如何使用 NodeJS 将 UTC 日期格式化为 `YYYY-MM-DD hh:mm:ss` 字符串?
使用 NodeJS,我想将 Date
格式化为以下字符串格式:
Using NodeJS, I want to format a Date
into the following string format:
var ts_hms = new Date(UTC);
ts_hms.format("%Y-%m-%d %H:%M:%S");
我该怎么做?
推荐答案
如果你使用 Node.js,你肯定有 EcmaScript 5,所以 Date 有一个 toISOString
方法.您要求对 ISO8601 稍作修改:
If you're using Node.js, you're sure to have EcmaScript 5, and so Date has a toISOString
method. You're asking for a slight modification of ISO8601:
new Date().toISOString()
> '2012-11-04T14:51:06.157Z'
所以只要删掉一些东西,就可以了:
So just cut a few things out, and you're set:
new Date().toISOString().
replace(/T/, ' '). // replace T with a space
replace(/..+/, '') // delete the dot and everything after
> '2012-11-04 14:55:45'
或者,在一行中:new Date().toISOString().replace(/T/, ' ').replace(/..+/, '')
ISO8601 必须是 UTC(也由第一个结果的尾随 Z 表示),因此默认情况下您会得到 UTC(总是一件好事).
ISO8601 is necessarily UTC (also indicated by the trailing Z on the first result), so you get UTC by default (always a good thing).
