The Document Object Model, or DOM, is a W3C standard for accessing and manipulating elements of a document. It is covered largely by the specs listed at <
http://w3.org/dom/DOMTR> and is the most used set of JavaScript host objects. It specifies a standard for such things as the document element, the methods getElementById, getElementByTagName, createElement, createTextNode, the collections document.forms, document.images, document.links, and much, much more.
