</script>这是一个完整的幻灯js代码 原生js写的 但是有个问题是鼠标每次移动到左右按钮上时就会抽风，乱动。 查遍百度不知如何解决，求指教！！！！！
解决方案
动画没清除
function startMover(el,itarget){
clearInterval(el.timer);
var odiv = el;
el.timer = setInterval(function(){
var speed = 0;
if(odiv.offsetLeft > itarget){
speed = -5;
}else{
speed = 5;
}
if(odiv.offsetLeft == itarget){
clearInterval( el.timer);
}else{
odiv.style.left = odiv.offsetLeft+speed+'px';
}
},20);
}改成这样
