JavaScript更改class和id的方法 javascript弹出一个层并增加一个覆盖层

方便做一些问题提交等宣传效果，多用于文字滚动

复制代码代码如下:

<script type="text/javascript"> 
var scrollDelay=10;//数字越大速度越慢 
var Scroll=document.getElementById("scroll"); 
var Scroll2=document.getElementById("scroll2"); 
var currentTop=0,preTop=0,stoptime=0,stopscroll=false; 
var ScrollChild=Scroll.getElementsByTagName("li"); 
var ScrollHeight=Scroll.offsetHeight; 
function ScrollInfo(){ 
if(stopscroll==true) return; 
currentTop++; 
if(currentTop+1>=ScrollHeight){ 
currentTop--; 
stoptime++; 
if(stoptime==parseInt(ScrollHeight)*scrollDelay) { 
currentTop=0; 
stoptime=0; 
} 
}else{ 
preTop=Scroll.scrollTop; 
Scroll.scrollTop++; 
if(preTop==Scroll.scrollTop){ 
Scroll.scrollTop=Scroll2.offsetHeight-ScrollHeight; 
Scroll.scrollTop+=1; 
} 
} 
} 
function Int_Scroll(){ 
Scroll2.innerHTML=""; 
Scroll2.innerHTML=Scroll.innerHTML; 
Scroll.innerHTML=Scroll2.innerHTML+Scroll2.innerHTML; 
Scroll.onmouseover=function(){ 
stopscroll=true; 
} 
Scroll.onmouseout=function(){ 
stopscroll=false; 
} 
setInterval("ScrollInfo()",scrollDelay); 
} 
window.setTimeout("Int_Scroll()",1000); 
</script>

点击运行可以看到效果:
