Ho elaborato uno script che ho scaricato, che mi scrive su una select multipla le province della regione selezionata nella prima select.
Tuttavia io vorrei che la seconda select non abbia come name: Cities ma Cities[]
in modo tale che in un successivo form io possa recuperare in un array tutte le selezioni della select multipla.
Come posso aggiustare questo script ???
<script language="JavaScript">
