Hello

I don't program in javascript so I was hoping I might be able to get a bit of help on this forum. When a user loads a webpage I need some javascript that will be able to find out the date of the Monday and the Sunday of the current week. So for example today is Wed 12th of June. The javascript would work out that the date of Monday of the c urrent week is the 10th of June and the date of Sunday is 16th June. If the user loaded the page on Monday 10th of June then the javascript would work out that the date of the Monday of the current week is 10th June. If the user loaded the page on Sunday 16th June then the javascript would work out that the Sunday of the current week is 16th June

Thanks a lot

function getMonday(d) {
  d = new Date(d);
  var day = d.getDay(),
      diff = d.getDate() - day + (day == 0 ? -6 : 1);
  return new Date(d.setDate(diff));
}

function getSunday) {
  d = new Date(d);
  var day = d.getDay(),
      diff = d.getDate() - day;
  return new Date(d.setDate(diff));
}
