Introduzione

Questo capitolo contiene una breve reference per tutti i metodi, proprietà, ed eventi disponibili attraverso l'oggetto window del DOM. L'oggetto window implementa l'interfacciawindow , la quale eredita dall'interfaccia AbstractView.

L'oggetto window rappresenta una finestra, contenente un documento DOM. La proprietà document punta ad un DOM document ( documento DOM ) caricato in quella pagina

Ogni tab che viene aperta contiene il suo personale oggetto window; ciò significa che l'oggetto window non è condiviso fra le varie tab aperte nella stessa finestra. Solo due metodi vengono condivisi dai vari oggetti window presenti in una stessa finestra, e sono i metodi window.resizeTo e window.resizeBy.
