Regular Expression for user name, password, mobile phone number, ID card (recommended), regular expression for mobile phone number

Regular Expression for user name, password, mobile phone number, ID card (recommended), regular expression for mobile phone number

I will not talk much about it. I will introduce you to using regular expressions to verify your username, password, mobile phone number, and ID card. For more information, see.
