Cleaner way to convert dd-mm-yyyy to mm-dd-yyyy format in Javascript
提问by Sparky
I have this date as string with me 15-07-2011 which is in the format dd-mm-yyyy. I needed to create a Dateobject from this string. So I have to convert the date in dd-mm-yyyyto mm-dd-yyyyformat.
我把这个日期作为字符串 15-07-2011，格式为dd-mm-yyyy. 我需要Date从这个字符串创建一个对象。所以我必须将日期转换dd-mm-yyyy为mm-dd-yyyy格式。
What I did is the following.
我所做的是以下内容。
var myDate = '15-07-2011';
var chunks = myDate.split('-');
var formattedDate = chunks[1]+'-'+chunks[0]+'-'+chunks[2];
Now I got the string 07-15-2011 which is in mm-dd-yyyyformat, and I can pass it to the Date()constructor to create a Dateobject. I wish to know if there is any cleaner way to do this.
现在我得到了格式为 07-15-2011 的字符串mm-dd-yyyy，我可以将它传递给Date()构造函数来创建一个Date对象。我想知道是否有任何更清洁的方法来做到这一点。

That looks very clean as it is.
看起来很干净。

Re-arranging chunks of a string is a perfectly "clean" and legitimate way to change a date format.
重新排列字符串块是一种完全“干净”且合法的更改日期格式的方式。
However, if you're not happy with that (maybe you want to know that the string you're re-arranging is actually a valid date?), then I recommend you look at DateJS, which is a full-featured date handling library for Javascript.
但是，如果您对此不满意（也许您想知道您重新排列的字符串实际上是一个有效日期？），那么我建议您查看DateJS，它是一个功能齐全的日期处理库对于 Javascript。

Depends what you mean by cleaner
取决于您所说的清洁剂是什么意思
var myDate = '15-07-2011';
var chunks = myDate.split('-');
var formattedDate = [chunks[1],chunks[0],chunks[2]].join("-");
Some would say this is cleaner, but it does essentially the same.
有人会说这更干净，但它的作用基本相同。

var formattedDate = chunks[1] + '-' + chunks[0] + '-' + chunks.pop();

If you wanted to you could cut down on some variables.
如果你愿意，你可以减少一些变量。
var date = '15-07-2011'.split('-');
date = date[1]+'-'+date[0]+'-'+date[2];
If you want a one liner
如果你想要一个班轮
var date = '15-07-2011'.replace(/(\d*)-(\d*)-(\d*)/,'--')

var c = '01-01-2011'.split('-');
var d = new Date(c[2],c[1]-1,c[0]);

I'll add my opinion that your solution is perfectly valid, but if you want something different:
我将补充我的观点，即您的解决方案是完全有效的，但如果您想要不同的东西：
var myDate = '15-07-2011';
myDate.split('-').reverse().join('-');
Will give you '2011-07-15' which, although not exactly what you asked for, will be parsed properly by Date
会给你“2011-07-15”，虽然不是你所要求的，但会被正确解析 Date

I wrote a library for parsing, manipulating, and formatting strings named Moment.js
我编写了一个名为Moment.js 的用于解析、操作和格式化字符串的库
var date = moment('15-07-2011', 'DD-MM-YYYY').format('DD-MM-YYYY');
