Assignment #5: Repetition (Arrays and Loops)

• Create a Web page which contains a questionnaire that prompts the user for personal information such as name, address, occupation, etc.
  
  
• Use at least three prompts (meaning, get at least three pieces of information from the user).
  
  
• This questionnaire, using the prompts, is a very inefficient way to get your visitor's information. An HTML input form would be much better. We'll see how to use a form to get this kind of information into JavaScript variables in several weeks.
  
  
• Create an array to hold the pieces of information that you get from the user. Assign each piece of information (from each of the prompts that you use) to its own separate element in the array.
  
  
• Use a for loop to display the information that you got from the user (and stored in the array) in the document's body. Your page should look something like this (after the prompts are all done):

        Thank you for your information!  You supplied this information:
        
        Jim Link
        123 Main St.
        Web Programmer
        

  (But only the information that you got from the prompts, not the heading, should be displayed with your for loop. The heading in this sample display is the part that says "Thank you for your information! You supplied this information:")
  
  
• Save the file as Questionnaire.html.
  
  
• Hints:
  • Use a prompt( ) statement for each piece of information that you ask the visitor for. You can code the prompt statements one after the other to get all of the information that you need.
  • Recall that the length property of an array tells you how many items (elements) are in the array.
  • Also recall that a for loop on an array normally tests for the counter being less than the length property of the array.
  
  
• Add a hypertext link to the index.html file that is in your class folder. Make this hypertext link display the html page that you made for this assignment.
  
  
• Validate your page using the W3C HTML Validator. (The Validator will automatically detect whether you have an XHTML or an HTML5 document.)
  
  
• Test your pages to make sure they have no errors in them. (You should turn on the display of script errors in your browser!) Here are some instructions on how to turn on JavaScript error messages.
  
  
• Upload your files to your class folder. You will need to use an FTP program to upload the files. You will find some general FTP instructions on a page called "FTP Instructions".
