给定特定的日期或时间戳，提取特定月份的星期几和星期几 [英] Extract day and week number of a specific month given a specific date or time stamp

问题描述

如果可能的话，最好在jQuery中使用，否则任何Javascript都可以使用.

Preferred in jQuery, if possible, otherwise any Javascript will work.

我想获取给定特定日期或时间戳记的月份的星期几.

I'd like to get the day and week number of month given a specific date or timestamp.

例如

2010-10-26将返回星期二和4作为星期数

2010-10-26 would return Tuesday and 4 as the week number

2010-11-11将返回星期四和2作为星期数

2010-11-11 would return Thursday and 2 as the week number

推荐答案

您需要查看 JavaScript日期对象.

要获取星期几，您需要执行以下操作:

To get the day of the week, you need to do something like the following:

var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];

var myDate = new Date('2010-10-26');

var dayOfWeek = days[myDate.getDay()]; // dayOfWeek == 'Tuesday'

这是因为getDay()返回的是数字0-6，而不是字符串.这很有用，例如进行国际化.

This is because getDay() returns a number 0-6 rather than a string. This is useful e.g. for internationalisation.

您的其他要求(一个月中的第几周)将需要自定义编码-使用本地JS日期对象无法完成.

Your other requirement (week of month) would need custom coding -- it can't be done using the native JS date object.
