如何把這段代碼放到js文件里引用？
用window.onload會報錯。說是找不到area，
window.onload?=?function(){
var?area?=?document.getElementById('moocbox');
var?con1?=?document.getElementById('con1');
var?con2?=document.getElementById('con2');
con2.innerHTML?=?con1.innerHTML;
function?scrollUp(){
if(area.scrollTop?>=?con1.offsetHeight){
area.scrollTop?=?0;
}else{
area.scrollTop++;
}
}
var?timer?=?50;
var?myScroll?=?setInterval('scrollUp()',timer);
area.onmouseover?=?function(){
clearInterval(myScroll);
}
area.onmouseout?=?function(){
myScroll?=?setInterval('scrollUp()',timer);
}
}

js一般放在<head></head>之間或者單獨的js文件；
單獨的js文件引入：<script type="text/javascript" src="js文件目錄"></script>
