Something like this would do:
var now = new Date();
if(entered_year > now.getFullYear() ||
(entered_year == now.getFullYear() && entered_month > (now.getMonth()+1)) ||
(entered_year == now.getFullYear() && entered_month == (now.getMonth()+1) && entered_day > now.getDate())){
// invalid
}
However, the script you are submitting the info to should also check the date, in case the user didn't have JavaScript enabled or changed the computer's date from the OS's control panel.
