is trivial to implement it yourself. Just use a handful of conditions.
假设 date
是您要进行比较的时间的实例化 Date
对象.
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';
}
您需要对此进行调整以处理未来的日期.
You would need to adapt this to handle future dates.
