html replacement characters

May 15, 2023 pm 04:09 PM

HTML (Hypertext Markup Language)是一种用于构建网页的标记语言。在HTML中,有许多特殊字符(例如小于号、大于号、引号等),这些字符被称为“保留字符”或“转义字符”。这些特殊字符可能会干扰你的HTML代码,因此有时需要将它们替换为它们的实体字符或代码。

我们来讲一讲如何在HTML中替换字符。

  1. 替换小于号和大于号

在HTML中,小于号和大于号“<”和“>”被用于标记标签的开始和结束。如果要在HTML中使用这些字符实体而不是标签,我们需要将它们替换为以下实体字符:

  • “<”替换为“<”
  • “>”替换为“>”

例如,如果你想在HTML中显示一个包含小于号和大于号的字符串,可以按照以下方式编写:

&lt;Hello&gt; World!
Copy after login

输出结果为:

<Hello> World!
Copy after login
  1. 替换单引号和双引号

在HTML中,单引号和双引号用于定义属性值。如果想在HTML中使用这些字符本身而不是属性值,我们需要将它们替换为以下实体字符:

  • 单引号“'”替换为“'”
  • 双引号“"”替换为“"”

例如,如果你想在HTML中显示一个包含单引号和双引号的字符串,可以按照以下方式编写:

She said, &quot;I&apos;m happy.&quot;
Copy after login

输出结果为:

She said, "I'm happy."
Copy after login
  1. 替换版权标志

在HTML中,版权标志用于表示文本、图片等的版权归属。如果想在HTML中使用版权标志符号“©”,我们需要将它们替换为以下实体字符:

  • 版权标志“©”替换为“©”

例如,如果你想在HTML中显示版权信息“Copyright © 2020 My Website”,可以按照以下方式编写:

Copyright &copy; 2020 My Website
Copy after login

输出结果为:

Copyright © 2020 My Website
Copy after login
  1. 替换其它特殊字符

在HTML中,还有一些其它特殊字符,例如注册商标符号、不断开空格符号等。如果要在HTML中使用这些特殊字符,我们需要将它们替换为以下实体字符:

  • 注册商标符号“®”替换为“®”
  • 不断开空格符号“ ”(第二个字符为不可见字符)替换为“ ”

例如,如果你想在HTML中使用注册商标符号“®”和不断开空格符号,在代码中需要这样写:

Trademark &reg; and a non-breaking space.
Copy after login

输出结果为:

Trademark ® and a non-breaking space.
Copy after login

需要注意的是,不要滥用特殊字符实体。在现代网站中,使用CSS样式和JavaScript功能可以很好地替代大多数特殊字符实体,这样可保持HTML代码整洁和易读。

总结

当在HTML中需要使用特殊字符时,使用字符实体是一种很好的方式。HTML字符实体使用简单,而且可以使代码更通用、更易于阅读和理解。谨记上述方法,就可以很好地掌握如何在HTML中替换特殊字符了!
