Assignment 3: Scripts and Variables

  1. [3 pts] Create a page that uses only a Javascript script element in the body of the document to create the following content:
    • A toplevel heading
    • A paragraph containing one short sentence of text
    • A list with two items in it
    Concentrate on making your scripts readable/understandable (as well as correct).
  2. [3 pts] Create a page that asks the user for their name and their favorite color and displays them in the body of the page.
  3. [3 pts] Extend your previous script so that the favorite color is displayed in that color. You may assume that the color is one of the predefined CSS color names.
  4. [3 pts] Create a page that asks a user first for their name, then for their favorite color, and then for their phone number and displays the results as a table in the page.

Things to think about

  • In developing your pages/scripts, be sure you understand the following:
    • Visiting the page in a real browser (Firefox recommended; Chrome or Safari usually also ok) to test its execution.
    • How to be notified of errors during your script's execution.
    • The basic development cycle for programming:
      1. Design
      2. Write the code
      3. Run the code (load the page)
      4. Works properly? You're done!
      5. Otherwise rewrite (go to 2) and/or redesign (go to 1)
      6. Repeat until done
    The more you understand this now, the easier life will be as we start developing more complicated programs. Use your lab times effectively, especially if you are new to programming.
  • When writing a script that generates HTML (for example, with document.write), first think what the HTML should look like. That is, what would it be if you were writing a static page. Then get your script to produce that HTML using document.write. And then use variables (and perhaps also window.prompt) to get the dynamic parts into the HTML that you're adding to the document.
