Hi All,
I write
JSP and
Servlet in order to register user and onkeyup I am calling my ajax code which is validating whether userID is already register or not. My problem is that ajax code always getting null value for valid tag value and because of that it's showing always valid user ID. Please find my code as follow:
1. register.jsp
2. FormValidation.java
3. validateUserId.js
Can anyone help me? I had mark ajax code in red color where I am getting error.
Thanking You,
