Converting a datetime string to timestamp in Javascript
提问by Janith Chinthana
Question in brief:
问题简述：
What is the easiest way to convert date-month-year hour(24):minuteto timestamp?
什么是转换的最简单的方法date-month-year hour(24):minute来timestamp？
due to more views add clear question on the top, so that no need to go through background & all if need quick help.
由于更多的观点在顶部添加了明确的问题，因此如果需要快速帮助，则无需查看背景和所有内容。
Background :
背景 ：
I have a simple html table and I used jquery sorterto sort my table columns.
我有一个简单的 html 表，我使用jquery 排序器对我的表列进行排序。
Everything is working fine except a date column which is having following format of data,
除了具有以下数据格式的日期列外，一切正常，
17-09-2013 10:08
date-month-year hour(24):minute
This column is sorting(alphabetically) but not as I expected(date wise). I tried to use a custom parser as follows,
此列正在排序（按字母顺序），但与我预期的不同（按日期排序）。我尝试使用自定义解析器如下，
$.tablesorter.addParser({
id: 'date_column', // my column ID
is: function(s) {
return false;
},
format: function(s) {
var timeInMillis = new Date.parse(s);
return timeInMillis;
},
type: 'numeric'
});
Problem :it fails due to new Date.parse(s).
问题：由于new Date.parse(s).
Question :what is the easiest way to convert date-month-year hour(24):minuteto timestamp? then I can skip var timeInMillis = new Date.parse(s);line.
问题：转换date-month-year hour(24):minute为时间戳的最简单方法是什么？然后我可以跳过var timeInMillis = new Date.parse(s);线。
Thanks
谢谢

Sorry about the confusion about milliseconds, actually it should be the timestampwhich is a number that represents the current time and date.
很抱歉关于 的混淆milliseconds，实际上它应该是timestamp代表当前时间和日期的数字。

Parsing dates is a pain in JavaScript as there's no extensive native support. However you could do something like the following by relying on the Date(year, month, day [, hour, minute, second, millisecond])constructor signature of the Dateobject.
解析日期在 JavaScript 中很痛苦，因为没有广泛的本机支持。但是，您可以通过依赖对象的Date(year, month, day [, hour, minute, second, millisecond])构造函数签名来执行以下操作Date。
var dateString = '17-09-2013 10:08',
dateTimeParts = dateString.split(' '),
timeParts = dateTimeParts[1].split(':'),
dateParts = dateTimeParts[0].split('-'),
date;
date = new Date(dateParts[2], parseInt(dateParts[1], 10) - 1, dateParts[0], timeParts[0], timeParts[1]);
console.log(date.getTime()); //1379426880000
console.log(date); //Tue Sep 17 2013 10:08:00 GMT-0400
You could also use a regular expression with capturing groups to parse the date string in one line.
您还可以使用带有捕获组的正则表达式来解析一行中的日期字符串。
var dateParts = '17-09-2013 10:08'.match(/(\d+)-(\d+)-(\d+) (\d+):(\d+)/);
console.log(dateParts); // ["17-09-2013 10:08", "17", "09", "2013", "10", "08"]

Date.parse()isn't a constructor, its a static method.
Date.parse()不是构造函数，它是一个静态方法。
So, just use
所以，只需使用
var timeInMillis = Date.parse(s);
instead of
代替
var timeInMillis = new Date.parse(s);

Seems like the problem is with the date format.
似乎问题出在日期格式上。
var d = "17-09-2013 10:08",
dArr = d.split('-'),
ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000

For those of us using non-ISO standard date formats, like civilian vernacular 01/01/2001 (mm/dd/YYYY), including time in a 12hour date format with am/pm marks, the following function will return a valid Date object:
对于我们这些使用非 ISO 标准日期格式的人，如民用白话 01/01/2001 (mm/dd/YYYY)，包括带有 am/pm 标记的 12 小时日期格式的时间，以下函数将返回一个有效的 Date 对象：
function convertDate(date) {
// # valid js Date and time object format (YYYY-MM-DDTHH:MM:SS)
var dateTimeParts = date.split(' ');
// # this assumes time format has NO SPACE between time and am/pm marks.
if (dateTimeParts[1].indexOf(' ') == -1 && dateTimeParts[2] === undefined) {
var theTime = dateTimeParts[1];
// # strip out all except numbers and colon
var ampm = theTime.replace(/[0-9:]/g, '');
// # strip out all except letters (for AM/PM)
var time = theTime.replace(/[[^a-zA-Z]/g, '');
if (ampm == 'pm') {
time = time.split(':');
// # if time is 12:00, don't add 12
if (time[0] == 12) {
time = parseInt(time[0]) + ':' + time[1] + ':00';
} else {
time = parseInt(time[0]) + 12 + ':' + time[1] + ':00';
}
} else { // if AM
time = time.split(':');
// # if AM is less than 10 o'clock, add leading zero
if (time[0] < 10) {
time = '0' + time[0] + ':' + time[1] + ':00';
} else {
time = time[0] + ':' + time[1] + ':00';
}
}
}
// # create a new date object from only the date part
var dateObj = new Date(dateTimeParts[0]);
// # add leading zero to date of the month if less than 10
var dayOfMonth = (dateObj.getDate() < 10 ? ("0" + dateObj.getDate()) : dateObj.getDate());
// # parse each date object part and put all parts together
var yearMoDay = dateObj.getFullYear() + '-' + (dateObj.getMonth() + 1) + '-' + dayOfMonth;
// # finally combine re-formatted date and re-formatted time!
var date = new Date(yearMoDay + 'T' + time);
return date;
}
Usage:
用法：
date = convertDate('11/15/2016 2:00pm');
