为啥跳转的时候不会盖住上一个页面，有什么办法吗

<template>
<div id="app">

<keep-alive>
  <transition :name="slideName" :duration="{ enter: slideTime, leave: slideTime }">
    <router-view></router-view>
  </transition>
</keep-alive>

</div>
</template>

<script>
export default {
name: "App",
data() {

return {
  slideName: 'slide-right',
  slideTime: 400
};

},
watch: {

// 使用watch 监听$router的变化
$route(to, from) {
  this.slideName = this.$slideName
}

}
};
</script>

<style>

app {

text-align: center;
width: 100%;
overflow: hidden;
position: relative;
}

Answer 1

一般来说，router-view只会渲染一个页面，检查下这两个页面是否存在重复代码（复制粘贴问题？）
