jQuery - Several functions on one element

Im currently developing a wordpress site for a client, and they want to have a scroller which disapears from the click of a button and then shows content in a modal window blah blah blah ... It seems to all work, except when i put it all together when i click on a li element, it just displays the link in the address bar and doesnt go anywhere ... i have a feeling its got to do with disabling the normal function of a href but i wasnt sure how to get around it.

So for the scroller i have the following structure

<div class="scrollerone">
    <ul>
        <li><a href=""><img src="image.jpg" /></a></li>
        <li><a href=""><img src="image.jpg" /></a></li>
        <li><a href=""><img src="image.jpg" /></a></li>
        <li><a href=""><img src="image.jpg" /></a></li>
        <li><a href=""><img src="image.jpg" />&开发者_如何学运维lt;/a></li>
        <li><a href=""><img src="image.jpg" /></a></li>
        <li><a href=""><img src="image.jpg" /></a></li>
    </ul>
</div>

The jQuery code i have is as follows ....

<script type="text/javascript">
    jQuery(function() {
        jQuery(".scrollerone").jCarouselLite({
            btnNext: "#btnnext1",
            btnPrev: "#btnprev1"
        });
    });
</script>

<script type="text/javascript">
    jQuery(function(){
        var list = jQuery('.scrollerone');
        var original_height = list.height();
        var new_height = '0';
        list.css({height:new_height});

        jQuery('#refl').click(function() {

            if(list.height() == original_height){
                jQuery('.viewcs').html('VIEW ALL CASE STUDIES');                                    
                list.animate({height:new_height});
            } else {
                list.animate({height:original_height});
                jQuery('.viewcs').html('CLOSE ALL CASE STUDIES');
            }
            return false;
        });
    });
</script>

If anyone could shed some light on this, that would be great ... I have a feeling that the return false bit disables the usual click behaviour, but it shouldnt affect the clicking on the li elements in the scroller should it?

Cheers,

$("a").click(function(event) {
  event.preventDefault();

});

use event.preventDefault to stop the default event of the anchor..
