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> and <table>, among many others. It provides functionality global 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 interface, wherease SVG documents implement the SVGDocument interface.
Properties
This interface also inherits from the Node and EventTarget interfaces.

id. This is a legacy, non-standard interface and you should use thedocument.getElementById()method instead. Document.async- Used with

Specifications
Browser compatibility notes
Firefox notes
Mozilla defines a set of non-standard properties made only for XUL content:
document.currentScript- Returns the
<script>element that is currently executing. document.documentURIObject- (Mozilla add-ons only!) Returns the
nsIURIobject representing the URI of the document. This property only has special meaning in privileged JavaScript code (with UniversalXPConnect privileges). document.popupNode- Returns the node upon which a popup was invoked.
document.tooltipNode- Returns the node which is the target of the current tooltip.
Mozilla also define some non-standard methods:
document.execCommandShowHelpObsolete 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- Use the
Element.getBoundingClientRect()method instead. document.loadOverlay- Loads a XUL overlay dynamically. This only works in XUL documents.
document.queryCommandTextObsolete 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*- 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
Nodeinterface in theDocumentinterface:
document.contains- As a work-around,
document.body.contains()can be used.
