使用javascript格式化DATE（可能正则表达式） [英] Format a DATE with javascript (maybe regex)

问题描述

我正在使用JavaScript和JQuery，我有一个像这样的字符串（不可更改的xml响应）：

I'm using JavaScript and JQuery and I've got a string like this (unchangeable xml response):

var str = "2017-01-08T16:06:52+00:00";

如何转换为这样的日期：

How can I convert to a Date like this:

08 january 2017, 16:06:52

或者至少：

08 01 2017, 16:06:52

我试图使用 .replace（），如：

str = str.replace(/(\d{4})-(\d{2})-(\d{2})T(\d{8}).*/,'$2 $3 $1, $4');

但它不起作用。 :(

But it doesn't works. :(

推荐答案

为此，你可以创建一个 Date（）来自字符串的对象，然后将 Date（）对象公开的方法中的字符串连接在一起。试试这个：

To do this you can create a Date() object from the string, then concatenate together a string from the methods the Date() object exposes. Try this:

var str = "2017-01-08T16:06:52+00:00";
var date = new Date(str);
var months = [ "january", "february", "march", "april", "may", "june", "july", "august", "september", "october", "november", "december" ];

var dateString = ("00" + date.getDate()).slice(-2) + ' ' + months[date.getMonth()] + ' ' + date.getFullYear() + ', ' + ("00" + date.getHours()).slice(-2) + ':' + ("00" + date.getMinutes()).slice(-2) + ':' + ("00" + date.getSeconds()).slice(-2);

console.log(dateString);

请注意，这可以更简单b使用日期格式库（例如MomentJS或DateJS）但是包括整个库来格式化单个日期是相当浪费的。如果您需要在整个网站中反复执行此操作，那么它们可能是值得的。

Note that this can be made simpler by using a date formatting library (such as MomentJS or DateJS) however including an entire library to format a single date is rather wasteful. If you need to do this repeatedly throughout your site then they may be worth it.

另请注意，在英语国家/地区，月份名称应大写，因此请考虑修改该案例的格式。

Also note that in English speaking countries the month names should be capitalised, so consider amending the format for that case.
