类似于按F3的功能～！
只搜索当前页中是文字～！
不要查询数据库

Find next occurance of the given string on the page, wrap around to the
start of the page if necessary.

Look for match starting at the current point. If not found, rewind
back to the first match.

Find the nth match from the top of the page.

HTML (Hypertext Markup Language) 是一种用于创建网页的标准语言。它使用标记标签来描述网页的结构和内容。浏览器解析 HTML 代码并将其显示为网页。HTML 标签是由尖括号包围的关键字，如 <html>和 </html>。标签通常成对出现，用于定义元素的开始和结束。例如 <p>表示段落的开始， </p>表示段落的结束。
HTML 文档由一系列标签组成，每个标签都定义了文档的不同部分。例如 <head>标签定义了文档的头部，<body>标签定义了文档的正文。
HTML 的最新版本为 HTML5，它增加了许多新标签和特性，比如支持多媒体元素，更好的表单处理和更强大的本地存储功能。
