Digital Media Projects Office | Hands On Internet Series

Welcome to the Digital Media Project Office's
JavaScript pages

These pages are used to demonstrate some of the things you can do with JavaScript and are used as the basis for courses taught to Ryerson faculty and staff by the Digital Media Projects office and to students in the Rogers Centre's Hands On Internet series.

To use this site you must have Netscape 3 or later. Actually, its a good idea right now (Nov. 97) to test scripts with Netscape 3.03 and Communicator 4.02, and 4.04 as Communicator introduced some new bugs that Netscape 3 didn't have. Some of these, such as problems with image object onload events were resolved by at least 4.04. But Netscape Communicator also introduced significant new features that may break scripts that worked fine in Navigator 3.

Here is a list of what is available on this site:

1. Lecture Notes at http://www.ryerson.ca/JavaScript/lectures These notes are delivered with a Frameset and JavaScript Lecture viewer.
2. Lecutre Notes at http://www.ryerson.ca/JavaScript/lectures.html The same lecture notes but launched through a separate window that you configure using a form.
3. Form Events Demonstration. http://www.ryerson.ca/JavaScript/Events/evframe.html
4. JavaScript Quiz. A little tutorial tool using JavaScript.
5. Play hangman! A demonstration of how JavaScript can make images, frames, and form elements more interactive. Just press start after the frames load.

• A particularly creative use of JavaScript can be found at http://www.hidaho.com/c3. This is a colour tester written entirely in JavaScript that allows you to try different colours for text, backgrounds, and links in an HTML document. The same site (http://www.hidaho.com) also has documentation and the code for a set of JavaScript functions that provide global function registration, a function calling mechanism across frames, and synchronization of functions.
• Gordon McComb wrote a book for John Wiley & Sons, Inc. called the JavaScript Sourcebook. He has posted examples from the book at: http://gmccomb.ocm/javascript.
• Andy Augustine maintains a JavaScript FAQ at http://www.freqgrafx.com/411 along with other JavaScript information. If something doesn't work, and you can't make it work, you should check the JavaScript FAQ.
