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> --></li></ul></div>
</template><style scoped lang='scss'>
.home-category {width: 250px;height: 500px;background: #f2f2f2;position: relative;z-index: 99;.menu {li {padding-left: 40px;height: 55px;line-height: 55px;text-align: left;padding-right: 15px;border-bottom: solid .1px #000;.iconfont{font-size: 22px;line-height: 55px;margin-right: 10px;top: 5px;color: rgb(0, 110, 255);}&:hover {background: $lygColor;}a {position: absolute;margin-right: 4px;color: #000;&:first-child {font-size: 16px;}}.more{float: right;font-size: 18px;}.layer {width: 990px;height: 500px;background: rgba(255, 255, 255, 0.8);position: absolute;left: 250px;top: 0;display: none;padding: 0 15px;h4 {font-size: 20px;font-weight: normal;line-height: 80px;small {font-size: 16px;color: #666;}}ul {display: flex;flex-wrap: wrap;li {width: 310px;height: 120px;margin-right: 15px;margin-bottom: 15px;border: 1px solid #eee;border-radius: 4px;background: #fff;&:nth-child(3n) {margin-right: 0;}a {display: flex;width: 100%;height: 100%;align-items: center;padding: 10px;&:hover {background: #e3f9f4;}img {width: 95px;height: 95px;}.info {padding-left: 10px;line-height: 24px;overflow: hidden;.name {font-size: 16px;color: #666;}.desc {color: #999;}.price {font-size: 22px;color: $priceColor;i {font-size: 16px;}}}}}}}// 关键样式  hover状态下的layer盒子变成block&:hover {.layer {display: block;}}}}
}
</style>

四、banner功能实现

接口封装

在 api 目录下创建 home 目录然后创建 banner.js 文件

import http from '@/utils/http'export function getBannerAPI () {return http({url: '/home/banner/list',method: 'get',})
}

代码示范

HomeBanner.vue

<script setup>
import { getBannerAPI } from '@/api/home/banner'
import { onMounted, ref } from 'vue'const bannerList = ref([])const getBanner = async () => {const res = await getBannerAPI()console.log(res)bannerList.value = res.data
}onMounted(() => getBanner());
console.log(bannerList)
</script><template><div class="home-banner"><el-carousel height="500px"><el-carousel-item v-for="item in bannerList" :key="item.id"><img :src="require(`@/assets/img/${item.img1}.jpg`)" alt=""></el-carousel-item></el-carousel></div>
</template><style scoped lang='scss'>
.home-banner {width: 1127px;height: 500px;position: absolute;left: 250px;top: 185px;z-index: 98;img {width: 100%;height: 500px;}
}
</style>

五、创建公共组件

创建文件

在 views/Home/components 路径下创建 HomePanel.vue 文件

<script setup>
//定义 Props，主标题和副标题
defineProps({title: {type: String},subTitle: {type: String}
})
</script><template><div class="home-panel"><div class="container"><div class="head"><!-- 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;color: #999;margin-left: 20px;}}}

})
</script><template><HomePanel title="精选商品" sub-title="人气精选 不容错过"><!-- 下面是插槽主体内容模版 --><ul class="goods-list"><li v-for="item in hotList" :key="item.id"><RouterLink to="/"><img :src="require(`@/assets/img/${item.picture1}.jpg`)" :alt="item.alt" /><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;transition: all .5s;&: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;}.price {color: $priceColor;}}
}
