mui底部導航欄

mui是通過mui-active的class屬性來表示激活狀態（改變該按鈕的顏色）

 <router-link class="mui-tab-item mui-active" :to="{name:'member'}">
       <span class="mui-icon icon-myhuiyuan"></span>
       <span class="mui-tab-label">會員</span>
 </router-link>

配合router-link的linkActiveClass屬性，就能在每次點擊后並且跳轉后，改變樣式。

let router = new VueRouter({ linkActiveClass:'mui-active', //router-link成功后，就給該按鈕加上mui-active屬性。 routes: [ //VueRouter：配置路由規則
        { path: '/', redirect: { name: 'home' } }, //重定向
        { name: 'home', path: '/home', component: Home },//首頁
        { name:'member',path:'/member',component: Member}, //會員
        { name: 'shopcart',path:'/shopcart',component:Shopcart}, //購物車
        { name: 'search',path:'/search',component:Search}, //查找
        { name:'news.list',path:'/news/list',component:NewsList}, //新聞列表
        { name:'news.detail',path:'/news/detail',component:NewsDetail}, //新聞詳情
 ] });
