在JS / Prototype中获取一个月的几天 [英] get days of a month in JS/Prototype

问题描述

我正在寻找一种方法，它返回给定月份的所有日子。在标准的 date（）函数中找不到任何帮助。

I´m looking for a method, which returns all days of a given month. I couldn't find anything helpful at the standard date() functions.

ie：

getDays(2010-05) // returns something like:

{ day:'Saturday', date:'2010-01-05' },
{ day:'Sunday', date:'2010-02-05' },
{ day:'Monday', date:'2010-03-05' }[...]

Just the day of the first day of the month may (saturday, 01) and the last (monday, 31) would be great, too.

推荐答案

你可以很容易地做到这一点。 JavaScriptDate对象对于这样的事情是非常有帮助的：

You can do this yourself pretty easily. The Javascript "Date" object is a great help for things like this:

function listDays(monthNumber) {
  var days = [],
    today = new Date(),
    d = new Date(today.getFullYear(), monthNumber, 1);

  while (d.getMonth() == monthNumber) {
    days.push({ "date": d.getDate(), "weekday": d.getDay()});
    d.setDate(d.getDate() + 1);
  }
  return days;
}

只能在数字上返回月份的日子，但很容易使用一系列日期名称来扩展：

That only returns the days in the month numerically, but it'd be easy to extend with an array of day-of-week names:

function listDays(monthNumber) {
  var days = [],
    today = new Date(),
    d = new Date(today.getFullYear(), monthNumber, 1),
    weekdays = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];

  while (d.getMonth() == monthNumber) {
    days.push({ "date": d.getDate(), "weekday": weekdays[d.getDay()]});
    d.setDate(d.getDate() + 1);
  }
  return days;
}
