基于Vue实现页面切换左右滑动效果

基于Vue的页面切换左右滑动效果，具体内容如下

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;
}
