vue的路由切换动画

0.main.js引入animate.css

1.给router-view标签外层加上transition标签，并且router-view标签要改成<router-view></router-view>

2.在transition标签加上两个类：enter-active-class  和 leave-active-class 

   <transition enter-active-class="animated bounce" leave-active-class="animated hinge">
       <router-view></router-view>
     </transition>
