Well here is what I did. As per Nate's suggestion I put the !== to a != and
still it alerts that the value is not correct. As per Dave suggestion I took
off the () after the return false and it submit the page and does a write of
the word false
Im frustrated, this should be easy, but is proving diffucult
Here is the updated code
var type = target.card_type[target.card_type.selectedIndex].value;
var number = target.card_number.value;
var first_number = number.substring(0,1);
var first_two_numbers = number.substring(0,2);
var first_four_numbers = number.substring(0,4);
if ( type == 'VISA' && parseInt(first_number) != 4){
alert("Invalid Card Number");
return false;
}
if ( type == 'MAST' && 1* parseInt(first_two_numbers) < 50 &&
parseInt(first_two_numbers) > 56 ){
alert("Invalid Card Number");
return false;
}
if (type == 'AMEX' && 1* parseInt(first_two_numbers) != 34 ||
parseInt(first_two_numbers) != 37){
alert("Invalid Card Number");
return false;
}
if(type == 'DISC' && parseInt(first_four_numbers) != 6011){
alert("Invalid Card Number");
return false;
}
