Vi scrivo perchč ho un'urgente bisogno di aiuto dato che sono completamente ignorante con Javascript
Praticamente ho una textarea in cui inserire una data, accessibile tramite l'utilizzo di un calendario scritto appunto con un Javascript ( praticamente questo )
Ora come ora le freccette mi permettono di andare avanti e indietro solo di mese in mese.
Vorrei aggiungere delle ulteriori freccette per andare avanti e indietro di anno in anno.
Vi giuro che non so proprio dove mettere mani... vorrei inserire questo calendario in una web application in PHP/MySQL dipersč gią molto complessa... se perdo tempo anche con Javascript sono fregato !
Mi date una mano ?
Grazie.
Allego qui il codice
