乐意购项目前端开发 #4

一、Home页面组件结构

结构拆分

?创建组件

在 views/Home 目录下创建component 目录, 然后在该目录下创建5个组件:?左侧分类(HomeCategory.vue)、Banner(HomeBanner.vue)、精选商品(HomeHot.vue)、低价商品(Homecheap.vue)、最新上架(HomeNew.vue)

引用组件

修改 views/Home/index.vue 的代码

<template>
  <div class="container">
    <HomeCategory></HomeCategory>
    <HomeBanner></HomeBanner>
  </div>
  <HomeHot></HomeHot>
  <HomeCheap></HomeCheap>
  <HomeNew></HomeNew>
</template>

<script>
import HomeBanner from './component/HomeBanner.vue'
import HomeCategory from './component/HomeCategory.vue'
import HomeHot from './component/HomeHot.vue'
import HomeNew from './component/HomeNew.vue'
import HomeCheap from './component/HomeCheap'
export default {
  components:{
    HomeBanner,
    HomeCategory,
    HomeHot,
    HomeNew,
    HomeCheap
  }

}
</script>

<style>

</style>

二、安装Pinia

添加依赖

pinia依赖和持久化插件

npm install pinia
npm install pinia-plugin-persist

创建文件

在 stores 目录下创建 category.js 文件

import { ref } from 'vue'
import { defineStore } from 'pinia'

引入

修改 main.js 文件

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import { createPinia } from 'pinia' 
import piniaPersist from 'pinia-plugin-persist'
import ElementPlus from 'element-plus'
import "@/assets/iconfont/iconfont.js"
import "@/assets/iconfont/iconfont.css"

// import './styles/element/index.scss'

const pinia = createPinia()
pinia.use(piniaPersist)
const app = createApp(App)

app.use(store).use(router).use(pinia).use(ElementPlus).mount('#app')

三、分类功能实现

封装接口

在 api 目录下创建 home 目录然后创建 category.js 文件

import http from '@/utils/http'

export function getCategoryAPI () {
  return http({
    url: '/home/category/list',
    method: 'get',
  })
}

前提: 后端要返回相应的数据

修改 /store/category.js

import { ref } from 'vue'
import { defineStore } from 'pinia'
import { getCategoryAPI } from '@/api/home/category'

export const useCategoryStore = defineStore('category', () => {
    // 导航列表数据管理
    //state 导航列表数据
    const categoryList = ref([])

    // action 获取导航数据的方法
    const getCategory = async () => {
        const res = await getCategoryAPI();
        console.log(res);
        categoryList.value = res.data;
    }

    return {
        categoryList, getCategory
    }
})

代码示范

HomeCategory.vue

<script setup>
import { useCategoryStore } from '@/store/category'
const categoryStore = useCategoryStore()
console.log(categoryStore);
</script>

<template>
  <div class="home-category">
    <ul class="menu">
      <li v-for="item in categoryStore.categoryList" :key="item.id">
        <i :class=item.icon></i>
        <router-link to="/">{{ item.categoryName }}</router-link>
        <span class="more">
          <a href="/">></a>
        </span>
        <!-- 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> -->

  })
}

    },
    subTitle: {
        type: String
    }

    <!-- 主标题和副标题 -->
    <h3>
      {{title}}<small>{{ subTitle }}</small>
    </h3>
  </div>
  <!-- 主体内容区域 插槽-->
  <slot/>
</div>

  </div>
</template>

<style scoped lang='scss'>
.home-panel {
  background-color: #fff;

  .head {
    padding: 40px 0;
    display: flex;
    align-items: flex-end;

    h3 {
      flex: 1;
      font-size: 32px;
      font-weight: normal;
      margin-left: 6px;
      height: 35px;
      line-height: 35px;

      small {
        font-size: 16px;

    const res = await getHotAPI()
    console.log(res)
    hotList.value = res.data
}

onMounted(() => {
    getHotList()
})
</script>

<template>
    <HomePanel title="精选商品" sub-title="人气精选 不容错过">

                    <p class="name">{{ item.goodsName }}</p>
                    <p class="price">&yen;{{ item.price }}</p>
                </RouterLink>
            </li>
        </ul>
    </HomePanel>
</template>


<style scoped lang='scss'>
.goods-list {
  display: flex;
  justify-content: space-between;
  height: 406px;
  width: 100%;

  li {
    width: 306px;
    height: 406px;

    background: #f0f9f4;

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

    img {
      width: 306px;
      height: 306px;
    }

    p {
      font-size: 22px;
      padding-top: 12px;
      text-align: center;
      text-overflow: ellipsis;
      overflow: hidden;
      white-space: nowrap;
      color: #000;
