基于jQuery实现的单行公告活动轮播效果

废话不多说了，直接给大家贴代码了，具体代码如下所示：

<div class="lunbo123" style="position:relative;height: 45px;overflow: hidden;background-color:white" ;>
<ul id="myul" style="margin:6px;padding:0px;position:absolute;width: 700px; height: auto;">
<li>
<a href="" style=" rel="external nofollow" rel="external nofollow" text-decoration: none;color: #000000; ">
<span style="height:36px ; line-height: 36px;">公告test1 
</span>
</a>
</br>
</li>
<li>
<a href="" style=" rel="external nofollow" rel="external nofollow" text-decoration: none;color: #000000; ">
<span style="height:36px ; line-height: 36px;">活动test2 
</span>
</a>
</br>
</li>
</ul>
</div>
<script src="//cdn.bootcss.com/jquery/2.2.2/jquery.js"></script>
<script>
function lunbo123(id, height) {
var ul = $(id);
var liFirst = ul.find('li:first');
$(id).animate({
top: height
}).animate({
"top": 0
}, 0, function() {
var clone = liFirst.clone();
$(id).append(clone);
liFirst.remove();
})
}
setInterval("lunbo123('#myul','-45px')", 2500)
</script>
<style>
#myul {
list-style-type: none;
width: 300px;
height: 45px;
font-size: 20px;
}
</style>
