为什么代码不运行？

Question

window.onload = function(){

var aLi = document.getElementsByTagName("li");

   for (var i=0;i<aLi.length;i++){

 aLi[i].onmouseover = function(){

startMove(this,400);

}

 aLi[i].onmouseout = function(){

startMove(this,200);

}

}

}

var timer = null;

function startMove(obj,iTarget){

var aLi = document.getElementsByTagName("li");

timer=setInterval(function(){

clearInterval(timer);

var speed = (iTarget - obj.offsetWidth)/10;

speed = speed>0?Math.ceil(speed):Math.floor(speed);

if(obj.offsetWidth = iTarget){

clearInterval(timer);

}

else{

obj.style.width = obj.offsetWidth + speed + 'px';

}

 },30)

}

Answer 3

代码输入有误，多了：“ },30)”
