正则表达式，字母数字，少数特殊字符，没有其他字符

First of all pardon me with my English grammar. Anyway, I am trying to create a regular expression which contains alpha numeric characters including spaces, comma, full stop, exclamation point and question mark, but other characters and symbols are not allowed.

Would this regular expression work?

'/[^a-zA-Z\s,!?]$'

Thank you so much for the help

try this one /^[a-zA-Z0-9\s\.,!?]*$/
