1. Home-整体结构搭建和分类实现

1- 按照结构新增五个组件，准备最简单的模版，分别在Home模块的入口组件中引入

• HomeCategory
• HomeBanner
• HomeNew
• HomeHot
• HomeProduct

<script setup >
</script>

<template>
    我是产品页面        
</template>
    
<style>
</style>

2- Home模块入口组件中引入并渲染 Home/index.vue

<script setup >
import HomeCategory from './components/HomeCategory.vue'
import HomeBanner from './components/HomeBanner.vue'
import HomeNew from './components/HomeNew.vue'
import HomeHot from './components/HomeHot.vue'
import homeProduct from './components/HomeProduct.vue'
</script>

<template>
  <div class="container">
    <HomeCategory />
    <HomeBanner />
  </div>
  <HomeNew />
  <HomeHot />
  <homeProduct />
</template>
    
<style lang='scss'>
</style>

2. 分类实现

1- 准备详细模版 HomeCategory.vue

<script setup>

</script>

<template>
  <div class="home-category">
    <ul class="menu">
      <li v-for="item in 9" :key="item">
        <RouterLink to="/">居家</RouterLink>
        <RouterLink v-for="i in 2" :key="i" to="/">南北干货</RouterLink>
        <!-- 弹层layer位置 -->
        <div class="layer">
          <h4>分类推荐 <small>根据您的购买或浏览记录推荐</small></h4>
          <ul>
            <li v-for="i in 5" :key="i">
              <RouterLink to="/">
                <img alt="" />
                <div class="info">
                  <p class="name ellipsis-2">
                    男士外套
                  </p>
                  <p class="desc ellipsis">男士外套，冬季必选</p>

          </ul>
        </div>
      </li>
    </ul>
  </div>
</template>

      <li v-for="item in categoryStore.categoryList" :key="item.id">
        <!-- 遍历类别 -->
        <RouterLink to="/">{{ item.name }} </RouterLink>
        <RouterLink v-for="i in item.children.slice(0, 2)" :key="i" to="/">{{ i.name }}</RouterLink>
