2. 配置路由
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
// path和component对应关系的位置
routes: [
{
path: '/',
component: Layout,
children: [
{
path: '',
component: Home
},
{
path: 'category/:id',
component: Category
},
{
path: 'category/sub/:id',
component: SubCategory
},
{
path: 'detail/:id',
component: Detail
}
]
},
{
path: '/login',
component: Login
}
],
// 路由滚动行为定制
scrollBehavior () {
return {
top: 0
}
}
})
3. 绑定模版测试跳转
<RouterLink :to="`/detail/${item.id}`">
<img :src="item.picture" alt="" />
<p class="name">{{ item.name }}</p>
<p class="price">¥{{ item.price }}</p>
</RouterLink>
渲染基础数据
1. 封装接口
import request from '@/utils/http'
export const getDetail = (id) => {
return request({
url: '/goods',
params: {
id
}
})
}
2. 获取数据渲染模版
<script setup>
import { getDetail } from '@/apis/detail'
import { onMounted, ref } from 'vue'
import { useRoute } from 'vue-router'
const goods = ref({})
const route = useRoute()
const getGoods = async () => {
const res = await getDetail(route.params.id)
goods.value = res.result
}
onMounted(() => getGoods())
</script>
<template>
<div class="xtx-goods-page">
<div class="container" v-if="goods.details">
<div class="bread-container">
<el-breadcrumb separator=">">
<el-breadcrumb-item :to="{ path: '/' }">首页</el-breadcrumb-item>
<!--
错误原因：goods一开始{} {}.categories -> undefined -> undefined[1]
1. 可选链的语法?.
2. v-if手动控制渲染时机 保证只有数据存在才渲染
-->
<el-breadcrumb-item :to="{ path: `/category/${goods.categories[1].id}` }">{{ goods.categories[1].name }}
</el-breadcrumb-item>
<el-breadcrumb-item :to="{ path: `/category/sub/${goods.categories[0].id}` }">{{
goods.categories[0].name
}}

热榜区域
1. 渲染基础热榜数据
1- 准备模版
<script setup>
</script>
<template>
<div class="goods-hot">
<h3>周日榜单</h3>
<!-- 商品区块 -->
<RouterLink to="/" class="goods-item" v-for="item in 3" :key="item.id">
<img :src="item.picture" alt="" />
<p class="name ellipsis">一双男鞋</p>
<p class="desc ellipsis">一双好穿的男鞋</p>
<p class="price">¥200.00</p>
</RouterLink>
</div>
</template>
<style scoped lang="scss">
.goods-hot {
h3 {
height: 70px;
background: $helpColor;
color: #fff;
font-size: 18px;
line-height: 70px;
padding-left: 25px;
margin-bottom: 10px;
font-weight: normal;
}
.goods-item {
display: block;
padding: 20px 30px;
text-align: center;
background: #fff;
img {
width: 160px;
height: 160px;
}
p {
padding-top: 10px;
}
.name {
font-size: 16px;
}
.desc {
color: #999;
height: 29px;
}
.price {
color: $priceColor;
font-size: 20px;
}
}
}
</style>
2- 封装接口
/**
* 获取热榜商品
* @param {Number} id - 商品id
* @param {Number} type - 1代表24小时热销榜 2代表周热销榜
* @param {Number} limit - 获取个数
*/
export const fetchHotGoodsAPI = ({ id, type, limit = 3 }) => {
return request({
url:'/goods/hot',
params:{
id,
type,
limit
}
})
}
3- 获取基础数据渲染模版
<script setup>
import { ref } from 'vue'
import { getHotGoodsAPI } from '@/apis/detail'
import { useRoute } from 'vue-router'
const goodList = ref([])
const route = useRoute()
const getHotList = async () => {
const res = await getHotGoodsAPI({
id: route.params.id,
type: 1
})
goodList.value = res.result
}
getHotList()
</script>
<template>
<div class="goods-hot">
<h3> 24小时热榜 </h3>
<!-- 商品区块 -->
<RouterLink :to="`/detail/${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>
</template>
2. 适配热榜类型
1- 设计props参数type
// 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" />
3. 适配热榜title
const TITLEMAP = {
1: '24小时热榜',
2: '周热榜',
}
const title = computed(() => TITLEMAP[props.type])
<h3>{{ title }}</h3>
图片预览组件封装
1. 小图切换大图显示
1- 准备模版
<script setup>
// 图片列表
const imageList = [
"

]
</script>
<template>
<div class="goods-image">
<!-- 左侧大图-->
<div class="middle" ref="target">

<!-- 蒙层小滑块 -->
<div class="layer" :style="{ left: `0px`, top: `0px` }"></div>
</div>
<!-- 小图列表 -->
<ul class="small">

</ul>
<!-- 放大镜大图 -->
<div class="large" :style="[

backgroundPositionX: `0px`,
backgroundPositionY: `0px`,
},
]" v-show="false"></div>
</div>
</template>
<style scoped lang="scss">
.goods-image {

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 -->

:key="i"
@mouseenter="mouseEnterFn(i)"
:class="{ active: i === curIndex }">
<img :src="img" alt="" />
</li>
</ul>
</div>
</template>
2. 放大镜效果实现
<script setup>
import { ref, watch } from 'vue'
import { useMouseInElement } from '@vueuse/core'
// 图片列表
const imageList = [
"

]
// 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

SKU组件熟悉
全局组件统一插件化
1. 插件化开发
// 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)
}
}
2. 插件注册
// 引入全局组件插件
import { componentPlugin } from '@/components'
app.use(componentPlugin)
