vue使用keep-alive实现组件切换时保存原组件数据方

<keep-alive>
 <router-view />
</keep-alive>

//ManageFiles组件需要重新挂起刷新数据，而ManageUploadFile为上传文件组件，故想之存活
{
 path:'files',
 name:'ManageFiles',
 ponent: () => import('../pages/course/manage/resource/files/Files'),
},
{
 path:'uploadfile',
 name:'ManageUploadFile',
 meta:{
 keepAlive:true  //是否存活标志
 },
 ponent: () => import('../pages/course/manage/resource/files/UploadFile'),
},

<template>
 <div class="manageResource">
 <keep-alive>
  <router-view v-if="$route.meta.keepAlive" />
 </keep-alive>
 <router-view v-if="!$route.meta.keepAlive" />
 </div>
</template>

 <!--动态组件-ponent使用-->
 <div class="app">
 <ul>
 <li @click="currView='home'">首页</li>
 <li @click="currView='abount'">关于我们</li>
 </ul>
 <!--通过keep-alive 保留数据值 填写数据时切换到其他页面，后返回当前页数据保留-->
 <keep-alive>
 <ponent :is="currView"></ponent>
 </keep-alive>
 </div>

<script type="text/x-Template" id="homeTemp">
  <h2>首页数据</h2>
</script>
<script type="text/x-Template" id="abountTemp">
  <h2>关于我们数据<input type="text"/></h2>
</script>

<script type="text/javascript">
 var vm=new Vue({
 el:'.app',

 ponents:{

   template:"#homeTemp"
