vindicia.setup(), you cannot call a validation function directly. Instead, your validation function is called for you. Specify the validation function in vindicia.setup() as follows:
onSubmitEvent: function(theForm) {
return merchantValidate(theForm);
},
Submit button, merchantValidate(theForm) is called. You must return a boolean value. True causes the form to be submitted, false blocks submission of the form.
Structure your validation function as follows:
function merchantValidate(theform)
{
if (!vindicia.isValid('vin_PaymentMethod_creditCard_account'))
{
// sensitive field
alert('Please enter a valid credit card before submitting');
return false;
}
if (!vindicia.isValid('vin_PaymentMethod_creditCard_expirationDate'))
{
// sensitive field
alert('Please enter a valid expiration date YYYYMM before submitting');
return false;
}
if (theform.vin_PaymentMethod_accountHolderName.value.length == 0)
{
// non sensitive field
alert('Please enter the Account Name');
return false;
}
if (vindicia.cardType == "amex" &&
vindicia.dataLength('vin_PaymentMethod_nameValues_cvn') != 4)
{
alert("American Express CVV must be 4 digits");
return false
}
return true;
}
