1) On form Submit buton, I call
onsubmit="return val_contact(this);"
2) function val_contact(form) is a function which is getting called on form submit.
3) Inside "val_contact" function, I want to call another function which checks for credit card validity( I have the script for the same) if "CC" is selected.I am using below code, but its not working.(I know it wrong and need guidance on it)
if ( form.PType[1].checked == true )
{
CheckCardNumber(form);
}
Any Help ?? |

| you could try putting an alert just before your if statement to fint out what the value of form.PType[1].checked is, if it does equal true, then I would suggest adding an alert to the CheckCardNumber function to ascertain whether it is getting called. |

Here is it what happens :
if ( form.PType[1].checked == true )
{
alert(form.PType[1].checked);
alert ( "entered" );
CheckCardNumber(form);
alert ( "leaving" );
}
I do get "true" and "entered" message but not "leaving"
It means its calling CheckCardNumber(form) but some problem with CheckCardNumber(form) function only.
Here is the function :
function CheckCardNumber(form) {
var tmpyear;
tmpmonth = form.searchmthED.options[form.searchmthED.selectedIndex].value;
card = form.slctCCType.options[form.slctCCType.selectedIndex].value;
var retval = eval(card + ".checkCardNumber(\"" + form.txtCC_Number.value +
"\", " + tmpyear + ", " + tmpmonth + ");");
alert(retval);
cardname = "";
if (retval)
// The cardnumber has the valid luhn checksum and matches the
// cardtype's rule.
//return true;
else {
// The cardnumber has the valid luhn checksum, but we want to know which
// cardtype it belongs to.
for (var n = 0; n < Cards.size; n++) {
if (Cards[n].checkCardNumber(form.txtCC_Number.value, tmpyear, tmpmonth)) {
cardname = Cards[n].getCardType();
break;
}
}
if (cardname.length > 0) {
alert("This's " + cardname + " number, not " + card + " number.");
return false;
}
else {
alert("This's not a card number.");
return false;
}
}
}

Can I write it as
if ( form.PType[1].checked == true && CheckCardNumber(form))==false)
{
alert("Invalid card");
return false;
}
