To gain more experience using event handlers in JavaScript, try the following exercises:
Add several additional links to the document in Listing 10.2. Include event handlers that display a unique description for each link.
Modify Listing 10.2 to display a default welcome message in the status line whenever a description isn't being displayed. (Hint: You'll need to include a statement to display the welcome message when the page loads. You'll also need to change the clearstatus function to restore the welcome message.)
