Vue中切换页面时的过渡动画

 

1. 我们需要给各个页面定义层级,在切换路由时判断用户是进入哪一层页面,如果用户进入更高层级那么做前进动画,如果用户退到低层级那么做后退动画。

   import Vue from 'vue';
   import Router from 'vue-router';
   import Home from '@/pages/home/Home';
   import List from '@/pages/list/List';
   import Detail from '@/pages/detail/Detail';
   
   Vue.use(Router);
   
   export default new Router({
     routes: [
       {
         path: '/',
         name: 'Home',
         meta:{index:0},
         component: Home
       },
       {
         path: '/list',
         name: 'List',
         meta:{index:1},
         component: List
       },
       {
         path: '/detail',
         name: 'Detail',
         meta:{index:2},
         component: Detail
       }
     ]
   });

    

2. 监控路由跳转,判断切换页面之间的层级关系,并以此来判断路由前进或者后退.

    

3. 编写slide-left 和 slide-right 类的动画

   .slide-right-enter-active,
   .slide-right-leave-active,
   .slide-left-enter-active,
   .slide-left-leave-active {
     will-change: transform;
     transition: all 500ms;
     position: absolute;
   }
   .slide-right-enter {
     opacity: 0;
     transform: translate3d(-100%, 0, 0);
   }
   .slide-right-leave-active {
     opacity: 0;
     transform: translate3d(100%, 0, 0);
   }
   .slide-left-enter {
     opacity: 0;
     transform: translate3d(100%, 0, 0);
   }
   .slide-left-leave-active {
     opacity: 0;
     transform: translate3d(-100%, 0, 0);
   }
