## 底部导航样式修改 ##

第一步：

## 顶部导航矩阵 ##

*  v-for取代多次复制

*  动态绑定样式

*  添加8个

*  \{ \{\}\}和\{\}的区别  
    \{ \{\}\}：

    不带任何符号：

## 首页轮播图 ##

准备图片数组：

v-for：下面这种写法图片是无法显示出来的

加上require：

展示下标为指定值的图片：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2E3NzIzMDQ0MTk_size_16_color_FFFFFF_t_70_pic_center 14]  
索引轮播图的实现思路就是：动态改变n的值，让其每隔1秒钟就+1.就实现了轮播的效果了

*  定时器的清除  
    当切换到其他页面时，当前页面的定时器应该将其清除掉。  
    先定义一个定时器属性：

    组件destroyed销毁时调用定时器的清除方法：
