jQuery验证密码强度的大写和小写

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.."); 

上述正则表达式不大写和小写之间进行区分。怎么了？

Answer 1

删除i标志。它使RegEx 不区分大小写。此外，将[\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);
