Lecture Examples

I added some comments to the class example (see the script.js and jspage.html files). I'll be talking more about JavaScript and closures on Wednesday. Next week we will cover DOM manipulation and jQuery.

The example files show a simple way to handle events. However, the recommended way is to use a JavaScript library. Different browsers implement event-handling in different ways (they are converging, but there are a lot of old browsers in use) and there are many good javascript libraries that deal with all this ugliness so we don't have to. We will be using jQuery.

We will be building again on our surveys webapp in future weeks: adding some drag-and-drop editing and AJAX functionality, and graphics, gotta have graphics! Stay tuned.
