Window

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'interfaccia window , la quale eredita dall'interfaccia AbstractView.

L'oggetto window rappresenta l'intera finestra. Tipicamente window contiene l'elemento document come figlio, fornisce accesso agli oggetti window.navigator e window.screen per manipolare l'ambiente di navigazione, e prevede un numero di proprietà speciali per accedere al modello a oggetti sotto di esso.

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.
