步骤2：配置路由

重构router/index.js

import Detail from '@/views/Detail/index.vue'
...
        ,
        {
          path: 'detail/:id',
          component: Detail
        }

步骤3：绑定模版测试跳转

重构HomeNew.vue和HomeHot

<RouterLink :to="`/detail/${item.id}`">
  <img :src="item.picture" alt="" />
  <p class="name">{{ item.name }}</p>
  <p class="price">&yen;{{ item.price }}</p>
</RouterLink>

重构GoodsItem.vue

<RouterLink :to="`/detail/${good.id}`" class="goods-item">
  <img :src="good.picture" alt="" />
  <p class="name ellipsis">{{ good.name }}</p>
  <p class="desc ellipsis">{{ good.desc }}</p>
  <p class="price">&yen;{{ good.price }}</p>
</RouterLink>

6-2 实现面包屑导航

步骤1：创建API接口

创建apis/detail.js

import http from "@/utils/http";

/**
 * @description: 根据id获得商品详情
 * @param {*} id 分类id
 * @return {*}
 */
export function getDetail(id){
    return http.get('/goods',{params:{id}});
}

步骤2： 获取数据渲染模版

重构Detail/index.vue

script代码

<script setup>
import { getDetail } from '@/apis/detail'
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代码

<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 }}
          </el-breadcrumb-item>
          <el-breadcrumb-item>{{goods.desc}}</el-breadcrumb-item>
        </el-breadcrumb>
      </div>

解决方式1：可选链的语法?.

<template>
  <div class="xtx-goods-page">
    <div class="container">
      <div class="bread-container">
        <el-breadcrumb separator=">">
          <el-breadcrumb-item :to="{ path: '/' }">首页</el-breadcrumb-item>
          <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}}
          </el-breadcrumb-item>
          <el-breadcrumb-item>{{goods.desc}}</el-breadcrumb-item>
        </el-breadcrumb>
      </div>

解决方式2：v-if

<template>
  <div class="xtx-goods-page">
    <div class="container" v-if="goods.categories">
      <div class="bread-container" >
        <el-breadcrumb separator=">">
          <el-breadcrumb-item :to="{ path: '/' }">首页</el-breadcrumb-item>
          <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}}
          </el-breadcrumb-item>
          <el-breadcrumb-item>抓绒保暖，毛毛虫子儿童运动鞋</el-breadcrumb-item>
        </el-breadcrumb>
      </div>

                  <!-- 图片 -->
                  <img v-for="img in goods.details.pictures" :src="img" :key="img" alt="">

                </div>
              </div>
            </div>
            <!-- 24热榜+专题推荐 -->
            <div class="goods-aside">

            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

图片可以优化懒加载

<img v-for="img in goods.details.pictures" v-img-lazy="img" :key="img">

6-4 实现热榜组件

步骤1：创建热榜组件

1:创建components/DetailHot.vue

<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">&yen;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 getHotGoodsAPI = ({ id, type, limit = 3 }) => {
    return http.get('/goods/hot',{params:{
            id,
            type,
            limit
        }});
}

3- 获取基础数据渲染模版

<script setup>
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
}
onMounted(()=>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">&yen;{{ item.price }}</p>
    </RouterLink>
  </div>
</template>

4- 重构Detal/index.vue

<!-- 24热榜+专题推荐 -->
            <div class="goods-aside">
              <DetailHot />
            </div>

步骤2：适配热榜类型与title

重构页面script

<script setup>
import { getHotGoodsAPI } from '@/apis/detail'
import { useRoute } from 'vue-router'

// 设计props参数 适配不同的title和数据
const props = defineProps({
  hotType: {
    type: Number
  }
})

// 适配title 1 - 24小时热榜  2-周热榜
const TYPEMAP = {
  1: '24小时热榜',
  2: '周热榜'
}
    
const title = computed(() => {
  return TYPEMAP[props.hotType]
})

const goodList = ref([])
const route = useRoute()
const getHotList = async () => {
  const res = await getHotGoodsAPI({
    id: route.params.id,
    type: props.hotType
  })
  goodList.value = res.result
}
onMounted(()=>getHotList())

</script>

2-重构页面-template

<template>
  <div class="goods-hot">
    <h3>{{ title }}</h3>

3- 重构Detal/index.vue

<!-- 24热榜+专题推荐 -->
            <div class="goods-aside">
              <DetailHot :hot-type="1"/>
              <DetailHot :hot-type="2"/>

            </div>

6-5 实现图片预览组件

##6-5-1 实现小图切换大图

步骤1：创建图片预览组件

创建components/ImageView/index.vue

1- 准备模版

<script setup>
// 图片列表
const imageList = [
  "https://yanxuan-item.nosdn.127.net/d917c92e663c5ed0bb577c7ded73e4ec.png",

</script>


<template>
  <div class="goods-image">
    <!-- 左侧大图-->
    <div class="middle">
      <img :src="imageList[0]" alt="" />
      <!-- 蒙层小滑块 -->
      <div class="layer" :style="{ left: `0px`, top: `0px` }"></div>
    </div>
    <!-- 小图列表 -->
    <ul class="small">
      <li v-for="(img, i) in imageList" :key="i">
        <img :src="img" alt="" />
      </li>
    </ul>
    <!-- 放大镜大图 -->
    <div class="large" :style="[
      {
        backgroundImage: `url(${imageList[0]})`,
        backgroundPositionX: `0px`,
        backgroundPositionY: `0px`,
      },
    ]" v-show="false"></div>
  </div>
</template>

<style scoped lang="scss">
.goods-image {
  width: 480px;
  height: 400px;
  position: relative;
  display: flex;

  .middle {
    width: 400px;

    z-index: 500;
    box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
    background-repeat: no-repeat;
    // 背景图:盒子的大小 = 2:1  将来控制背景图的移动来实现放大的效果查看 background-position
    background-size: 800px 800px;
    background-color: #f8f8f8;
  }

  .layer {
    width: 200px;
    height: 200px;
    background: rgba(0, 0, 0, 0.2);
    // 绝对定位 然后跟随咱们鼠标控制left和top属性就可以让滑块移动起来
    left: 0;
    top: 0;
    position: absolute;
  }

  .small {
    width: 80px;

    li {

      &:hover,
      &.active {
        border: 2px solid $xtxColor;
      }
    }
  }
}
</style>

2-重构Detail/index.vue

import ImageView from "@/components/ImageView/index.vue"
...
<!-- 图片预览区 -->
<ImageView/>

步骤2：实现小图切大图效果

<script setup>
import {ref} from 'vue'
// 图片列表
const imageList = [
  "https://yanxuan-item.nosdn.127.net/d917c92e663c5ed0bb577c7ded73e4ec.png",

  "https://yanxuan-item.nosdn.127.net/f881cfe7de9a576aaeea6ee0d1d24823.jpg"
]
// 1.小图切换大图显示
const activeIndex = ref(0)

const enterHandler = (i) => {
  //console.log(i)
  activeIndex.value = i
}

</script>


<template>
  <div class="goods-image">
    <!-- 左侧大图-->
    <div class="middle" ref="target">
      <img :src="imageList[activeIndex]" alt="" />
      <!-- 蒙层小滑块 -->
      <div class="layer" :style="{ left: `0px`, top: `0px` }"></div>
    </div>

          :key="i" @mouseenter="enterHandler(i)"
          :class="{ active:i === activeIndex }"
      >
        <img :src="img" alt="" />
      </li>
    </ul>

6-5-2 实现放大镜效果

步骤1：实现滑块移动

<script>
    ...
// 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)

watch([elementX, elementY, isOutside], () => {

  // 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

  // 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 }

})

</script>

重构template

<template>
  {{elementX}} {{elementY}} {{isOutside}}
  <div class="goods-image">
    <!-- 左侧大图-->
    <div class="middle" ref="target">
      <img :src="imageList[activeIndex]" alt="" />
      <!-- 蒙层小滑块 -->
      <div class="layer" :style="{ left: `${left}px`, top: `${top}px` }"
           v-show="!isOutside"></div>
    </div>

步骤2：实现放大镜效果

// 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], () => {

  // 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

  // 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

})

重构template

    <!-- 放大镜大图 -->
    <div class="large" :style="[
      {
        backgroundImage: `url(${imageList[activeIndex]})`,
        backgroundPositionX: `${positionX}px`,
        backgroundPositionY: `${positionY}px`,
      },
    ]" v-show="!isOutside"></div>

6-5-3 实现图片组件数据封装

重构script

// 图片列表
defineProps({
  imageList:{
    type:Array,
    default:()=>[]
  }
})
// const imageList = [
//   "https://yanxuan-item.nosdn.127.net/d917c92e663c5ed0bb577c7ded73e4ec.png",
//   "https://yanxuan-item.nosdn.127.net/e801b9572f0b0c02a52952b01adab967.jpg",

//   "https://yanxuan-item.nosdn.127.net/f881cfe7de9a576aaeea6ee0d1d24823.jpg"
// ]

重构Detail/index.vue

<!-- 图片预览区 -->
<ImageView :image-list="goods.mainPictures"/>

6-6 第三方SKU组件应用

第三方组件：

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

1691041214641

重构Detail/index.vue

import Sku from "@/components/sku/index.vue"
...

//sku组件触发方法
const skuChange = (sku)=>{
  console.log(sku)
}
</script>
...
<!-- sku组件 -->
<Sku :goods="goods" @change="skuChange"/>

6-7 全局组件插件化配置

步骤1： 插件化开发

创建components/index.js

// 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 './sku/index.vue'
export const componentPlugin = {
    install (app) {
        // app.component('组件名字'，组件配置对象)
        app.component('ImageView', ImageView)
        app.component('Sku', Sku)
    }
}

步骤2：插件注册与调用

重构main.js

// 引入全局组件插件
import { componentPlugin } from '@/components'

app.use(componentPlugin)

重构Detail/index.vue

<!-- 图片预览区 -->
<ImageView :image-list="goods.mainPictures"/>
<!-- sku组件 -->
<Sku :goods="goods" @change="skuChange"/>
