基于Vue的頁面切換左右滑動效果，具體內容如下
HTML文本頁面：
<template> <div id="app> <transition :name="direction" mode="out-in"> <!--動態獲得transition 的name值--> <router-view class="app-view" wechat-title></router-view> </transition> </div> </template>
JS定義代碼：定義在全局js文件里面
router.beforeEach((to, from, next) => {
const list = ['home', 'group', 'user'] // 將需要切換效果的路由名稱組成一個數組
const toName = to.name // 即將進入的路由名字
const fromName = from.name // 即將離開的路由名字
const toIndex = list.indexOf(toName) // 進入下標
const fromIndex = list.indexOf(fromName) // 離開下標
let direction = ''
if (toIndex > -1 && fromIndex > -1) { // 如果下標都存在
if (toIndex < fromIndex) { // 如果進入的下標小于離開的下標，那么是左滑
direction = 'left'
} else {
direction = 'right' // 如果進入的下標大于離開的下標，那么是右滑
}
}
store.state.viewDirection = direction //這里使用vuex進行賦值
return next()
})
在App.vue文件中，進行計算屬性：
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進行動畫效果定義：使用sass
待定義引入樣式文件：
// 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

定義進入與離開的動畫過渡：
.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;
}
