    I volontari di MDN non hanno ancora tradotto questo articolo in Italiano. Registrati per tradurlo tu.

    The DOMImplementation interface represent an object providing methods which are not dependent on any particular document. Such an object is returned by the Document.implementation property.

    Property

    This interface has no specific property and doesn't inherit any.

    Methods

    No inherited method.

    DOMImplementation.createDocument()
    Creates and returns an XMLDocument.
    DOMImplementation.createDocumentType()
    Creates and returns a DocumentType.
    DOMImplementation.createHTMLDocument()
    Creates and returns an HTML Document.
    DOMImplementation.hasFeature()
    Returns a Boolean indicating if a given feature is supported or not. This function is unreliable and kept for compatibility purpose alone: except for SVG-related queries, it always returns true. Old browsers are very inconsistent in their behavior.
