请参阅https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference:Global_Objects:Date:页上的最后一个示例

/* Use a function for the exact format desired... */
function ISODateString(d) {
    function pad(n) {return n<10 ? '0'+n : n}
    return d.getUTCFullYear()+'-'
         + pad(d.getUTCMonth()+1)+'-'
         + pad(d.getUTCDate())+'T'
         + pad(d.getUTCHours())+':'
         + pad(d.getUTCMinutes())+':'
         + pad(d.getUTCSeconds())+'Z'
}

var d = new Date();
console.log(ISODateString(d)); // Prints something like 2009-09-28T19:03:12Z

T后面少了一个+

isoDate: function(msSinceEpoch) {
  var d = new Date(msSinceEpoch);
  return d.getUTCFullYear() + '-' + (d.getUTCMonth() + 1) + '-' + d.getUTCDate() + 'T'
         + d.getUTCHours() + ':' + d.getUTCMinutes() + ':' + d.getUTCSeconds();
}

应该这么做。

对于前导0，你可以从这里使用这个:

function PadDigits(n, totalDigits) 
{ 
    n = n.toString(); 
    var pd = ''; 
    if (totalDigits > n.length) 
    { 
        for (i=0; i < (totalDigits-n.length); i++) 
        { 
            pd += '0'; 
        } 
    } 
    return pd + n.toString(); 
} 

这样使用它:

PadDigits(d.getUTCHours(),2)

toISOString的问题是它只将datetime作为“Z”。

ISO-8601还定义了带小时和分钟时区差异的datetime，格式为2016-07-16T19:20:30+5:30(当时区在UTC之前时)和2016-07-16T19:20:30-01:00(当时区在UTC之后时)。

我不认为使用另一个插件moment.js来完成这么小的任务是个好主意，尤其是当你可以用几行代码就得到它的时候。

一旦有了以小时和分钟为单位的时区偏移量，就可以追加到datetime字符串。

我为此写了一篇博客:http://usefulangle.com/post/30/javascript-get-date-time-with-offset-hours-minutes

var timezone_offset_min = new Date().getTimezoneOffset(), offset_hrs = parseInt(Math.abs(timezone_offset_min / 60)), offset_min = Math.abs(timezone_offset_min % 60), timezone_standard; if (offset_hrs < 10) offset_hrs = '0' + offset_hrs; if (offset_min > 10) offset_min = '0' + offset_min; // getTimezoneOffset returns an offset which is positive if the local timezone is behind UTC and vice-versa. // So add an opposite sign to the offset // If offset is 0, it means timezone is UTC if (timezone_offset_min < 0) timezone_standard = '+' + offset_hrs + ':' + offset_min; else if (timezone_offset_min > 0) timezone_standard = '-' + offset_hrs + ':' + offset_min; else if (timezone_offset_min == 0) timezone_standard = 'Z'; // Timezone difference in hours and minutes // String such as +5:30 or -6:00 or Z console.log(timezone_standard);

用一些糖和现代语法来扩展肖恩伟大而简洁的回答:

// date.js

const getMonthName = (num) => {
  const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Oct', 'Nov', 'Dec'];
  return months[num];
};

const formatDate = (d) => {
  const date = new Date(d);
  const year = date.getFullYear();
  const month = getMonthName(date.getMonth());
  const day = ('0' + date.getDate()).slice(-2);
  const hour = ('0' + date.getHours()).slice(-2);
  const minutes = ('0' + date.getMinutes()).slice(-2);

  return `${year} ${month} ${day}, ${hour}:${minutes}`;
};

module.exports = formatDate;

然后如。

import formatDate = require('./date');

const myDate = "2018-07-24T13:44:46.493Z"; // Actual value from wherever, eg. MongoDB date
console.log(formatDate(myDate)); // 2018 Jul 24, 13:44

我只会使用这个小扩展日期- http://blog.stevenlevithan.com/archives/date-time-format

var date = new Date(msSinceEpoch);
date.format("isoDateTime"); // 2007-06-09T17:46:21

我可以用非常少的代码得到以下的输出。

var ps = new Date('2010-04-02T14:12:07')  ;
ps = ps.toDateString() + " " + ps.getHours() + ":"+ ps.getMinutes() + " hrs";

输出:

Fri Apr 02 2010 19:42 hrs
