HTML文本页面：
<template> <div id="app> <transition :name="direction" mode="out-in"> <!--动态获得transition 的name值--> <router-view class="app-view" wechat-title></router-view> </transition> </div> </template>
JS定义代码：定义在全局js文件里面
router.beforeEach((to, from, next) => { const list = ['home', 'group', 'user'] // 将需要切换效果的路由名称组成一个数组 const toName = to.name // 即将进入的路由名字 const fromName = from.name // 即将离开的路由名字 const toIndex = list.indexOf(toName) // 进入下标 const fromIndex = list.indexOf(fromName) // 离开下标 let direction = '' if (toIndex > -1 && fromIndex > -1) { // 如果下标都存在 if (toIndex < fromIndex) { // 如果进入的下标小于离开的下标，那么是左滑 direction = 'left' } else { direction = 'right' // 如果进入的下标大于离开的下标，那么是右滑 } } store.state.viewDirection = direction //这里使用vuex进行赋值 return next() })
在App.vue文件中，进行计算属性：
computed: { direction () { const viewDir = this.$store.state.viewDirection let tranName = '' if (viewDir === 'left') { tranName = 'view-out' } else if (viewDir === 'right') { tranName = 'view-in' } else { tranName = 'fade' } return tranName }, },
css3进行动画效果定义：使用sass
待定义引入样式文件：
// Variables $AnimateHook: "animated"; $AnimateDuration: 0.8s; // Mixins // Base Style .#{$AnimateHook} { -webkit-animation-duration: $AnimateDuration; animation-duration: $AnimateDuration; -webkit-animation-fill-mode: both; animation-fill-mode: both; // Modifier for infinite repetition &.infinite { -webkit-animation-iteration-count: infinite; animation-iteration-count: infinite; } } // Slide @-webkit-keyframes slideInLeft { from { -webkit-transform: translate3d(-100%, 0, 0); transform: translate3d(-100%, 0, 0); visibility: visible; } to { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } } @keyframes slideInLeft { from { -webkit-transform: translate3d(-100%, 0, 0); transform: translate3d(-100%, 0, 0); visibility: visible; } to { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } } .slideInLeft { -webkit-animation-name: slideInLeft; animation-name: slideInLeft; } @-webkit-keyframes slideInRight { from { -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0); visibility: visible; } to { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } } @keyframes slideInRight { from { -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0); visibility: visible; } to { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } } .slideInRight { -webkit-animation-name: slideInRight; animation-name: slideInRight; } @-webkit-keyframes slideOutLeft { from { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } to { visibility: hidden; -webkit-transform: translate3d(-100%, 0, 0); transform: translate3d(-100%, 0, 0); } } @keyframes slideOutLeft { from { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } to { visibility: hidden; -webkit-transform: translate3d(-100%, 0, 0); transform: translate3d(-100%, 0, 0); } } .slideOutLeft { -webkit-animation-name: slideOutLeft; animation-name: slideOutLeft; } @-webkit-keyframes slideOutRight { from { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } to { visibility: hidden; -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0); } } @keyframes slideOutRight { from { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } to { visibility: hidden; -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0); } } .slideOutRight { -webkit-animation-name: slideOutRight; animation-name: slideOutRight; } @-webkit-keyframes inRight { 0% { -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0) } to { -webkit-transform: translateZ(0); transform: translateZ(0) } } @keyframes inRight { 0% { -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0) } to { -webkit-transform: translateZ(0); transform: translateZ(0) } } @-webkit-keyframes outLeft { 0% { -webkit-transform: translateZ(0); transform: translateZ(0) } to { -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0) } } @keyframes outLeft { 0% { -webkit-transform: translateZ(0); transform: translateZ(0) } to { -webkit-transform: translate3d(100%, 0, 0); transform: translate3d(100%, 0, 0) } }
定义进入与离开的动画过渡：
.fade-enter-active, .fade-leave-active { transition: all .2s ease; } .fade-enter, .fade-leave-active { opacity: 0; } .view-in-enter-active, .view-out-leave-active { position: absolute; top: 0; width: 100%; padding-top: px2rem($titbarHeight); -webkit-animation-duration: .3s; animation-duration: .3s; -webkit-animation-fill-mode: both; animation-fill-mode: both; -webkit-backface-visibility: hidden; backface-visibility: hidden; } .view-in-enter-active { -webkit-animation-name: inRight; animation-name: inRight; } .view-out-leave-active { -webkit-animation-name: outLeft; animation-name: outLeft; }
