This works OK, but not if the two dates are the same:

      // check tdate today or ahead
            fdt = new Date(document.rev.tdate.value);
            dnow = new Date();
            if (fdt.getTime() < dnow.getTime()) {
                  alert("Flight date before today.");
                  return false;
            }      

The format of document.rev.tdate is mm/dd/yy.

Why doesn't this work?

replace :  
fdt = new Date(document.rev.tdate.value);

Open in new window

by :  
afdt = document.rev.tdate.value.split("/");
fdt = new Date(2000 + afdt[2], parseInt(afdt[0])-1, afdt[1]); // january = 0, decembre = 11

Open in new window

To leakim971:

Doesn't work. I found out the format was really mm/dd/yyyy, so I changed it to this:

            afdt = document.rev.tdate.value.split("/");
            fdt = new Date(afdt[2], parseInt(afdt[0])-1, afdt[1]); // january = 0, decembre = 11

Still fails for today.

My pleasure!

Add hour, min and second : fdt = new Date(afdt[2], afdt[0]*1-1, afdt[1],23,59,59); // january = 0, decembre = 11
