基于Vue实现页面切换左右滑动效果

<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>

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() })

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   },  },
