What is difference between action support and action function?..

Answer / Ram Avtar Sharma

Action Support in Visualforce provides a set of predefined behaviors for buttons, links, or input fields. Action functions are custom JavaScript functions that can be associated with those UI components to perform specific actions when triggered by the user. While Action Support offers basic functionality out-of-the-box, action functions offer greater flexibility and customization.
