大功告成.试试这个:

/^[a-zA-Z0-9 .!?"-]+$/

请注意，- 字符的位置很重要.如果它出现在两个字符之间(例如 a-z)，则表示一个字符范围.如果它出现在字符类的开头或结尾(或者如果它被转义)，它代表一个文字连字符.

Note that the position of the - character is important. If it appears between two characters (e.g. a-z) it represents a character range. If it appears in at the beginning or end of the character class (or if it's escaped) it represents a literal hyphen character.
