Check That A Date Is Not A Saturday, Sunday Or Monday

[artdocent]

In my submission form, the user selects a date for a lesson. I would like to use javascript to check that the date selected is not a Monday, Saturday, or Sunday. Can anyone help?

 

It would be great if the script also checked that the date is not in the past.

 

I've been sifting through all sorts of JS, and I know it must be possible, but I'm a newbie. Thanks for your help.

Figured it out! I modified script I found in another reply to include checking for the day. My script checks that the date is after today, and it is not a Saturday, Sunday or Monday.

 

 function checkStart()

{

   var v_sDate = document.getElementById("InsertRecordBooking_Date").value;

   var sDate = new Date(v_sDate);

   var nDate = new Date();

   nDate = Date.now();

   var setToday = sDate.getDate() + 1;

   sDate.setDate(setToday);

   

   var setDay = sDate.getDay();

   

   if (sDate<nDate)

      {

         alert("Your requested lesson date is before today.");

         return false;

      }

      else

        {

            if (setDay == 0 || setDay == 1 || setDay == 2)

              {

                  alert("Your requested lesson date is a Saturday, Sunday or Monday. Please choose a new date.");

                  return false;

              }

        }

}   

 

document.getElementById("caspioform").onsubmit=checkStart;
