AJAX Tricks and Prototype

Event

Provides cross-browser compatibility.
We saw how to call observe and stopObserving. They are part of the Event package.
Register events:
$('firstline').observe('click', function () {alert('xpos=' + event.pointerX)})
Once you have an event you can ask: isLeftClick, pointerX, pointerY.
