javascript - jquery验证密码强度大小写

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..");

上面的正则表达式不区分大写和小写。怎么了？

Answer 1

删除 i 标志。它使 RegEx 不区分大小写。此外，将 [\W] 扩展为 [\W_]。

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

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