Name

DOMImplementation — methods independent of any particular document

Availability

DOM Level 1 Core

Also Implements

DOMImplementationCSS, HTMLDOMImplementation

If a DOM implementation supports the HTML and CSS modules, the DOMImplementation object also implements the DOMImplementationCSS and HTMLDOMImplementation interfaces. For convenience, the methods of these trivial interfaces are listed here along with the core DOMImplementation methods.

Methods

createCSSStyleSheet( ) [DOM Level 2 CSS]

This DOMImplementationCSS method creates a new CSSStyleSheet object.

createDocument( ) [DOM Level 2]

Creates a new Document object with a root element (the documentElement property of the returned Document object) of the specified type.

createDocumentType( ) [DOM Level 2]

Creates a new DocumentType node.

createHTMLDocument( ) [DOM Level 2 HTML]

This HTMLDOMImplementation method creates a new HTMLDocument object and populates it with <html>, <head>, <title>, and <body> elements.

hasFeature( )

Checks whether the current implementation supports a specified version of a named feature.

Description

The DOMImplementation interface and its HTMLDOMImplementation and DOMImplementationCSS subinterfaces are placeholders for methods that are not specific to any particular Document object but rather are “global” to an implementation of the DOM. You can obtain a reference to the DOMImplementation object through the implementation property of any Document object.
