5.3Develop and test an HTML document that has checkboxes for apple (59 cents each), orange (49 cents each), and banana (39 cents each), along with a Submit button. Each of the checkboxes should have its own onclick event handler. These handlers must add the cost of their fruit to a total cost. An event handler for the Submit button must produce an alert window with the message Your total cost is $xxx, where xxx is the total cost of the chosen fruit, including 5 percent sales tax. This handler must return false (to avoid actual submission of the form data). . 5.4 Develop and test an HTML document that is similar to that of Exercise 5.3. In this case, use text boxes rather than checkboxes. These textboxes take a number, which is the purchased number of the particular fruit. The rest of the document should behave exactly like that of Exercise 5.3.
