<h1>What is the Document Object Model?</h1>
<p>
The <abbr title="World Wide Web Consortium">W3C</abbr> defines the <abbr title="Document Object Model">DOM</abbr> as:
</p>
<blockquote cite="http://www.w3.org/DOM/">
<p>
A platform- and language-neutral interface that will allow programs and scripts to dynamically access and update the content, structure and style of documents.
</p>
</blockquote>
<p>
It is an <abbr title="Application Programming interface">API</abbr> that can be used to navigate <abbr title="HyperText Markup Language">HTML</abbr> and <abbr title="eXtensible Markup Language">XML</abbr> documents.

addLoadEvent函数写了吗？
另外，要发文本形式的代码，不要发图片。那样别人没法帮你调试代码
