密码验证不起作用

Question

https://secure.www.cartier.cn/zh-cn/服务/my-cartier/RegistrationStep1.html I am using below RegEx to validate my password using jQuery validation.

$.validator.addMethod("passwordTest", function(value, element) {
            return this.optional(element) || /^(?=.*\d)[0-9a-zA-Z\!\@\#\$\%\^\&\*\)\(\+\=\.\_\-\?\}\{\]\[\>\<\"\\\/\'\:\;]{8,}$/i.test(value);
        }, _objPropertiesMsg.passWeak);

Rules applied on password validation as mentioned in CARE-8804:

min 8 alphanumerical chars
combination of letters & numbers
no consecutive repeat of a char more than 2 times

It is working till 8 characters but above 8 characters all validations fails. Also it fails for 2 consecutive char check and accepting 8 only numbers.

I guess it is generally not a good idea, to try to check all your conditions in just one regex.

Instead, just check for length with pure javascript, have a regex checking for characters not occurring more than twice in a row and another one making sure that there is at least one digit followed by a non-digit or the other way around:

$.validator.addMethod("passwordTest", function(value, element) {
            return this.optional(element) || value.length>=8 && /^((.)\2?(?!\2))+$/i.test(value) && /(\d[^\d]|[^\d]\d)/.test(value);
        }, _objPropertiesMsg.passWeak);
