<script>
var t=setInterval(myfunc,1000)
var d=document.getElementById("div1")
function myfunc(){
var o=d.firstChild
d.removeChild(o)
d.appendChild(o)
}
d.onmouseover=function(){clearInterval(t)}
d.onmouseout=function(){t=setInterval(myfunc,1000)}
</script>

上面显示的是四行，如果只要1行，或者几行 改这里height:68px
只显示1行：
<div id="div1" style="width:300px;height:15px;overflow:hidden">
