Get the days of the week from a date - Javascript

  • 772

Create a function which brings me the days of the week from Monday to Sunday :

    weekLabel(current) {
        const week = [];
        const weekFormat = [];
        current.setDate(((current.getDate() - current.getDay()) + 1));
        for (let i = 0; i < 7; i++) {
          week.push(new Date(current));
          current.setDate(current.getDate() + 1);
        }
        week.forEach((w) => {
          weekFormat.push(moment(w).format('DD/MM/YYYY'));
        });
        return weekFormat;
      },

In which current is what the function is waiting for, in this case it passes a date... this works correctly but when I pass it a date of a Sunday it already returns the days of the other week. I know that the week starts from Sunday but I would like to know if I can put it to start from Monday

    The problem is that getDay() will always return 0 on Sunday, a solution could be to include an If so that when it reaches Sunday, I take it as if it were the Seventh day of the week. You can do it in the following way:

    function weekLabel(current) {
const week = [];
const weekFormat = [];

if(current.getDay() == 0){//En los casos en que es domingo, restar como si fuera septimo dia y no cero
    current.setDate(((current.getDate() - 7) + 1));
}else{
    current.setDate(((current.getDate() - current.getDay()) + 1));
}

for (let i = 0; i < 7; i++) {
    week.push(new Date(current));
    current.setDate(current.getDate()+1);
}
week.forEach((w) => {
    weekFormat.push(moment(w).format('DD/MM/YYYY'));
});
return weekFormat;

    }

    I already tried it and it gave results. I hope it helps you
