const router = new VueRouter({
    // 2. 定義路由
    routes:[{
        path: '/cashier', component: Page1, meta: {
            keepAlive: true // 需要被快取
        }
    },{
        path: '/Page2', component: Page2
    },{
        path:'/Page3', component: Page3
    }]
})

<transition>
    <keep-alive
 
>
        <router-view></router-view>
    </keep-alive>
</transition>
