Lab 5—Your First JavaScripts

Part 2—Print array to screen using a for loop

In this script, you will simplify the body script using a for loop. During each loop, one book title will print to the screen.

 

1. If arrays.html is not already open, open it in NotePad++.
2. Save the file as arrays_for_loop.html.
3. Change the title of your page to "Array Script with For Loop by " and your name; for example, "Array Script with For Loop by Joy."
   
4. Change the body script, to read as follows:
   

   document.write('<ol>');
   for (var i=0; i<books.length; i++)
   {
       document.write('<li>'+books[i]+'</li>');
   }
   document.write('</ol>');

   
   
5. Save arrays_for_loop.html again.
6. In Firefox, open arrays_for_loop.html. Do all seven books print to the screen? If not, use the Firefox Error Console to find and fix and errors.
