效果

请添加图片描述

具体代码实现

创建商品图片展示的vue页面:ProductPicShow.vue

<script lang="ts" setup>
import { ref, computed } from 'vue'
import { useMouseInElement } from '@vueuse/core'

defineProps<{
  images: string[]
}>()
// 当前显示的图片索引
let active = ref(0)
// ref 获取 DOM 元素的位置
const target = ref(null)
// isisOutside为 true 的时候代表鼠标未进入目标元素,为 false 时代表鼠标进入目标元素
const { elementX, elementY, isOutside } = useMouseInElement(target)
// 遮罩半透明图在商品大图中的坐标位置
const position = computed(() => {
  let x = elementX.value - 100
  let y = elementY.value - 100
  if (x <= 0) x = 0
  if (x >= 200) x = 200
  if (y <= 0) y = 0
  if (y >= 200) y = 200
  return { x, y }
})
</script>
<template>
  <div class="product-image">
    <!-- 放大镜的大盒子 -->
    <div
        class="large"
        :style="[
        {
          backgroundImage: `url(${images[active]})`,
          backgroundPosition: `-${position.x * 3}px -${position.y * 3}px`
        }
      ]"
        v-show="!isOutside"
    ></div>
    <div ref="target" class="middle">
      <img :src="https://www.atool.online/article/images[active]" alt="" />
      <!-- 鼠标移动时的遮罩层 -->
      <div
          class="layer"
          v-show="!isOutside"
          :style="{ left: `${position.x}px`, top: `${position.y}px` }"
      ></div>
    </div>
    <ul class="small">
      <li
          v-for="(item, index) in images"
          :key="item"
          :class="{ active: index === active }"
          @mouseenter="active = index"
      >
        <img :src="https://www.atool.online/article/item" alt="" />
      </li>
    </ul>
  </div>
</template>

<style scoped lang="less">
.product-image {
  width: 480px;
  height: 400px;
  position: relative;
  display: flex;
  z-index: 500;
  .large {
    position: absolute;
    top: 0;
    left: 412px;
    width: 600px;
    height: 600px;
    box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
    background-repeat: no-repeat;
    background-size: 200% 200%;
    background-color: #f8f8f8;
  }
  .middle {
    width: 400px;
    height: 400px;
    background: #f5f5f5;
    position: relative;
    cursor: move;
    .layer {
      width: 200px;
      height: 200px;
      background: rgba(0, 0, 0, 0.2);
      left: 0;
      top: 0;
      position: absolute;
    }
  }
  .small {
    width: 80px;
    li {
      width: 68px;
      height: 68px;
      margin-left: 12px;
      margin-bottom: 15px;
      cursor: pointer;
      &:hover,
      &.active {
        border: 2px solid #27BA9B;
      }
    }
  }
}
</style>

使用:Product.vue

<template>
  <div class="product-info">
    <div class="media">
      <ProductPicShow :images="slidePics"/>
    </div>
  </div>
</template>
<script setup lang="ts">
import ProductPicShow from "@/views/product/components/ProductPicShow.vue"
</script>
<style scoped lang="less">
.product-info {
  min-height: 600px;
  background: #fff;
  display: flex;

  .media {
    width: 580px;
    height: 600px;
    padding: 30px 50px;
  }
}
</style>
