I am having some problem understanding an event in jquery.
Given the following example http://api.jquery.com/event.pageY/, I don't quite understand what 'e' is and what it does. The rest of the code is kinda clear, it basically gets the coordinates but I don't understand what is the function of 'e' and where it comes from because it doesn't seem to have been declared anywhere, so it is a parameter holding what?
Any simple suggestion?!
