写法一

<template>
  <div
    class="demo-img"
    v-for="item in demoOption"
    :key="item.code"
    :style="`background-image: url(${getImageUrl(`../assets/imge/${item.img}.jpeg`)})`"
  ></div>
</template>

<script lang="ts" setup>
import { reactive } from 'vue';
const demoOption = reactive([
  { label: '图一', code: 'one', img: 'one' },
  { label: '图二', code: 'too', img: 'too' }
])
const getImageUrl = (name:string) => {
  return new URL(`${name}`, import.meta.url).href
}
</script>
<style lang="scss" scoped>
.demo-img{
  width: 400px;
  height: 200px;
  background-position: right bottom;
  background-repeat: no-repeat;
  background-size: 63%;
}
</style>
