静态结构搭建和分类实现

1. 整体结构创建

![image.png](

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>
  <div> HomeCategory </div>
</template>

2- Home模块入口组件中引入并渲染

<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>

2. 分类实现

1- 准备详细模版

<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>
                  <p class="price"><i>¥</i>200.00</p>
                </div>
              </RouterLink>
            </li>
          </ul>
        </div>
      </li>

懒加载指令实现

1. 封装全局指令

// 定义懒加载插件
import { useIntersectionObserver } from '@vueuse/core'

export const lazyPlugin = {
  install (app) {
    // 懒加载指令逻辑
    app.directive('img-lazy', {
      mounted (el, binding) {
        // el: 指令绑定的那个元素 img
        // binding: binding.value  指令等于号后面绑定的表达式的值  图片url
        console.log(el, binding.value)
        const { stop } = useIntersectionObserver(
          el,
          ([{ isIntersecting }]) => {
            console.log(isIntersecting)
            if (isIntersecting) {
              // 进入视口区域
              el.src = binding.value
              stop()
            }
          },
        )
      }

        height: 29px;
      }

      .price {
        color: $priceColor;
        font-size: 20px;
      }
    }
  }
}
</style>

2- 封装接口

/**
 * @description: 获取所有商品模块
 * @param {*}
 * @return {*}
 */
export const getGoodsAPI = () => {
  return httpInstance({
    url: '/home/goods'
  })
}

3- 获取并渲染数据

<script setup>
import HomePanel from './HomePanel.vue'
import { getGoodsAPI } from '@/apis/home'
import { ref } from 'vue'
const goodsProduct = ref([])
const getGoods = async () => {
  const { result } = await getGoodsAPI()
  goodsProduct.value = result
}
onMounted( ()=> getGoods() )
</script>

<template>
  <div class="home-product">
    <HomePanel :title="cate.name" v-for="cate in goodsProduct" :key="cate.id">
      <div class="box">
        <RouterLink class="cover" to="/">
          <img :src="cate.picture" />
          <strong class="label">
            <span>{{ cate.name }}馆</span>
            <span>{{ cate.saleInfo }}</span>
          </strong>
        </RouterLink>
        <ul class="goods-list">
          <li v-for="goods in cate.goods" :key="good.id">
            <RouterLink to="/" class="goods-item">
              <img :src="goods.picture" alt="" />
              <p class="name ellipsis">{{ goods.name }}</p>
              <p class="desc ellipsis">{{ goods.desc }}</p>
              <p class="price">&yen;{{ goods.price }}</p>
            </RouterLink>
          </li>
        </ul>
      </div>
    </HomePanel>
  </div>
</template>

2. 图片懒加载

<div class="home-product">
  <HomePanel :title="cate.name" v-for="cate in goodsProduct" :key="cate.id">
    <div class="box">
      <RouterLink class="cover" to="/">
        <!-- 指令替换 -->
        <img v-img-lazy="cate.picture" />
      </RouterLink>
      <ul class="goods-list">
        <li v-for="goods in cate.goods" :key="goods.id">
          <RouterLink to="/" class="goods-item">
             <!-- 指令替换 -->
            <img v-img-lazy="goods.picture" alt="" />
          </RouterLink>
        </li>
      </ul>
    </div>
  </HomePanel>
</div>

GoodsItem组件封装

1. 封装组件


<script setup>
defineProps({
  goods: {
    type: Object,
    default: () => { }
  }
})
</script>

<template>
  <RouterLink to="/" class="goods-item">
    <img :src="goods.picture" alt="" />
    <p class="name ellipsis">{{ goods.name }}</p>
    <p class="desc ellipsis">{{ goods.desc }}</p>
    <p class="price">&yen;{{ goods.price }}</p>
  </RouterLink>
</template>


<style scoped lang="scss">
.goods-item {
  display: block;
  width: 220px;
  padding: 20px 30px;
  text-align: center;
  transition: all .5s;

  &:hover {
    transform: translate3d(0, -3px, 0);
    box-shadow: 0 3px 8px rgb(0 0 0 / 20%);
  }

  img {
    width: 160px;
    height: 160px;
  }

  p {
    padding-top: 10px;
  }

  .name {
    font-size: 16px;
  }

  .desc {
    color: #999;
    height: 29px;
  }

  .price {
    color: $priceColor;
    font-size: 20px;
  }
}
</style>

2. 使用组件

<ul class="goods-list">
  <li v-for="goods in cate.goods" :key="item.id">
    <GoodsItem :goods="goods" />
  </li>
</ul>
