Javascript closures (I think)

Question

I've got a piece of code I'm working with that was handed down to me by a previous developer. I am just trying to understand it better and not just use it naively. Here's the code:

slides.paginator.click(function (e) {
    e.preventDefault();
    interval.stop();
    switchSlide($(this).index());
    interval.start();
});

The part that I do not understand is the argument e that is being passed through this anonymous function. I have seen this before and I thought it had something to do with closures, but again, I am not sure. Can anyone give me a little insight into exactly how this parameter e works? I have seen it in other cases as well, such as with jQuery's AJAX methods.

Even pointing me in the right direction towards an article would be a great help. Thanks!

Answer 1

"e" comes from "event", check the jquery .click() docs http://api.jquery.com/click/

function(e){} replaces "handler(eventObject)"
