    Unfortunately, it is not possible to change the property of a field when it is filled using JotForm builder. However, you may achieve this by downloading the full source code of the form and adding additional JavaScript code. When you get the source code to modify, you'll need to host the form on your webserver.

    Please refer to the link below that might help you in achieving this requirement. 


    An example with a textfield changing color when filled is shown below :


    Hope this information helps!
