Question

So I got my code to work just fine in Chrome. In FF I get the first two alerts with the dates and they’re formatted properly and everything but if a past date is chosen it doesn’t throw the third alert. In IE I get all three alerts but even if I choose a future date. As I mentioned Chrome works as it should so if anyone can provide some insight into making it work across them all that’d be great.

 function check()
{
   var selecteddate = document.form1.selectmonth.value + "-" + document.form1.selectday.value + "-" + document.form1.selectyear.value;
   var d = new Date();
   var today = (d.getMonth()+1) + "-" + d.getDate() + "-" + d.getFullYear();

   // I'd then make some alerts and it'd return the selected date and today with no problem
   alert(selecteddate);
   alert(today)
   //Now for the if statement is where it just stops working. I think maybe I'm doing
   //something wrong just solely in the if statement.
     if(new Date(selecteddate) < new Date(today))
       {
       alert("Past dates are not valid");
       return false;
       }
}
</script>

Answer 1

your dates are invalid to FF, use "/" in place of the "-" for selecteddate and today.

or what about just using

       if(selecteddate < today)

instead of

  if(new Date(selecteddate) < new Date(today))
