新增功能，磁盘格式化，层级面包屑跳转，视频预览优化

主要记录一下面包屑的实现思路

2.1 面包屑渲染

复制代码

    <el-breadcrumb separator-class="el-icon-arrow-right">      <el-breadcrumb-item>        <el-link :underline="false" @click="skipCrumbs(0)">根目录</el-link>      </el-breadcrumb-item>        <el-breadcrumb-item v-for="(item,index) in crumbsList":key="index">          <el-link :underline="false" @click="skipCrumbs(item.id)">{{item.name}}</el-link>        </el-breadcrumb-item>    </el-breadcrumb>

复制代码

   定义vue dataallCrumbsList: [],crumbsList: [],
