class js.html.Document extends Node
Available on js
Each web page loaded in the browser has its own document object. This object serves as an entry point to the web page's content (the DOM tree, including elements such as <body>
and <table>
) and provides functionality global to the document (such as obtaining the page's URL and creating new elements in the document).
A document object can be obtained from various APIs:
- Most commonly, you work with the document the script is running in by using
document
in document's scripts. (The same document can also be referred to aswindow.document
.) - The document of an iframe via the iframe's
contentDocument
property. - The
responseXML
of anXMLHttpRequest
object. - The document, that given node or element belongs to, can be retrieved using the node's
ownerDocument
property. - ...and more.
Depending on the kind of the document (e.g. HTML or XML) different APIs may be available on the document object. This theoretical availability of APIs is usually described in terms of implementing interfaces defined in the relevant W3C DOM specifications:
- All document objects implement the DOM Core
Document
andNode
interfaces, meaning that the "core" properties and methods are available for all kinds of documents. - In addition to the generalized DOM Core document interface, HTML documents also implement the
HTMLDocument
interface, which is a more specialized interface for dealing with HTML documents (e.g., document.cookie, document.alinkColor). - XUL documents (available to Mozilla add-on and application developers) implement their own additions to the core Document functionality.
Methods or properties listed here that are part of a more specialized interface have an asterisk (*) next to them and have additional information in the Availability column.
Note that some APIs listed below are not available in all browsers for various reasons:
- Obsolete: on its way of being removed from supporting browsers.
- Non-standard: either an experimental feature not (yet?) agreed upon by all vendors, or a feature targeted specifically at the code running in a specific browser (e.g. Mozilla has a few DOM APIs created for its add-ons and application development).
- Part of a completed or an emerging standard, but not (yet?) implemented in all browsers or implemented in the newest versions of the browsers.
Detailed browser compatibility tables are located at the pages describing each property or method.

Instance Fields
Returns a semicolon-separated list of the cookies for that document or sets a single cookie. Getter throws DOMException. Setter throws DOMException.
var designMode:String
Gets/sets WYSYWIG editing capability of Midas. It can only be used for HTML documents.
Returns the Element that is a direct child of document. For HTML documents, this is normally the HTML element.
var implementation:DOMImplementation
Returns the DOM implementation associated with the current document.
var onreadystatechange:EventListener
- Returns the event handling code for the
readystatechange
event.
Starting in Gecko 9.0 (Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6)
, you can now use the syntax if ("onabort" in document)
to determine whether or not a given event handler property exists. This is because event handler interfaces have been updated to be proper web IDL interfaces. See DOM event handlers for details.
var xmlEncoding:String
Returns the encoding as determined by the XML declaration.
var xmlStandalone:Bool
Returns true
if the XML declaration specifies the document is standalone (e.g., An external part of the DTD affects the document's content), else false
. Setter throws DOMException.
var xmlVersion:String
Returns the version number as specified in the XML declaration or "1.0"
if the declaration is absent. Setter throws DOMException.
