Open the HTML and JavaScript files provided as start up files (index.html and navigation.js). Then, run the application and notice that when you click on a link in the sidebar, the page is scrolled so the information for the speaker associated with that link is displayed. In other words, this application works even if JavaScript is disabled. In the JavaScript file, add an event handler for the ready event method. Then, within the function for that event handler, add jQuery code that hides the heading and article for all but the first speaker. Add an event handler for the click event of the <a> elements in the sidebar. Then, within the function for that event handler, add jQuery code that hides all the speaker information, gets the value of the href attribute of the link that was clicked, and then uses that value to display the heading and article for the speaker associated with that link.
