Ho un form per inserire i libri nel DB di mysql. Vorrei che quando seleziono l'editore dal menù a tendina un codice javascritp mi cattura ID dell'editore e lo passa come valore al menù a tendina Collane. Si può fare senza ricaricare la pagina inserendo solo il codice javascript e utilizzare la funzione onchange sul menù a tendina Editore.
Se sì qualcuno gentilmente potrebbe integrarmi il codice in questo:
<html>
