為什么我的毫無反應呢？？半天都沒找出來。

你好，其實只是一些小問題，
<script type="text/avascript">是javascript，這個應該影響不大，
aLi.time=null;aLi[i].timer=null;//應該是點的哪一個
function startMove(obj,terget){
clearInterval(obj.timer);
obj.timer=setInterval(function(){
var speed=(terget-obj.offsetWidth)/8;
speed=speed>0?Math.ceil(speed):Math.floor(speed);
if(obj.offsetWidth==terget){clearInterval(obj.timer);}?
else{obj.style.width=obj.offsetWidth+speed+"px";
},30)? //掉了一個'}'，這是主要的
