老师, 因为您没有讲到切换路由时的动画 , 我自行百度做了下。路由动画实现了，但是还是有一些小问题，当mode="in-out"的时候，页面切换时会出现两个页面的重叠，进入动画比较流畅，但返回动画却有一些延迟，点了要等一会儿会儿才会响应，搞不明白了唉

<template>
  <div id="app">
    <transition
      :name="transitionName"
      mode="in-out"
    >

      <keep-alive exclude="Details">
        <router-view class="child-view"></router-view>
      </keep-alive>
      
    </transition>
  </div>
</template>

<script>
export default {
  name: "app",
  data() {
    return {
      transitionName: "slide-left"
    };
  },
  watch: {
    $route(to, from) {
      const toDepth = to.path.split("/").length;
      const fromDepth = from.path.split("/").length;
      this.transitionName = toDepth < fromDepth ? "slide-right" : "slide-left";
    }
  }
};
</script>

<style scoped>
.child-view {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  transition: all 0.6s cubic-bezier(0.55, 0, 0.1, 1);
}
.slide-left-enter,
.slide-right-leave-active {
  opacity: 0;
  -webkit-transform: translate(-80px, 0);
  transform: translate(-80px, 0);
}
.slide-left-leave-active,
.slide-right-enter {
  opacity: 0;
  -webkit-transform: translate(100%, 0);
  transform: translate(100%, 0);
}
</style>
