求助滑塊運動問題?。。?！
下面這段代碼到底哪里錯了，為什么它不會停止，而是一直滑動，求解
window.onload=function(){
var check=document.getElementById("check");
? check.onmouseover=function(){
? startMove(1,0);}
? check.onmouseout=function(){
? startMove(1,-100);}
? }
? var time=null;
? function startMove(speed,target){
? ? var box=document.getElementById("box");
clearInterval(time);
time=setInterval(function(){
if(box.offsetLeft==target)
clearInterval(time);
else
box.style.left=box.offsetLeft+speed+"px";
},30);
? }?

if else 語句錯了,else后面沒加花括號.
