什么是DOM？
"The W3C Document Object Model (DOM) is a platform and language neutral interface that allows programs and s cripts to dynamically access and update the content, structure, and style of a document."
“W3C文档对象模型（DOM）是一个能够让程序和脚本动态访问和更新文档内容、结构和样式的语言平台”
The W3C DOM provides a standard set of objects for representing HTML and XML documents, and a standard interface for accessing and manipulating them.

The DOM is separated into different parts (Core, XML, and HTML) and different levels (DOM Level 1/2/3):
DOM被分为不同的部分（核心，XML和HTML）和不同的版本（DOM 1/2/3）
