Moment.js - 获取日期范围之间的所有星期一

Question

I have a date range that looks like this

let start = moment(this.absence.FromDate);
let end = moment(this.absence.ToDate);

The user can decide to deactivate specific week days during that date range, so I have booleans

monday = true;
tuesday = false;
...

I want to create a function that allows me to put all mondays during my date range in an array.

I've looked around on stack but I can only find help for people who need all the monday from a month for example.

Answer 1

You can get next Monday using .day(1) and then loop until your date isBefore your end date adding 7 days for each iteration using add

Here a live sample:

 //let start = moment(this.absence.FromDate); //let end = moment(this.absence.ToDate); // Test values let start = moment(); let end = moment().add(45 , 'd'); var arr = []; // Get "next" monday let tmp = start.clone().day(1); if( tmp.isAfter(start, 'd') ){ arr.push(tmp.format('YYYY-MM-DD')); } while( tmp.isBefore(end) ){ tmp.add(7, 'days'); arr.push(tmp.format('YYYY-MM-DD')); } console.log(arr);
