[jQuery] Stopping a link from forwarding

[atomicnuke]

I have the following code and was wondering how you stop a link from
forwarding to the url when clicked? I'd assume it'd go inside the
click, but couldn't find a way looking through the Visual jQuery.

$("#pnav li a").click(function(){
        $("#article").slideUp("slow");
});

Also, not sure if anyone will get this message. This is the 3rd
response/post I've tried that has not appeared. I've waited to see if
they post, but never do.
