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></ul></div>
</template><style scoped lang='scss'>
.home-category {width: 250px;height: 500px;background: rgba(0, 0, 0, 0.8);position: relative;z-index: 99;.menu {li {padding-left: 40px;height: 55px;line-height: 55px;&:hover {background: $xtxColor;}a {margin-right: 4px;color: #fff;&:first-child {font-size: 16px;}}.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>

2- 完成代码

<script setup>
import { useCategoryStore } from '@/stores/category'const categoryStore = useCategoryStore()</script><template><div class="home-category"><ul class="menu"><li v-for="item in categoryStore.categoryList" :key="item.id"><RouterLink to="/">{{ item.name }}</RouterLink><RouterLink v-for="i in item.children.slice(0, 2)" :key="i" to="/">{{ i.name }}</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 item.goods" :key="i.id"><RouterLink to="/"><img :src="i.picture" alt="" /><div class="info"><p class="name ellipsis-2">{{ i.name }}</p><p class="desc ellipsis">{{ i.desc }}</p><p class="price"><i>¥</i>{{ i.price }}</p></div></RouterLink></li></ul></div></li></ul></div>
</template>

banner轮播图实现

1. 熟悉组件

<script setup></script><template><div class="home-banner"><el-carousel height="500px"><el-carousel-item v-for="item in 4" :key="item"><img src=" alt=""></el-carousel-item></el-carousel></div>
</template><style scoped lang='scss'>
.home-banner {width: 1240px;height: 500px;position: absolute;left: 0;top: 0;z-index: 98;img {width: 100%;height: 500px;}
}
</style>

2. 获取数据渲染组件

1- 封装接口

/*** @description: 获取banner图* @param {*}* @return {*}*/
import  httpInstance  from '@/utils/http'
function getBannerAPI (){return request({url:'home/banner'})
}

2- 获取数据渲染模版

<script setup>
import { getBannerAPI } from '@/apis/home'
import { onMounted, ref } from 'vue'const bannerList = ref([])const getBanner = async () => {const res = await getBannerAPI()console.log(res)bannerList.value = res.result
}onMounted(() => getBanner())</script><template><div class="home-banner"><el-carousel height="500px"><el-carousel-item v-for="item in bannerList" :key="item.id"><img :src="item.imgUrl" alt=""></el-carousel-item></el-carousel></div>
</template>

<script setup></script><template><div class="home-panel"><div class="container"><div class="head"><!-- 主标题和副标题 --><h3>新鲜好物<small>新鲜出炉 品质靠谱</small></h3></div><!-- 主体内容区域 --><div> 主体内容 </div></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;}}}
}
</style>

2. 完整代码

<script setup>defineProps({title: {type: String,default: ''},subTitle: {type: String,default: ''}
})</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 --><slot name="main" /></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;}}}
}
</style>

新鲜好物实现

1. 准备模版

</template><style scoped lang='scss'>
.goods-list {display: flex;justify-content: space-between;height: 406px;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;}.price {color: $priceColor;}}
}
</style>

2. 封装接口

/*** @description: 获取新鲜好物* @param {*}* @return {*}*/
export const findNewAPI = () => {return httpInstance({url:'/home/new'})
}

3. 获取数据渲染模版

<script setup>
import HomePanel from './HomePanel.vue'
import { getNewAPI } from '@/apis/home'
import { ref } from 'vue'
const newList = ref([])
const getNewList = async () => {const res = await getNewAPI()newList.value = res.result
}getNewList()
</script><template><HomePanel title="新鲜好物" sub-title="新鲜出炉 品质靠谱"><template #main><ul class="goods-list"><li v-for="item in newList" :key="item.id"><RouterLink :to="`/detail/${item.id}`"><img :src="item.picture" alt="" /><p class="name">{{ item.name }}</p><p class="price">&yen;{{ item.price }}</p></RouterLink></li></ul></template></HomePanel>
</template>

人气推荐实现

1. 封装接口

/*** @description: 获取人气推荐* @param {*}* @return {*}*/
export const getHotAPI = () => {return  httpInstance('home/hot', 'get', {})
}

2. 获取数据渲染模版

<script setup>
import HomePanel from './HomePanel.vue'
import { getHotAPI } from '@/apis/home'
import { ref } from 'vue'
const hotList = ref([])
const getHotList = async () => {const res = await getHotAPI()hotList.value = res.result
}
getHotList()</script><template><HomePanel title="人气推荐" sub-title="人气爆款 不容错过"><ul class="goods-list"><li v-for="item in hotList" :key="item.id"><RouterLink to="/"><img v-img-lazy="item.picture" alt=""><p class="name">{{ item.title }}</p><p class="desc">{{ item.alt }}</p></RouterLink></li></ul></HomePanel>
</template><style scoped lang='scss'>
.goods-list {display: flex;justify-content: space-between;height: 426px;li {width: 306px;height: 406px;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;}.desc {color: #999;font-size: 18px;}}
}
</style>

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urlconsole.log(el, binding.value)const { stop } = useIntersectionObserver(el,([{ isIntersecting }]) => {console.log(isIntersecting)if (isIntersecting) {// 进入视口区域el.src = binding.valuestop()}},)}})}
}

2. 注册全局指令

}
</style>

2- 封装接口
