javascript将日期和时间转换为特定格式

Question

我是新手，想将2014-09-25T09:54:00转换为9:54 AM Thu, 25th Sep 。

有人可以建议我用JavaScript做到这一点的方法吗？

谢谢

Answer 1

正如Phrogz 在这里所说：

1. 将字符串解析为JavaScript Date对象。
2. 设置日期对象的格式即可 。

另请参阅： 为什么Date.parse给出不正确的结果？ 以及如何格式化JavaScript日期问题。

例：

var myDate = new Date("2014-09-25T09:54:00")
var myString = myDate.customFormat("#h#:#mm# #AMPM# #DDD#, #D##th# #MMM#");

在这里查看此代码

Answer 2

here is a great JavaScript library that handles this very well, and only 5.5kb minified.

http://momentjs.com/

It looks something like this:


moment().format('MMMM Do YYYY, h:mm:ss a'); // February 25th 2013, 9:54:04 am
moment().subtract('days', 6).calendar(); // "last Tuesday at 9:53 AM"
You can also pass in dates as a String with a format, or a Date object.

var date = new Date();
moment(date); // same as calling moment() with no args

// Passing in a string date
moment("12-25-1995", "MM-DD-YYYY");
Also has great support for languages other then English, like, Russian, Japanese, Arabic, Spanish, etc..

我为你的情况开了个小提琴 。

它基于此处的出色教程，使格式化日期变得非常容易。

JavaScript代码：

 var d_names = new Array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"); var m_names = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec"); var d = new Date(); var curr_date = d.getDate(); var sup = ""; if (curr_date == 1 || curr_date == 21 || curr_date ==31) { sup = "st"; } else if (curr_date == 2 || curr_date == 22) { sup = "nd"; } else if (curr_date == 3 || curr_date == 23) { sup = "rd"; } else { sup = "th"; } var a_p = ""; var curr_hour = d.getHours(); if (curr_hour < 12) { a_p = "AM"; } else { a_p = "PM"; } if (curr_hour == 0) { curr_hour = 12; } if (curr_hour > 12) { curr_hour = curr_hour - 12; } var curr_day = d.getDay(); var curr_min = d.getMinutes(); var curr_month = d.getMonth(); var curr_year = d.getFullYear(); var curr_hour = d.getHours(); alert((curr_hour + " : " + curr_min + " " + a_p)+ (" " + d_names[curr_day] + ", " + curr_date + sup + " " + m_names[curr_month] /* +" " + curr_year */));
