How to prevent users from copy & paste data in form fields?

I would like to use this link for an exam although as it is online copy and pasting is considered a violation of the exam condition.

Hello Sienna,

I am not sure if I have understood your question correctly. Do you mean to say that you want to prevent users from copy pasting data in textbox of your form?

Unfortunately it is currently not possible to detect and prevent copy & paste of data. The only possibility is to download your form's full source code and add custom code to prevent copy & paste of data in textboxes. You may like to take a look at the following thread where one of my colleague have shared the code to achieve this:  https://www.jotform.com/answers/37911
