这段JAVA语言怎么改才符合W3C标准呀

哪位高手能把以下代码
改成符合W32标准的?感激不尽
FIREFOX的 JAVASCRIPT控制台提示最后三行"ID/NAME所引用的元素位于全局范围，请使用W32的标准形式document.getelementbyid()
"

<SCRIPT language=JavaScript>
marqueesWidth=780;
with(marquees){
style.height=0;
style.width=marqueesWidth;
style.overflowX="hidden";
style.overflowY="visible";
noWrap=true;
onmouseover=new Function("stopscroll=true");
onmouseout=new Function("stopscroll=false");
}
preLeft=0; currentLeft=0; stopscroll=false;
function init(){
templayer.innerHTML="";
templayer.innerHTML+=marquees.innerHTML;
marquees.innerHTML+=templayer.innerHTML;
setInterval("scrollLeft()",30);
}init();
function scrollLeft(){
if(stopscroll==true) return;
preLeft=marquees.scrollLeft;
marquees.scrollLeft+=1;
if(preLeft==marquees.scrollLeft){marquees.scrollLeft=templayer.offsetWidth-marqueesWidth+1;
}
}
