[jQuery] Making a button in active

[jQuery] Making a button in active


Good Afternoon (or morning depending on where you are).
I really hate posting probably quite simple questions to forums, but
this is really foxing me.
    $(".btn").click(function(){
        //.btn is now NOT clickable
        $("#somethingElse").doStuff("slow", function(){
            //.btn is now clickable
        });
    }
I've got a long navigation, and pages slide in and out of view.
Troubles are, if the user impaitently clicks a load of links while the
page loading and sliding in is happening, it melts my (probably poorly
written) code.
So, I'm trying to stop the user from clicking on any other buttons,
while the page loader is doing it's thing.
