javascript将日期和时间转换为特定格式

javascript convert date and time into specific format

本文关键字：定格 格式 转换 时间 日期 javascript      更新时间：2023-09-26

我是个新手，想把2014-09-25T09:54:00转换成9:54 AM Thu, 25th Sep。。

有人能给我一个用javascript实现的方法吗。

感谢

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..

我为你的案子做了一把小提琴。

它基于这个很棒的教程，它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 */));

正如Phrogz在这里所说：

  1. 将字符串解析为JavaScript Date对象
  2. 根据需要设置Date对象的格式

另请参阅：为什么Date.parse给出错误的结果？以及如何格式化JavaScript日期问题

示例：

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