问题描述

I'd like to keep this solution as clean and minimal as possible. If you need anything else please let me know! Thanks!

推荐答案

datejs 可以解析以下内容，你可能想尝试一下。

datejs could parse following, you might want to try out.

Date.parse('1997-07-16T19:20:15')           // ISO 8601 Formats
Date.parse('1997-07-16T19:20:30+01:00')     // ISO 8601 with Timezone offset

编辑：正则表达式版本

x = "2011-01-28T19:30:00EST"

MM = ["January", "February","March","April","May","June","July","August","September","October","November", "December"]

xx = x.replace(
    /(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):\d{2}(\w{3})/,
    function($0,$1,$2,$3,$4,$5,$6){
        return MM[$2-1]+" "+$3+", "+$1+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6
    }
)

结果

January 28, 2011 - 7:30PM EST

编辑2：我将时区更改为EST，现在我已经关注

I changed my timezone to EST and now I got following

x = "2011-01-28T19:30:00-05:00"

MM = {Jan:"January", Feb:"February", Mar:"March", Apr:"April", May:"May", Jun:"June", Jul:"July", Aug:"August", Sep:"September", Oct:"October", Nov:"November", Dec:"December"}

xx = String(new Date(x)).replace(
    /\w{3} (\w{3}) (\d{2}) (\d{4}) (\d{2}):(\d{2}):[^(]+\(([A-Z]{3})\)/,
    function($0,$1,$2,$3,$4,$5,$6){
        return MM[$1]+" "+$2+", "+$3+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6 
    }
)

返回

January 28, 2011 - 7:30PM EST

p>

Basically

String(new Date(x))

返回

Fri Jan 28 2011 19:30:00 GMT-0500 (EST)

正则表达式零件只需将上述字符串转换为所需的格式。

regex parts just converting above string to your required format.

January 28, 2011 - 7:30PM EST
