文档对象模型 (DOM) 是 HTML 和 XML 文档的编程接口。它给文档（结构树）提供了一个结构化的表述并且定义了一种方式—程序可以对结构树进行访问，以改变文档的结构，样式和内容。 DOM 提供了一种表述形式— 将文档作为一个结构化的节点组以及包含属性和方法的对象。从本质上说，它将 web 页面和脚本或编程语言连接起来了。
尽管通常会使用 JavaScript 来访问 DOM， 但它并不是 JavaScript 的一部分，它也可以被其他语言使用，
这里有一篇可用的 DOM 介绍 。

过时的 DOM 接口
The Document Object Model is in the process of being heavily simplified. In order to achieve this the following interfaces present in the different DOM level 3 or earlier specification have been removed. It is still unclear if some may be reintroduced, but for the moment they have to be considered as obsolete and should be avoided:
HTML 接口
A document containing HTML is described using the HTMLDocument interface. Note that the HTML specification also extends the Document interface.
An HTMLDocument object also gives access to browser features: the tab, or window, in which a page is drawn using the Window interface, the Style associated to it (usually CSS), the history of the browser relative to the context, History , eventually a Selection done on the document.

SVG 数据类型接口
Here are the DOM API for data types used in the definitions of SVG properties and attributes.
注意: Starting in Gecko 5.0,the following SVG-related DOM interfaces representing lists of objects are now indexable and can be accessed like arrays; in addition, they have a length property indicating the number of items in the lists: SVGLengthList, SVGNumberList, SVGPathSegList, and SVGPointList.
