In the context of Ajax actions, what defines the events for triggering Screen Actions?

In the context of Ajax actions within the OutSystems platform, the correct triggering of Screen Actions is determined by user interactions with the interface elements, which can include events like clicking a button or changing the value of an input field. Specifically, the events "On Click" or "On Change" are pivotal, as they instruct the system to execute a specific Screen Action when users interact with certain widgets on the application screen.

For example, a button might be set to trigger a Screen Action when a user clicks it, while a dropdown might trigger a different action when the user selects a new option. This user-driven interaction is essential for making web applications responsive and interactive, as well as for executing background processes without needing to reload the entire screen.

By recognizing that user interactions such as clicks and changes directly correlate with the triggering of Screen Actions in Ajax operations, developers can create seamless and dynamic user experiences. This is fundamental to the functionality of web applications and highlights the importance of user engagement in executing defined actions.
