用js写了一个菜单特效，其中的setTimeout为什么没起作用？
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>动画菜单</title>
<style type="text/css">
*{
margin: 0;
padding: 0;
}
ul {
list-style: none;
}
.nav{
width: 800px;
height: 60px;
margin: 50px auto;
}
.nav li {
float: left;
background: #ad3456;
height: 60px;
position: relative;
}
.nav li a {
line-height: 60px;
font-size: 16px;
color: #fff;
font-weight: normal;
text-align: center;
text-decoration: none;
display: block;
width: 90px;
}
.nav li a:hover {
background: #bb8888;
color: #ff5555;
}
#sub {
position: absolute;
left: 0;
top: 60px;
display: block;
height: 0;
overflow: hidden;
}
#sub li {
float: none;
}
</style>
<script type="text/javascript">
window.onload = function() {
var oli = document.getElementsByTagName('li');
for(var i = 0, length1 = oli.length; i < length1; i++){
oli[i].onmouseover = function () {
var ul = this.getElementsByTagName('ul')[0];
if(ul) {
ul.style.display = "block";
starMove(ul);
}
};
}
};
function starMove (obj) {
var Het = obj.offsetHeight;
if(Het<180){
obj.style.height = Het + 10 + 'px';
setTimeout("starMove('"+obj+"')", 10);
}
else{
return;
}
}
</script>
</head>
<body>
<ul class="nav">
<li><a href="#">首页</a></li>
<li><a href="#">前端课程</a>
<ul id="sub">
<li><a href="">HTML/CSS</a></li>
<li><a href="">JavaScript</a></li>
<li><a href="">JQuery</a></li>
</ul>
</li>
<li><a href="#">案例中心</a></li>
<li><a href="#">关于我们</a></li>
</ul>
</body>
</html>

应该就是obj那里的问题 -

设置时间超时那里引号有问题呃 -

obj是变量，加个引号就成字符串了
