遍历NodeJS中的一系列日期 [英] Iterate through a range of dates in NodeJS

问题描述

我想遍历一系列的日历日期，每次迭代为+1天。我会使用Java中的JodaTime构建的东西-NodeJS中是否有类似的东西？

I would like to iterate through a range of calender dates, each iteration is +1 day. I would use something built around JodaTime in Java - is there something similar in NodeJS?

推荐答案

您可以使用 moment.js 在node.js应用程序中。

You can use moment.js in a node.js application.

npm install moment

然后，您可以很容易地做到这一点：

Then you can very easily do this:

var moment = require('moment');

var a = moment('2013-01-01');
var b = moment('2013-06-01');

// If you want an exclusive end date (half-open interval)
for (var m = moment(a); m.isBefore(b); m.add(1, 'days')) {
  console.log(m.format('YYYY-MM-DD'));
}

// If you want an inclusive end date (fully-closed interval)
for (var m = moment(a); m.diff(b, 'days') <= 0; m.add(1, 'days')) {
  console.log(m.format('YYYY-MM-DD'));
}

嗯...这看起来很像您已经在自己的代码中写的代码自己的答案。 Moment.js是一个更受欢迎的库，具有大量功能，但是我想知道哪个库的性能更好？也许您可以测试并告诉我们。 ：）

Hmmm... this looks a lot like the code you already wrote in your own answer. Moment.js is a more popular library has tons of features, but I wonder which one performs better? Perhaps you can test and let us know. :)

但是这些都不比JodaTime做得好。为此，您需要一个在JavaScript中实现TZDB的库。我列出了其中一些。

But neither of these do as much as JodaTime. For that, you need a library that implements the TZDB in JavaScript. I list some of those here.

另外，请当心通常用于 JavaScript日期问题。这也会影响NodeJS。

Also, watch out for problems with JavaScript dates in general. This affects NodeJS as well.
