So im using javascript to check that a credit card has an expiration that is in the future.

The code works fine in firefox, however in internet explorer, it fails for all dates, even dates years in the future.

Any ideas?

My code is:




var today = new Date(); // get today\\'s date
var thisYear = 1900 + today.getYear();
var thisMonth = 1 + today.getMonth();

var eYear = document.form1.expYear.options[form1.expYear.selectedIndex].value;
var eMonth = document.form1.expMonth.options[form1.expMonth.selectedIndex].value;

if (eYear < thisYear)
{
alert("Your credit card seems to have expired");
return false;
}
if (thisYear < eYear)
{
return true;
}
if (eMonth < thisMonth)
{
alert("Your credit card seems to have expired");
return false;
}
if (thisMonth < eMonth)
{
return true;
}

Use getFullYear() rather than adding 1900 to getYear(),


for dates after 1999 IE returns all 4 digits for the year.

Solved my problem.

Thanks.
