    网页(HTML)中的特殊字符

    (1)一般来说,在HTML中,一个特殊字符有两种表达方式,一种称作数字参考,一种称作实体参考。

    所谓数字参考,就是用数字来表示文档中的特殊字符,通常由前缀“&#”,加上数值,再加上后缀“;”而组成,它可以采用如下两种方式。

    &#D; 其中D是一个十进制数值

    下面是一些特殊字符的数字参考示例:

    © 对应于特殊字符“©”

    ® 对应于特殊字符“®”

    所谓实体参考,实际上就是用有意义的名称来表示特殊字符,通常由前缀“&”,加上字符对应的名称,再加上后缀“;”而组成,其表达方式如下:

    &name; 其中name是一个用于表示字符的名称,它是区分大小写的

    例如,可以使用“©”来表示版权符号“©”,用“®”来表示注册商标符号“®”,很显然,这比数字要容易记忆得多。

    遗憾的是,不是所有的浏览器都能够正确认出采用实体参考方式的特殊字符,但是它们都能够识别出采用数字参考方式的特殊字符,如果可能,对于一些特别不常见的字符,应该使用数字参考方式。

    当然,对于那些常见的特殊字符,使用其实体参考方式是安全的,我们在实际应用中,只要记住这些常用特殊字符字符的实体参考就足够使用了。

    (2)ddd   :表示 1 到 3 位八进制数代表的字符( 1 到 3 位八进制数为其ASCII码值)
    比如 'A'的ASCII码值为 65,表示成八进制为 101 ,所以也可以用'101'表示 'A'。
    xhh :表示 1 到 2 为十六进制数代表的字符。同上。



    以下列出了其中的大部分(从网上搜集而来):
