我的问题是:如何格式化从MongoDB返回的Jade(或Mongoose或Node.JS)中的日期?

推荐答案

JavaScript内置了对日期的支持.首先，将您的字符串放入Date对象中:

JavaScript has built-in support for dates. First, to get your string into a Date object:

date =  new Date('Thu Dec 29 2011 20:14:56 GMT-0600 (CST)')

现在您可以在日期上使用各种方法来获取所需的数据:

Now you can use various methods on the date to get the data you need:

date.toDateString() // "Thu Dec 29 2011"
date.toUTCString()  // "Fri, 30 Dec 2011 02:14:56 GMT"
date.getMonth()     // 11
date.getDate()      // 29
date.getFullYear()  // 2011

您可以在MDN参考网站上看到更多方法.您可以使用这些方法来构建所需的任何类型的字符串.

You can see more methods on the MDN reference site. You can use these methods to build any kind of string you want.
