JQuery :: Slide Effect - Different DIVs For Each Menu Item?

I want a menu at the top of the page. When I press a button in the menu the content of the page slides up, the content changes and it slides down. I've done this so far, but how can I do a more dynamic solution without having different divs for each menu item?

JS:
<script type="text/javascript" src="[URL]"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
$('#f1').click(function() {
a("1");
});
$('#f2').click(function() {
a("2");
});
$('#f3').click(function() {
a("3");
});
function a(info) {
$('#content').slideUp("normal");
document.getElementById('content').innerHTML = info;
$('#content').slideDown("normal");
};
});
</script>

HTML:
<div id="f1"><a href="#">Menu 1</a></div>
<div id="f2"><a href="#">Menu 2</a></div>
<div id="f3"><a href="#">Menu 3</a></div>
<div id="content">Chose something in the menu</div>
