Overview

You will study and create Web pages that conditionally respond to user input and events as well as count events. This is an individual assignment.

Requirements

Create a Web page for each of the following exercises:

1. Study the Weather page. Answer the following questions on a Web page:
1. Trace the code for a temperature of 10 and a humidity of "Dry". Explain what happens in the code. Make sure you present function calls, variable assignments and tested conditions.
2. Trace the code for a temperature of 50 and a humidity of "Wet". Explain what happens in the code. Make sure you present function calls, variable assignments and tested conditions.
3. What happens if the Temperature text box is left blank? Why?
4. How does the function getDesc obtain the temperature and humidity values? Does it have any parameters? Explain.
5. What does the function getDesc do with the weather description? Does it use a return statement? Explain.
2. On a separate page, modify the weather page so that it presents weather descriptions that better fit your sensibilities (I'm guessing that you wouldn't consider a picnic if it's 45 degrees and raining). Your new page should provide at least six different weather descriptions.
3. Study the Dice 2 page. This is a modified version of the dice page presented in chapter 11. Using a few sentences, explain what happens when the button is pushed. Make sure you present function calls, variable assignments, string concatenations and image presentations.
4. Modify the dice 2 page so that it has the following qualities (you are strongly encouraged to take an incremental approach):
• Have your program count the number of dice rolls. Create a new text box and display the number of dice rolls in the text box. In addition to class notes, you may want to read about Counters on pp. 206-208 in the Reed text.
• Have your program count the number of doubles. Create a new text box and display the number of doubles in the text box.
• Customize the presentation of your dice page with headers and additional formatting.

Optional challenge: add a reset button to your dice page so that counts are reset to zero when the reset button is pushed.

Once you have completed the Web pages above, create a navigation page that provides links to the exercise pages. Format this page using a suitable list. Add your name to this page.
