Javascript date formatting Fri Jun 21 00:00:00 UTC+0100 2013 to iso 8601 (2013-06-21)
提问by Joshua Holden
Please advise:
请指教：
Is there a way without regex or string replaces and so forth to convert a simple date such as:
有没有办法不用正则表达式或字符串替换等来转换一个简单的日期，例如：
Fri Jun 21 00:00:00 UTC+0100 2013
To a ISO8601formatted date yy-mm-dd?
到 ISO8601格式的日期 yy-mm-dd？
PS: 8601date only, not date time.
PS：8601仅日期，而不是日期时间。

Without regexes or string replaces? Yes, assuming that the format is fixed you could use .slice()and/or .substr()to extract the particular bits you need and rearrange them (unless such methods fall into your category of "and so forth"):
没有正则表达式或字符串替换？是的，假设格式是固定的，您可以使用.slice()和/或.substr()提取您需要的特定位并重新排列它们（除非这些方法属于您的“等等”类别）：
var input = "Fri Jun 21 00:00:00 UTC+0100 2013";
var year = input.slice(-4),
month = ['Jan','Feb','Mar','Apr','May','Jun',
'Jul','Aug','Sep','Oct','Nov','Dec'].indexOf(input.substr(4,3))+1,
day = input.substr(8,2);
var output = year + '-' + (month<10?'0':'') + month + '-' + day;
Or you couldgo ahead and get silly with a regex replace:
或者您可以继续使用正则表达式替换变得愚蠢：
var output = input.replace(/^[^\s]+\s([^\s]+)\s(\d+)\s.*(\d{4})$/,function(m,p1,p2,p3) {
var month = ['Jan','Feb','Mar','Apr','May','Jun',
'Jul','Aug','Sep','Oct','Nov','Dec'].indexOf(p1)+1;
return p3 + '-' + (month<10?'0':'') + month + '-' + (p2.length===1?'0':'') + p2;
});
Of course you'd probably want to wrap such code in a reformatDate()method.
当然，您可能希望将此类代码包装在一个reformatDate()方法中。
(For a "simple" reformatting of a date string,the Dateobject and its methods aren't particularly helpful unless the starting format is one recognised by Date.parse().)
（对于“简单的”重新格式化的日期的串，该Date对象及其方法，没有特别有用除非起始格式由识别一个Date.parse()。）

Use moment.js http://momentjs.com/
使用moment.js http://momentjs.com/
moment(new Date(), "YYYY-MM-DD HH:mm Z");
or:
或者：
var date = moment("Fri Jun 21 00:00:00 UTC+0100 2013");
moment("Fri Jun 21 00:00:00 UTC+0100 2013", "YYYY-MM-DD HH:mm Z");
You can parse it and format it very easily whatever way you want http://momentjs.com/docs/it is compatible with ISO-8601 dates for parsing as well.
你可以很容易地解析它并以任何你想要的方式格式化它http://momentjs.com/docs/它也兼容 ISO-8601 日期进行解析。

Yes !
是的 ！
the date function in javascript.
javascript中的日期函数。
var d = new Date("Fri Jun 21 00:00:00 UTC+0100 2013")
alert( d.getFullYear() + '-' + d.getUTCMonth() + '-' + d.getUTCDay())
2 lines of code :)
2行代码:)

Why dont you try to use the getfunctions, like getDate(), getMonth(), etc. For example:
你为什么不尝试使用get功能，如getDate()，getMonth()等。例如：
var today = new Date();
var d1 = new Date();
alert(d1);
var date = d1.getDate();
var month = d1.getMonth() + 1;
var year = d1.getFullYear();
Then configure the string the way you want it to appear...!
然后按照您希望它出现的方式配置字符串...！
