我就废话不多说了，直接上代码吧！

// 视图切换动画逻辑
let history = window.sessionStorage
let historyCount = history.getItem('count') * 1 || 0
function routerTransition (to, from) {
 const toIndex = history.getItem(to.name)
 const fromIndex = history.getItem(from.name)
 let direction = 'forward'
 if (toIndex) {
 if (toIndex >= fromIndex || !fromIndex) {
  store.commit('UPDATE_DIRECTION', {direction})
 } else {
  direction = 'reverse'
  store.commit('UPDATE_DIRECTION', {direction})
 }
 } else {
 ++historyCount
 history.setItem('count', historyCount)
 to.path !== '/' && history.setItem(to.name, historyCount)
 direction = 'forward'
 store.commit('UPDATE_DIRECTION', {direction})
 }
}
router.beforeEach(function (to, from, next) {
 routerTransition(to, from)
 next()
})
