I have several select boxes and textboxes with the same class and I have the following statement.

if ($('.selTxtClass:visible').val() == "") {
         $('.selTxtClass:visible').focus();
      }
}

If I do an alert with ($('.selTxtClass:visible').val()) it comes as undefined.

I want to check that the value of these elements are empty, but I cant see what is wrong with this if statement, could you give me a hand, please?

Thanks a lot.
