获取本周和下一周的日期

Question

I would like to have an array with dates of this current week and the next week. I tried to implement this with a for loop and a while loop but didn't succeed at the moment

getTwoWeeks = () => {

    let twoWeeks = [];
    let days = 14;
    let today = new Date;
    let calcFirst = today.getDate() - today.getDay();
    let firstDayOfWeek = new Date(today.setDate(calcFirst));

    for(let i=0; i<days; i++) {
        twoWeeks.push( new Date(today.setDate(firstDayOfWeek + days[i])) )
    }

    console.log('twoWeeks===',twoWeeks )
}

Answer 1

You can calculate first the Monday of the current week then iterate from there till 14 days.

 const today = new Date(); const dayOfWeek = today.getDay(); const lastMonday = new Date(today.setDate(today.getDate() + (dayOfWeek * -1 + 1))); for (let i = 1, d = lastMonday; i <= 14; i++, d.setDate(d.getDate() + 1)) { console.log(new Date(d)); }

Answer 2

You can do this as follows:

 getTwoWeeks = () => { let twoWeeks = []; let days = 14; let today = new Date(); twoWeeks.push(today) for(let i = 0; i < days-1; i++) { var next = new Date(); next.setDate(today.getDate()+1); twoWeeks.push(next); today = next; } console.log('twoWeeks===',twoWeeks ) } getTwoWeeks();

Answer 3

it looks like your are misusing your index "i" in the for loop. "days" is not an array, it is an integer. Try the following:

 let twoWeeks = []; let days = 14; let today = new Date; let calcDate = new Date(today.setDate(today.getDate() - today.getDay())); for(let i=0; i<days; i++) { calcDate.setDate(calcDate.getDate() + 1) twoWeeks.push(new Date(calcDate)) } console.log(twoWeeks)

Hope this helps!
