HTML 字符实体对照表

简介

HTML 中一些字符在拥有特殊比如小于号 (<) 用于定义 HTML 标签的开始,如果我们希望浏览器正确地显示这些字符,我们必须在 HTML 源码中插入字符实体,否则会被当成标签来解析得到错误的结果;字符实体又两种表示方法:

  • & 加上实体名称后面再加分号,例如 小于号(<) 写成 &lt;
  • &# 加上十进制数字实体编号, &#x 加上十六进制数字实体编号,后面再加分号,例如 小于号(<) 写成 &#60; 或者 &#x3c;

大多数字符实体都可以在不进行实体引用的情况下使用,那些不容易通过键盘键入的符号就必须通过实体表达,如版权信息和商标等。

对照表

实体名称不是所有实体都有,实体编号和字符所在的编码一致,例如大写字母 A 编码的十进制是 65,所以 A 可以通过 &#65;表示

注意

  • 实体名称好处是容易记忆,但是不是所有的浏览器都支持最新的实体名称,对实体编号支持得反而更好,所以建议使用实体编号方式;另外实体对大小写敏感,使用时候要加以区分。
  • HTML 会裁掉文档中的空格,如果使用空格请使用实体 &nbsp;
