以下代碼jquery實現簡單的滾動，原理是克隆第一個li然后放到末尾，接著讓它往上滑動然后清除掉，反復循環
<script type="text/javascript">
function slide(ClassName){
var ID = setInterval ("run('"+ClassName+"')",1000);
$('.'+ClassName).mouseover(function(){
clearInterval(ID)
}).mouseout(function(){
ID = setInterval ("run('"+ClassName+"')",1000);
});
}
function run(ClassName){
$('.'+ClassName).find('li').first().clone().appendTo('.'+ClassName);
$('.'+ClassName).find('li').first().slideUp("slow",
function(){
$('.'+ClassName).find('li').first().remove();
}
);
}
$(function(){
slide('side-news-cnt');
});
</script>
