Listings 19.11 and 19.12 - A modular news page - Tasks 1 to 4
- Create a showItems function that displays a specified number of news items on the page.
- Add a drop-down list to the page so the reader can choose the number of items to display.
- Create an update function that reads the number of items to display from the drop-down list and then calls showItems with the specified number.
- Add a 'show' button that calls the update function when clicked.
