Call the above function in another webresource to validate the fields

Add the below webresource onChange of the field("iban") on the payment form
-----------------------------------------------------------------------------------------
function IBANCheck() {
var AccountNumber = Xrm.Page.getAttribute("iban").getValue();
if(AccountNumber != null)
{
var status = IBAN.isValid(AccountNumber );
//alert(status);
if(status ==true)
Xrm.Page.getAttribute("ibanvalidation").setValue(true);
else
Xrm.Page.getAttribute("ibanvalidation").setValue(false);
