var rating = (function(){

var init = function(el,num)//el表示是哪一个评分，num表示默认需要点亮几个星星
{
var $rating = $(el),
$item = $rating.find('.rating-item');//找父标签，遍历所有星星
// 初始化
lightOn($item,num);
// 事件绑定
$rating.on('mouseover','.rating-item',function()
{//将子元素rating-item的事件委托给父元素rating处理
lightOn($item,$(this).index()+1);

知道了，
.rating-item{
display: inline-block;
width: 66px;
height: 76px;
background: url(img/rating.png) no-repeat;
cursor:pointer;/*光标呈现一只手*/
}
但是为什么是inline-block还是有点疑惑，inline-block不是不单独占一行，共享同一行的嘛
