前一篇文章( jQuery实现轮播效果(一) - 基础)讲到了怎样用jquery来实现一个简单的jquery轮播效果，基本的功能已经实现了，效果看起来还令人满意，唯一不足的就是：每次需要轮播效果时，要将代码复制粘贴过去，如果有些部分需要修改（例如：轮播时的动画效果，前一篇使用的是jquery的淡入淡出效果，如果改成滑动效果，不可避免的要修改js代码），那么就需要对js代码进行修改，对我所写的jquery轮播效果的js代码不熟悉的程序员来说，修改这些js确实很困难。轮播插件所要实现的目标之一就是插件可以灵活配置（不光只是本篇文章的插件），程序员只需要写少量的代码就可以实现丰富的功能，这当然是一件很好的事情。本篇文章的轮播插件的html和css部分需要程序员自己编写，而实现效果的js只需要少量的编写。
