difference between e.preventDefault() and event.preventDefault()?

Is there any difference between these two? Or is just one an abbreviation of the other?

Well, the only difference is the name of event object that is being passed into your listener. If you declare the listener like this:

a.click(function(e) {
});

Obviously the name of event variable is "e" and you should call e.preventDefault. In the second case:

a.click(function(event) {
});

the name of the event object is "event", so you're calling event.preventDefault()

e is just an abbreviation for event, it depends on how the argument is accepted

It's just a matter of variable naming. Some people's convention is naming their event variable e, ev, or event. Whichever best suits you.
