jQuery驗證密碼強度的大寫和小寫

Question

$.validator.addMethod("validpassword", function(value, element) { 
    return this.optional(element) || 
     /^.*(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[\d])(?=.*[\W]).*$/i.test(value); 
}, "The password must contain a minimum of one lower case character," + 
      " one upper case character, one digit and one special character.."); 

上述正則表達式不大寫和小寫之間進行區分。怎麼了？

Answer 1

刪除i標誌。它使RegEx 不區分大小寫。此外，將[\W]延伸至[\W_]。

/^.*(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[\d])(?=.*[\W]).*$/i.test(value); 
//           Remove this ^

// Ok: 
/^.*(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[\d])(?=.*[\W_]).*$/.test(value);
