用JS实现图片轮播的问题,谢谢了

我又来问问题了,(自学JS没人请教也是尴尬,好像找个师傅啊),下面是问题 谢谢了
这是图片轮播代码,麻烦大家,在浏览器打开看下,这样能说清楚问题

鼠标放在 1,2,3,4上后,上面对应的图片切图,下面的小图片带边框
鼠标放在下面的小图片上,上面的大图也会切图
(只设置了onmousemove并没onmouseout)
那么问题来了
假如你鼠标放在2那,下面对应的第二个图会出现边框,然后你把鼠标移到下面第三个图上,结果下面第三个图也出现边框了,一下两个边框
同理鼠标一开始放在下面第二个图上,然后上面对应的数字2背景变黑,这个时候,鼠标移到上面数字3上面.同时3的背景色也变黑了 ,
怎么解决这个问题呢,加上onmouseout可以吗
怎样才能让第一个函数工作的时候清除第二个函数带来的效果,第二个函数工作的时候清除第一个函数带来的效果?
真心求教////

    一个函数就好了吧,搞那么麻烦,mouseover的时候同时清空其他选项样式

    最简单是,获取当前选中节点的父节点,如何遍历你的四个节点全部置为none,再给当前获取到的节点为block。
    通过冒泡方法来完成。冒泡是比较基础的了,如果不会,建议先去看看javascript的基础。

    可以用jQuery操作你的js,现在对原生js都不记得多少了。
