HTML name
实例解析
首先,我们在 HTML 文档中对锚进行命名(创建一个书签):
<a name="tips">基本的注意事项 - 有用的提示</a>
然后,我们在同一个文档中创建指向该锚的链接:
<a href="#tips">有用的提示</a>

基本的注意事项 - 有用的提示:
注释:请始终将正斜杠添加到子文件夹。假如这样书写链接:href="",就会向服务器产生两次 HTTP 请求。这是因为服务器会添加正斜杠到这个地址,然后创建一个新的请求,就像这样:"。
提示:命名锚经常用于在大型文档开始位置上创建目录。可以为每个章节赋予一个命名锚,然后把链接到这些锚的链接放到文档的上部。如果您经常访问百度百科,您会发现其中几乎每个词条都采用这样的导航方式。
提示:假如浏览器找不到已定义的命名锚,那么就会定位到文档的顶端。不会有错误发生。
