jquery+css实现简单的评分功能

今天研究了下简单的评分功能,参考了下"http://www.lanxyou.info/star-rating-new-method/",感觉比较简单易用,之后自己做了下优化处理。

先看下效果图:

原理:橙色星宽度/父容器宽度 * 100 = 分值

功能:鼠标悬浮时,其左侧星星点亮

   鼠标滑过时,其左侧星星点亮

   鼠标点击时,其左侧星星点亮

     鼠标移开后,默认记忆上次点击的橙色星宽度

所需图片:

实现源码:

        rating.mouseover(function(e){
            var overWidth=parseInt(((e.pageX-leftRating)/width)*100,10);
