How can i off Form Validation in on Change method of textField?

Actions & Logic

Form validation has been implemented for the TextField.
The form validation process is triggered when the Sign In button is pressed.
(Question) I receive a validation error notice, but I want it to disappear when I re-enter valid data in the TextField. How can I achieve this?
