JavaScript: how to return false to link without breaking function?

I have a question (surprisingly ;) ):

How can I return false to a link without breaking the function? I did this previously without jQuery, back then I set an animation to execute after an interval and returned false. This time I need the function to continue running.

function initNavLinks(){
    navLinks = $("div#header a").click(function(){
        return false;
        processSlideReq();
    })
}

Thanx in advance

Just as a theoretical curiosity, you could also use JavaScript 1.7's generator support (though it only works in Firefox and wouldn't apply for links).

function x() {
    yield false;
    yield doSomething();
}

first_return_value = x();
second_return_value = x();

You probably should just prevent the event's default action like this:

function initNavLinks(){
    navLinks = $("div#header a").click(function(e){
        e.preventDefault();
        processSlideReq();
    })
}

You may want to read jQuery's Event Object documentation and bind documention to understand the differences between of returning false, calling preventDefault() and calling stopPropogation() within event handlers.

Is there any reason why you can't just swap the lines around and do:

function initNavLinks(){
    navLinks = $("div#header a").click(function(){
        processSlideReq();
        return false;
    })
}

?
