[Required]
[DisplayName("R. F. C.")]
[RegularExpression(@"[a-zA-ZñÑ&]{4}[0-9]{6}[a-zA-ZñÑ0-9&]{2,3}", ErrorMessage = "El RFC no debe contener espacios, -, ni otros caracteres especiales.")]
[StringLength(13)]
public string RFC { get; set; }
and my JS code:
function getInvoicingData() {
var rfc = ...
