使用moment.js从给定日期查找一周中的日期

Question

const from = "2020-07-08";
const to = "2020-07-14";

如何使用 moment.js 在给定的一周内获取“星期四”的日期？ 在下面的示例中，预期的回答将是“星期四”的“2020-07-09”和“星期日”的“2020-07-12”，依此类推。

Answer 1

var new_date = moment("2020-07-08", "YYYY-MM-DD").add(5, 'days');

Answer 2

 let findNextWeekDay = (input_date,day)=> { let the_date = moment(input_date); if (the_date.day(day).isSameOrBefore(input_date)) { return the_date.day(day).add(7,'days'); } return the_date.day(day) } console.log(findNextWeekDay("2021-06-20","Wednesday")); console.log(findNextWeekDay("2021-06-22","Wednesday")); console.log(findNextWeekDay("2021-06-23","Wednesday")); console.log(findNextWeekDay("2021-06-26","Wednesday"));
