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!

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

javascript库sugar.js (http://sugarjs.com/)有格式化日期的函数

例子:

Date.create().format('{dd}/{MM}/{yyyy} {hh}:{mm}:{ss}.{fff}')

检查下面的代码和到Date Object, Intl的链接。DateTimeFormat

// var ts_hms = new Date(UTC); // ts_hms.format("%Y-%m-%d %H:%M:%S") // exact format console.log(new Date().toISOString().replace('T', ' ').substring(0, 19)) // other formats console.log(new Date().toUTCString()) console.log(new Date().toLocaleString('en-US')) console.log(new Date().toString()) // log format const parts = new Date().toString().split(' ') console.log([parts[1], parts[2], parts[4]].join(' ')) // intl console.log(new Intl.DateTimeFormat('en-US', {dateStyle: 'long', timeStyle: 'long'}).format(new Date()))

new Date(2015,1,3,15,30).toLocaleString()

//=> 2015-02-03 15:30:00
