Document

The Document interface represents any web page loaded in the browser and serves as an entry point into the web page's content, which is the DOM tree. The DOM tree includes elements such as <body> (en-US) and <table>, among many others. It provides functionality globally to the document, like how to obtain the page's URL and create new elements in the document.

The Document interface describes the common properties and methods for any kind of document. Depending on the document's type (e.g. HTML, XML, SVG, …), a larger API is available: HTML documents, served with the "text/html" content type, also implement the HTMLDocument (en-US) interface, whereas XML and SVG documents implement the XMLDocument (en-US) interface.

Non-standard extensions This API has not been standardized.

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Firefox notes

Mozilla defines a set of non-standard properties made only for XUL content:

document.currentScript (en-US) This API has not been standardized.
Returns the <script> (en-US) element that is currently executing.
document.documentURIObject (en-US)
(Mozilla add-ons only!) Returns the nsIURI object representing the URI of the document. This property only has special meaning in privileged JavaScript code (with UniversalXPConnect privileges).
document.popupNode (en-US)
Returns the node upon which a popup was invoked.
document.tooltipNode (en-US)
Returns the node which is the target of the current tooltip.

Mozilla also define some non-standard methods:

document.execCommandShowHelp Obsolete since Gecko 14.0
This method never did anything and always threw an exception, so it was removed in Gecko 14.0 (Firefox 14.0 / Thunderbird 14.0 / SeaMonkey 2.11).
document.getBoxObjectFor (en-US) This is an obsolete API and is no longer guaranteed to work.
Use the Element.getBoundingClientRect() (en-US) method instead.
document.loadOverlay
Loads a XUL overlay dynamically. This only works in XUL documents.
document.queryCommandText Obsolete since Gecko 14.0
This method never did anything but throw an exception, and was removed in Gecko 14.0 (Firefox 14.0 / Thunderbird 14.0 / SeaMonkey 2.11).

Internet Explorer notes

Microsoft defines some non-standard properties:

document.fileSize* This API has not been standardized. This is an obsolete API and is no longer guaranteed to work.
Returns size in bytes of the document. Starting with Internet Explorer 11, that property is no longer supported. See MSDN.

Internet Explorer does not support all methods from the Node interface in the Document interface:

document.contains
