<script type="text/javascript">
window.onload=function(){
var box=document.getElementById("box");
var list=document.getElementById("list");
var buttoms=document.getElementById("buttoms").getElementsByTagName("span");
var prev=document.getElementById("prev");
var next=document.getElementById("next");
}（将这个大括号移到</script>前面）
// function animate(offset){
// list.style.left=parseInt(list.style.left)+offset+"px";
// }
next.onclick=function(){
list.style.left=parseInt(list.style.left)-900+"px";
}
prev.onclick=function(){
list.style.left=parseInt(list.style.left)+900+"px";
}
</script>
