In the DOM, the document object provides a general way to represent HTML, XHTML, and XML documents. Document objects implement the general DOM Core document interface (which itself implements the Node interface).

In addition to the generalized DOM Core document interface, HTML documents also implement the DOM HTMLDocument interface, which is a more specialized interface for dealing with HTML documents (e.g., document.cookie, document.alinkColor). Methods listed here that are part of this more specialized interface have an asterisk (*) next to them.

The document is contained by the window object and may contain any number of elements.

The document interface provides access to things such as the document type, its color and formatting, plugins and applets, as well providing methods for creating and manipulating all of the document's child nodes, or elements, such as BODY and TABLE elements.

Event handlers

Firefox 3 introduces two new events: "online" and "offline". These two events are fired on the <body> of each page when the browser switches between online and offline mode. Additionally, the events bubble up from document.body, to document, ending at window. Both events are non-cancelable (you can't prevent the user from coming online, or going offline). For more info see Online and offline events.

Security notes

Firefox 3 note

This section covers security improvements made in Firefox 3/Gecko 1.9.

When a new document is created, it initially gets "about:blank" loaded into it. In versions of Firefox prior to Firefox 3, "about:blank" documents didn't get the parent principle. This means that access to their contents was not restricted. While this doesn't seem like a significant issue, it can be if code proceeds to add content to the document using DOM methods and properties such as appendChild() and so forth, because that content would not be protected from unauthorized access.

Firefox 3 updates Gecko so that new documents inherit the parent principle. This improves security both for iframes and documents that are in the process of being loaded, as well as for documents constructed programmatically.
