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


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


// 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"


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] The body property was implemented on the HTMLDocument interface in Firefox for a long time, hence document.body would not return the <body> element  if the document's Content-Type was not set to text/html or application/xhtml+xml (or if it came from DOMParser.parseFromString without the text/html type being used). This has been fixed in Firefox 60.
