HTML 教程

有两种使用 标签的方式:

  1. 通过使用 href 属性 - 创建指向另一个文档的链接
  2. 通过使用 name 属性 - 创建文档内的书签

HTML href

  • "链接文本" 不必一定是文本。图片或其他 HTML 元素都可以成为链接
  • 实例解析

    <a href="http://www.cnblogs.com/renleimlj/">Visit my blog!</a>

    效果展示

    Visit my blog!

    HTML target

  • 使用 Target 属性,你可以定义被链接的文档在何处显示
  • 实例解析

    <html><body><a href="http://www.cnblogs.com/renleimlj/" target="_blank">Visit my blog!</a><p>如果把链接的 target 属性设置为 "_blank",该链接会在新窗口中打开。</p></body></html>

    效果展示

    Visit my blog!

    如果把链接的 target 属性设置为 "_blank",该链接会在新窗口中打开。

    HTML name

  • name 属性规定锚(anchor)的名称,可用来创建书签
  • 书签不会以任何特殊方式显示,它对读者是不可见的
  • 锚(显示在页面上的文本)
  • 锚的名称可以是任何你喜欢的名字
  • 可以使用 id 属性来替代 name 属性,命名锚同样有效
  • 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>

    效果展示

    基本的注意事项 - 有用的提示
    有用的提示

    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。
