</div>
<script>
var speedia=1
imga3.innerHTML=imga2.innerHTML
function Marqueeia(){
if(imga3.offsetTop-imga1.scrollTop <=0)
imga1.scrollTop-=imga2.offsetHeight
else{
imga1.scrollTop++
//这里是我自己写入的代码
if((imga1.scrollTop-1)%100==0){clearInterval(MyMaria);
window.setTimeout(function() {MyMaria=setInterval(Marqueeia,speedia)},1000)}
//结束
}
}
var MyMaria=setInterval(Marqueeia,speedia)
imga1.onmouseover=function() {clearInterval(MyMaria)}
imga1.onmouseout=function() {MyMaria=setInterval(Marqueeia,speedia)}
</script>
基本上是正常的，但是就是鼠标移到图片上后，在移出，重复来回移几次就不正常了。
------解决方案--------------------
用个比较笨的办法改的：
<script>
var speedia=10
var flag=1
imga3.innerHTML=imga2.innerHTML
function Marqueeia(){
if(imga3.offsetTop-imga1.scrollTop <=0)
imga1.scrollTop-=imga2.offsetHeight
else{
imga1.scrollTop++
//这里是我自己写入的代码
if((imga1.scrollTop-1)%100==0){clearInterval(MyMaria);
flag=0
window.setTimeout(function() {flag=1;MyMaria=setInterval(Marqueeia,speedia)},1000)}
//结束
}
}
var MyMaria=setInterval(Marqueeia,speedia)
imga1.onmouseover=function() {clearInterval(MyMaria)}
imga1.onmouseout=function() {if(flag){MyMaria=setInterval(Marqueeia,speedia)}}
