如何获取两个日期之间的所有星期日/星期一/星期二? [英] How to get all sundays/mondays/tuesdays between two dates?

问题描述

给出开始日期和结束日期，如何获得所有信息，例如9月1日至11月2日是星期天?

Given a start date and an end date, how can I get all the, e.g. Sundays between September 1st and November 2nd?

注意-不是重复:我不希望计数，而是将各个日期作为javascript日期或momentjs对象(答案链接在另一个因此，问题是要求一个 count )

Note - not a duplicate: I don't want a count, but rather the individual dates as either javascript dates or momentjs objects (The answer linked in the other SO question is asking for a count)

推荐答案

使用循环不断获取下一个星期日的日期，直到您结束日期为止.

Use a loop to continually get the date for next Sunday until you pass the ending date.

var start = moment('2016-09-01'), // Sept. 1st
    end   = moment('2016-11-02'), // Nov. 2nd
    day   = 0;                    // Sunday

var result = [];
var current = start.clone();

while (current.day(7 + day).isBefore(end)) {
  result.push(current.clone());
}

console.log(result.map(m => m.format('LLLL')));
