javascript date + 7 days

Question

What\'s wrong with this script?

When I set my clock to say 29/04/2011 it adds 36/4/2011 in the week input! but the correct date should be 6/

Answer 1

The simple way to get a date x days in the future is to increment the date:

function addDays(dateObj, numDays) {
  return dateObj.setDate(dateObj.getDate() + numDays);
}

Note that this modifies the supplied date object, e.g.

function addDays(dateObj, numDays) {
   dateObj.setDate(dateObj.getDate() + numDays);
   return dateObj;
}

var now = new Date();
var tomorrow = addDays(new Date(), 1);
var nextWeek = addDays(new Date(), 7);

alert(
    'Today: ' + now +
    '\nTomorrow: ' + tomorrow +
    '\nNext week: ' + nextWeek
);
