Document.body

La proprietà Document.body rappresenta il nodo <body> o <frameset> del documento corrente, o null se non esiste alcun elemento di questo tipo.

Sintassi

var objRef = document.body;
document.body = objRef;

Esempio

// Dato questo HTML: <body id="oldBodyElement"></body>
alert(document.body.id); // "oldBodyElement"

var aNewBodyElement = document.createElement("body");

aNewBodyElement.id = "newBodyElement";
document.body = aNewBodyElement;
alert(document.body.id); // "newBodyElement"

Appunti

document.body è l'elemento che contiene il contenuto per il documento. Nei documenti con contenuto <body> restituisce l'elemento <body>, e nei documenti frameset, restituisce l'elemento <frameset> più esterno.

Anche se body è settabile, l'impostazione di un nuovo corpo su un documento rimuoverà efficacemente tutti i figli attuali dell'elemento <body>.
