javascript问题....等等高手的出现~~~

Question

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)}} 
</script>

Answer 1

slowhand ，不能用啊，出错了

Answer 2

代码逻辑有问题，修改代码如下：<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<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>
