[英]Isuue for get all months from a year and get all weeks from a month using Moment js
[英]Get all the start and the end dates of weeks of a year starting 2022 in moment
我想立即以 YYYY-MM-DD (mysql) 格式獲取從 2022 年開始的一年中的所有開始和結束日期。
我希望最終結果看起來像這樣:
[
['2022-01-04', '2022-01-10'],
['2022-01-11', '2022-01-17'],
['2022-01-18', '2022-01-24'],
// ...
['2022-12-24', '2023-01-01'],
['2023-01-02', '2023-01-08'],
// ...
['2023-12-25', '2024-01-01'],
// ...
// Until the end of 2026
];
編輯 1:我嘗試了下面的代碼,但它失敗了:
const moment = require('moment');
const dateFormat = 'YYYY-MM-DD';
const dateToStart = '2022-04-11';
const dateToEnd = '2030-12-29';
function getWeeks() {
const weeks = [];
let currentDate = '2022-04-11';
while (true) {
if (currentDate === dateToStart) {
weeks.push([dateToStart, moment(dateToStart, dateFormat).add(6, 'days').format(dateFormat)]);
} else {
weeks.push([
moment(currentDate, dateFormat).add(1, 'days').format(dateFormat),
moment(currentDate, dateFormat).add(6, 'days').format(dateFormat),
]);
}
currentDate = moment(dateToStart).add(6, 'days').format(dateFormat);
if (currentDate === dateToEnd) break;
}
return weeks;
}
Momentjs 提供了一些非常有用的函數來獲得所需的 output。
isAfter
start.startOf('isoWeek')
和.endOf('isoWeek')
獲取一周的范圍.add(1, 'week')
這個例子應該讓你開始,注意我已經降低了dateToEnd
。
const dateFormat = 'YYYY-MM-DD'; const dateToStart = '2022-04-01'; const dateToEnd = '2023-12-29'; let weeks = []; let momsrt = moment.utc(dateToStart, dateFormat); let momend = moment.utc(dateToEnd, dateFormat); while (momend.isAfter(momsrt)) { weeks.push([ momsrt.startOf('isoWeek').format(dateFormat), momsrt.endOf('isoWeek').format(dateFormat) ]); momsrt.add(1, 'week'); } console.log(weeks);
