If a user is to be redirected to a new page upon clicking a button, what must be defined?

• A. Page parameters
• B. Event handler
• C. Style attributes
• D. Data bindings

Answer: (B)

When a user clicks a button and you want to redirect them to a new page, it is essential to define an event handler. An event handler is a piece of code that responds to an event, such as a button click. By implementing event handling, you can specify the action to take when the user interacts with the button, including directing them to a different page. In this context, the event handler can be programmed to trigger the redirection, ensuring that the user's action has the desired result of navigating to the specified new page. This is a fundamental component of interactivity within a user interface, as it allows the application to respond dynamically to user inputs. Other choices, while important in their own right, do not directly facilitate the redirection process. For instance, page parameters might be used to pass information between pages, style attributes are meant for defining the visual elements of the button, and data bindings are typically utilized to link UI components with data sources. None of these elements would inherently handle the click event required for page redirection.
