Salve a tutti!

Avrei disperatamente bisogno di una mano per capire un problema che mi sta facendo impazzire!!

Quello che vorrei tanto fare, è fare in modo che alla chiusura di una finestra (che in realtà viene nascosta) i video di youtube aggiunti tramite codice incorporato (iframe) si mettesse in stop!

Io non so più che pesci prendere!

Riporto il codice della pagina:

Il problema si trova nella sezione LAVORI, dove ci sono la lista dei progetti principali e poi sotto i progetti già aperti ma nascosti!

Grazie mille!!!
