var?area?=?document.getElementsByClassName('moocBox')
?var?con1?=?document.getElementsByClassName('con1');
?var?con2?=?document.getElementsByClassName('con2');
?con2[0].innerHTML?=?con1[0].innerHTML;
var?iliheight?=?24;
????area[0].scrollTop?=?0;
????function?scrollrun(){
????????area[0].scrollTop++;
????????if(area[0].scrollTop?/?iliheight?==?0)
????????{
????????????clearInterval(time);
????????}
????}
????var?time?=?setInterval("scrollrun()",50);看出問題來沒有？當(dāng)使用getElementsByClassName時取得是一個類數(shù)組，需要加索引來取值，你打開控制臺看一下，肯定是報錯的，歡迎采納
