1、第一种写法

 {
  "v-viewer": "^3.0.13",
  "viewerjs": "^1.11.6"
 }

<template>
  <div>
    <viewer :images="imageUrls">
      <img v-for="(image, index) in imageUrls" style="width: 300px;" :src="image" :key="index" />
    </viewer>
  </div>
</template>

<script setup>
  import { onMounted, ref, nextTick } from 'vue';
  import 'viewerjs/dist/viewer.css'
  import { component as Viewer } from "v-viewer"

  let imageUrls = ref([
    'https://fuss10.elemecdn.com/a/3f/3302e58f9a181d2509f3dc0fa68b0jpeg.jpeg',
    'https://fuss10.elemecdn.com/1/34/19aa98b1fcb2781c4fba33d850549jpeg.jpeg',
    'https://fuss10.elemecdn.com/0/6f/e35ff375812e6b0020b6b4e8f9583jpeg.jpeg',
    'https://fuss10.elemecdn.com/9/bb/e27858e973f5d7d3904835f46abbdjpeg.jpeg',
    'https://fuss10.elemecdn.com/d/e6/c4d93a3805b3ce3f323f7974e6f78jpeg.jpeg',
    'https://fuss10.elemecdn.com/3/28/bbf893f792f03a54408b3b7a7ebf0jpeg.jpeg',
    'https://fuss10.elemecdn.com/2/11/6535bcfb26e4c79b48ddde44f4b6fjpeg.jpeg',
  ])

</script>

第二种写法（推荐）

<template>
  <div ref="image">
    <img
        :src="item"
        alt=""
        class="image"
        @click="getOnclick"
        :data-original="`${item}`"
        v-for="item in imageList"
    />
  </div>
</template>

<script setup>
import Viewer from "viewerjs";
import "viewerjs/dist/viewer.css";
import {reactive, ref, onMounted, nextTick} from "vue";

let imageList = reactive([
  "https://cdn.uviewui.com/uview/swiper/1.jpg",
  "https://cdn.uviewui.com/uview/swiper/swiper1.png",
  "https://cdn.uviewui.com/uview/swiper/swiper2.png",
  "https://cdn.uviewui.com/uview/swiper/swiper3.png",
]);
const image = ref(null);
const getOnclick = () => {
  const viewer = new Viewer(image.value, {
    // 相关配置项,详情见下面
  });
};
</script>

<style scoped>
.image {
  width: 400px;
  height: 200px;
  cursor: pointer;
  display: block;
  margin-top: 20px;
}
</style>
