moment.js - change format of already formatted past date
提问by Kosmetika
I need to get a past date with moment.js (http://momentjs.com/) which I receive in specific format:
我需要使用我收到的特定格式的moment.js ( http://momentjs.com/)获取过去的日期：
moment('31.10.2013', 'dd.mm.yy');
That returns me a strange response where I see a current date in _doption:
这会返回一个奇怪的响应，我在_d选项中看到当前日期：
// returns
_a: Array[7]
_d: Wed Nov 06 2013 00:10:00 GMT+0200 (EET)
_f: "dd.mm.yy"
_i: "26.10.2013"
_isUTC: false
_l: undefined
_pf: Object
_strict: undefined
I assume that is the problem when I do formatting:
我认为这是我格式化时的问题：
moment('31.10.2013', 'dd.mm.yy').format('YYYY/MM/DD');
// returns current date (why??!)
// "2013/11/06"
So what is wrong here, could I format the past date?
那么这里有什么问题，我可以格式化过去的日期吗？

At first I thought it was the format, but it was actually the format in, lower case means something different than uppercase both in and out.
起初我以为是格式，但实际上是格式，小写的意思与大写的输入和输出不同。
moment('31.10.2013', 'DD.MM.YYYY').format('YYYY/MM/DD')
>> "2013/10/31"
moment('31.10.2013', 'dd.mm.yyyy').format('YYYY/MM/DD')
>> "2013/11/06"
So fix your input mask, not the format.
所以修复你的输入掩码，而不是格式。
