Returns the <body> or <frameset> node of the current document, or null if no such element exists.

Syntax

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

Example

// in 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"

Notes

document.body is the element that contains the content for the document. In documents with <body> contents, returns the <body> element, and in frameset documents, this returns the outermost <frameset> element.

Though body is settable, setting a new body on a document will effectively remove all the current children of the existing <body> element.

  1. Although document.body is a perfectly acceptable way to select the <body> element in HTML, it's not implemented in Firefox if Content-Type is not set to text/html or application/xhtml+xml. A much safer way of selecting the <body> element is to use document.getElementsByTagName("body"), which should return an array with a single item. This is portable across HTML and XHTML where the Content-Type is not set within the HTTP response header.
