Hi, I have designed a sign up form with name, password, confirm password, and e-mail id text boxes. i am doing client side validation using angular js. Name, E-mail and PAssowrd test box perform the function as expected and i am able to do client side validtion through angular js. But in the confirm password field when i enter a wrong password angular js fails to validate it. I do not know what went wrong with my code. I tried googling out solution but did not get proper answer for this. Kindly help me in this. Many thanks in advance. here is my code

This is nothing but code dump, no problem is explained.
But your problem is: why comparing passwords at all? Storing passwords any where and comparing them is way too unsafe and absolutely not needed for authentication. Besides, why working on client side? Are you using any server-side technology? If not, you cannot really have safe password-based authentication.

Creating a separate directive for this is not needed. There is already a build in Angular UI password validation tool .angular-ui/ui-validate · GitHub[^] With this you could do:

<input name="password" required ng-model="password">
<input name="confirm_password"
ui-validate=" '$value==password' "
ui-validate-watch=" 'password' ">
