推荐答案

使用
验证密码 -必须为8个字符，包括1个大写字母，1个特殊字符&字母数字字符

Validating password with
-must be 8 characters including 1 uppercase letter, 1 special character & alphanumeric characters

(?=.*\d)        #   must contain at least one digit
(?=.*[A-Z])     #   must contain at least one uppercase character
(?=.*\W)        #   must contain at least one special symbol
   .            #   match anything with previous condition checking
{8,8}           #   length at least 8 characters and also maximum of 8

一行:

In one line:

((?=.*\d)(?=.*[A-Z])(?=.*\W).{8,8})
