2- 封装接口
/**

* @param {Number} id - 商品id
* @param {Number} type - 1代表24小时热销榜 2代表周热销榜
* @param {Number} limit - 获取个数
*/
export const fetchHotGoodsAPI = ({ id, type, limit = 3 }) => {
return request({
url:'/goods/hot',
params:{
id,
type,
limit
}
})
}
3- 获取基础数据渲染模版
<script setup>
import { ref } from 'vue'
import { getHotGoodsAPI } from '@/apis/detail'
import { useRoute } from 'vue-router'
const goodList = ref([])
const route = useRoute()
const getHotList = async () => {
const res = await getHotGoodsAPI({
id: route.params.id,
type: 1
})
goodList.value = res.result
}
getHotList()
</script>
<template>
<div class="goods-hot">
<h3> 24小时热榜 </h3>
<!-- 商品区块 -->
<RouterLink :to="`/detail/${item.id}`" class="goods-item" v-for="item in goodList" :key="item.id">
<img :src="item.picture" alt="" />
<p class="name ellipsis">{{ item.name }}</p>
<p class="desc ellipsis">{{ item.desc }}</p>
<p class="price">¥{{ item.price }}</p>
</RouterLink>
</div>
// type适配不同类型热榜数据
const props = defineProps({
type: {
type: Number, // 1代表24小时热销榜 2代表周热销榜 3代表总热销榜 可以使用type去适配title和数据列表
default: 1
}
})
const res = await fetchHotGoodsAPI({
id: route.params.id,
type: props.type
})
2- 使用组件传入不同的type
<!-- 24小时热榜 -->
<GoodHot :type="1" />
<!-- 周热榜 -->
<GoodHot :type="2" />
const TITLEMAP = {
1: '24小时热榜',
2: '周热榜',
}
const title = computed(() => TITLEMAP[props.type])
<h3>{{ title }}</h3>
通过小图切换大图
思路:维护一个数组图片列表,鼠标划入小图记录当前小图下标值,通过下标值在数组中取对应图片
,显示到大图位置。
1- 准备模版
<script setup>
// 图片列表
const imageList = [
"https://yanxuan-item.nosdn.127.net/d917c92e663c5ed0bb577c7ded73e4ec.png",
"https://yanxuan-item.nosdn.127.net/e801b9572f0b0c02a52952b01adab967.jpg",
"https://yanxuan-item.nosdn.127.net/b52c447ad472d51adbdde1a83f550ac2.jpg",

"https://yanxuan-item.nosdn.127.net/f881cfe7de9a576aaeea6ee0d1d24823.jpg"
]
</script>
<template>
<div class="goods-image">
<!-- 左侧大图-->
<div class="middle" ref="target">
<img :src="imageList[0]" alt="" />
<!-- 蒙层小滑块 -->
<div class="layer" :style="{ left: `0px`, top: `0px` }"></div>

</ul>

<div class="large" :style="[
{

},
]" v-show="false"></div>
</div>

margin-bottom: 15px;
cursor: pointer;
&:hover,
&.active {
border: 2px solid $xtxColor;

}
}
}
</style>
2- 实现逻辑
<script setup>
import { ref } from 'vue'
// 实现鼠标移入交互
const curIndex = ref(0)
const mouseEnterFn = (i) => curIndex.value = i
</script>
<template>
<div class="goods-image">
<!-- 小图列表 -->
<ul class="small">
<li v-for="(img, i) in imageList"
:key="i"
@mouseenter="mouseEnterFn(i)"
:class="{ active: i === curIndex }">
<img :src="img" alt="" />
</li>
</ul>
</div>
</template>
放大镜效果实现
放大镜效果实现 - 滑块跟随鼠标移动
思路:获取到当前的鼠标在盒子内的相对位置(useMouseInElement)
,控制滑块跟随鼠标移动(left/top)
<script setup>
import { ref, watch } from 'vue'
import { useMouseInElement } from '@vueuse/core'
// 图片列表
const imageList = [

"https://yanxuan-item.nosdn.127.net/f881cfe7de9a576aaeea6ee0d1d24823.jpg"
]
// 1.小图切换大图显示
const activeIndex = ref(0)
const enterhandler = (i) => {
activeIndex.value = i
}
// 2. 获取鼠标相对位置
const target = ref(null)
const { elementX, elementY, isOutside } = useMouseInElement(target)
// 3. 控制滑块跟随鼠标移动(监听elementX/Y变化,一旦变化 重新设置left/top)
const left = ref(0)
const top = ref(0)
const positionX = ref(0)
const positionY = ref(0)
watch([elementX, elementY, isOutside], () => {
console.log('xy变化了')
// 如果鼠标没有移入到盒子里面 直接不执行后面的逻辑
if (isOutside.value) return
console.log('后续逻辑执行了')
// 有效范围内控制滑块距离
// 横向
if (elementX.value > 100 && elementX.value < 300) {
left.value = elementX.value - 100
}
// 纵向
if (elementY.value > 100 && elementY.value < 300) {
top.value = elementY.value - 100
}
// 处理边界
if (elementX.value > 300) { left.value = 200 }
if (elementX.value < 100) { left.value = 0 }
if (elementY.value > 300) { top.value = 200 }
if (elementY.value < 100) { top.value = 0 }
// 控制大图的显示
positionX.value = -left.value * 2
positionY.value = -top.value * 2
})

放大镜效果实现 - 大图效果实现
效果:为实现放大效果,大图的宽高是小图的两倍
思路:大图的移动方向和滑块移动方向相反,且数值为2倍
放大镜效果实现 - 鼠标移入控制显隐
思路:鼠标移入盒子(isOutside),滑块和大图才显示(v-show)
组件props适配
组件中的图片列表不能写死,需要通过props参数把接口数据传入
defineProps({
imageList: {
type: Array,
default: () => []
}
})
总结
SKU的概念
存货单位,也翻译为库存单元,是一个会计学名词,定义为库存管理中最小可用单元
,例如纺织品中一个SKU通常表示规格,颜色,款式,而在连锁零售门店中优势称单品为一个SKU
SKU组件的作用:产出当前用户选择的商品规格
,为加入购物车操作提供数据信息
SKU组件使用
问:在实际工作中,经常会遇到别人写好的组件,熟悉一个三方组件,首先重点看什么?
答:props和emit,props决定了当前组件接收什么数据,emit决定了会产出什么数据
为什么要优化
背景:components目录下有可能还会有很多其他通用型组件,有可能在多个业务模块中共享,所有统一进行全局组件注册比较好
// 把components中的所组件都进行全局化注册
// 通过插件的方式
import ImageView from './ImageView/index.vue'
import Sku from './XtxSku/index.vue'
export const componentPlugin = {
install (app) {
// app.component('组件名字',组件配置对象)
app.component('XtxImageView', ImageView)
app.component('XtxSku', Sku)
}
}
// 引入全局组件插件
import { componentPlugin } from '@/components'
app.use(componentPlugin)
