Come faccio a far si che la copia del testo negli appunti avvenga anche in Microsoft Internet Explorer (versione precedente alla 9), Opera, Mozilla Firefox, Google Chrome e Safari (ho provato con document.form.emailAddressField.createRange(), come suggerito qui http://help.dottoro.com/ljhcexoj.php, e altre varianti ma...nulla)?
Questo codice funziona in MSIE 11 [...e teoricamente dalla versione 9 e in Opera fino alla versione precedente alla 10.5, http://help.dottoro.com/ljouisvm.php]) ma non in tutti gli altri browser... Qualcuno mi dia una dritta, per favore?
