本篇实现三段式界面

公共布局文件

首先在src下新建layoutPc文件夹，再给layoutPc新建组件 header 、bottm、main三个文件基本确定了一个页面的基本架子，然后再新建一个index.vue文件

comment/AppMain.vue

<template>
  <section class="app-main">
    <transition name="fade-transform" mode="out-in">
      <keep-alive >
        <router-view v-if="!$route.meta.link" :key="key" />
      </keep-alive>
    </transition>
    <iframe-toggle />
  </section>
</template>

<script>

export default {
  name: 'AppMain',
  components: {  },
  computed: {
    key() {
      return this.$route.path
    }
  }
}
</script>

bootom/index.vue

<template>
  <div class="bottom-wrapper">
    <el-row>
      <el-col :span="8">
        <div>
          友情链接
        </div>
      </el-col>
      <el-col :span="8">
        <p>© {{ new Date().getFullYear() }} </p>
        <div>
          <div class="web-title">
            <svg-icon icon-class="web" size="1.1875rem"></svg-icon>
            网站资讯
          </div>

        </div>

      </el-col>
      <el-col :span="8">
        <div>
          广告位招租
        </div>

      </el-col>
    </el-row>

  </div>
</template>

<script>

export default {
  name: "bottom",
  data() {
    return {
    }
  },
  computed:{

  },
  mounted() {

  },
  methods:{

  }
};
</script>

header/index.vue

<template>
  <div class="header-wrapper show up">
    headers
  </div>
</template>

<script>

export default {
  name: "headers",
  data() {
    return {
    }
  },
  components: {
  },

};
</script>

layoutPc/index.vue
引入三个组件

<template>
  <div >
    <Header/>
    <app-main/>
    <Bottom/>
  </div>
</template>
<script setup>
import Header from "@/layoutPc/header/index";
import Bottom from "@/layoutPc/bottom/index";
import AppMain from "@/layoutPc/comment/AppMain";
export default {
  name: "layoutPc",
  components: {
    Header,
    Bottom,
    AppMain
  },
}
</script>

router/index.js

路由配置

import Layout from '@/layoutPC/index'

export const constantRoutes = [
  {
    path: '/',
    component: Layout,
    children: [
      {
        path: '/index',
        component: () => import('@/views/index.vue')
      },
    ]
  },
 ]
