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 } ] });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.
<template> <div id="app"> <transition :name="transitionName"> <router-view></router-view> </transition> </div> </template> <script> export default { name: 'App', data(){ return { transitionName:'' } }, watch: {//使用watch 监听$router的变化 $route(to, from) { //如果to索引大于from索引,判断为前进状态,反之则为后退状态 if(to.meta.index > from.meta.index){ //设置动画名称 this.transitionName = 'slide-left'; }else{ this.transitionName = 'slide-right'; } } } } </script>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); }至此已成功加入过渡动画效果。。。
