使用Date对象提供的方法，如下所示:

var ts_hms = new Date();

console.log(
    ts_hms.getFullYear() + '-' + 
    ("0" + (ts_hms.getMonth() + 1)).slice(-2) + '-' + 
    ("0" + (ts_hms.getDate())).slice(-2) + ' ' +
    ("0" + ts_hms.getHours()).slice(-2) + ':' +
    ("0" + ts_hms.getMinutes()).slice(-2) + ':' +
    ("0" + ts_hms.getSeconds()).slice(-2));

它看起来很脏，但它应该可以很好地与JavaScript核心方法一起工作

UPDATE 2021-10-06: Added Day.js and remove spurious edit by @ashleedawg UPDATE 2021-04-07: Luxon added by @Tampa. UPDATE 2021-02-28: It should now be noted that Moment.js is no longer being actively developed. It won't disappear in a hurry because it is embedded in so many other things. The website has some recommendations for alternatives and an explanation of why. UPDATE 2017-03-29: Added date-fns, some notes on Moment and Datejs UPDATE 2016-09-14: Added SugarJS which seems to have some excellent date/time functions.

好吧，既然还没有人给出真正的答案，那我的答案就是。

库当然是以标准方式处理日期和时间的最佳选择。在日期/时间计算中有许多边缘情况，因此能够将开发移交给库是非常有用的。

以下是主要Node兼容的时间格式化库列表:

Day.js [added 2021-10-06] "Fast 2kB alternative to Moment.js with the same modern API" Luxon [added 2017-03-29, thanks to Tampa] "A powerful, modern, and friendly wrapper for JavaScript dates and times." - MomentJS rebuilt from the ground up with immutable types, chaining and much more. Moment.js [thanks to Mustafa] "A lightweight (4.3k) javascript date library for parsing, manipulating, and formatting dates" - Includes internationalization, calculations and relative date formats - Update 2017-03-29: Not quite so light-weight any more but still the most comprehensive solution, especially if you need timezone support. - Update 2021-02-28: No longer in active development. date-fns [added 2017-03-29, thanks to Fractalf] Small, fast, works with standard JS date objects. Great alternative to Moment if you don't need timezone support. SugarJS - A general helper library adding much needed features to JavaScripts built-in object types. Includes some excellent looking date/time capabilities. strftime - Just what it says, nice and simple dateutil - This is the one I used to use before MomentJS node-formatdate TimeTraveller - "Time Traveller provides a set of utility methods to deal with dates. From adding and subtracting, to formatting. Time Traveller only extends date objects that it creates, without polluting the global namespace." Tempus [thanks to Dan D] - UPDATE: this can also be used with Node and deployed with npm, see the docs

还有一些非node库:

Datejs[感谢Peter Olson] -没有打包在npm或GitHub中，所以不太容易与Node一起使用-不太推荐，因为自2007年以来没有更新!

从“日期格式”导入日期格式; var what = new Date（）

<footer>
    <span>{props.data.footer_desc} <a href={props.data.footer_link}>{props.data.footer_text_link}</a> {" "}
    ({day = dateFormat(props.data.updatedAt, "yyyy")})
            </span>
</footer>

有一个转换库:

npm install dateformat

然后写下你的要求:

var dateFormat = require('dateformat');

然后绑定值:

var day=dateFormat(new Date(), "yyyy-mm-dd h:MM:ss");

看到dateformat

在反映你的时区时，你可以使用这个

新日期() 新日期( 时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制 ); var curr_time = dateString.toISOString()。代表(“T”，“”)。substr (0, 19); 游戏机。log (curr_time);

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进行轻微修改:

new Date().toISOString()
> '2012-11-04T14:51:06.157Z'

所以只要剪掉一些东西，你就搞定了:

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必然是UTC(也由第一个结果的末尾Z表示)，因此默认情况下得到UTC(总是一件好事)。
