状态管理+方法

stores/imgSeeStore.js

import { defineStore } from 'pinia'
export const imgSeeStore = defineStore('imgSeeStore', {
    state: () => ({
        showImgSee: false,
        ImgUrl: '',
    }),
    getters: {
    },
    actions: {
        openImgShow(url) {
            this.ImgUrl = url
            this.showImgSee = true
        },
        resetSeeImg() {
            this.ImgUrl = ''
            this.showImgSee = false
        }
    }
})

封装的组件

<template>
  <img ref="el" :src="ImgUrl" />
</template>

<script setup>javascript">
import "viewerjs/dist/viewer.css";
import Viewer from "viewerjs";
import { nextTick, onMounted, ref } from "vue";
import { storeToRefs } from "pinia";
import { globalStateStore } from "src/stores/globalState";

const useGlobalStateStore = globalStateStore(),
  { ImgUrl } = storeToRefs(useGlobalStateStore),
  { resetSeeImg } = useGlobalStateStore;

const el = ref();
onMounted(async () => {
  await nextTick();
  //   图片查看器关闭事件
  el.value.addEventListener("hide", () => resetSeeImg());

  new Viewer(el.value, {
    navbar: false,
    title: false,
  }).show();
});
</script>

使用

TestVue.vue

<template>
  <!-- 这个是要点击查看的图片 -->
   <img 
       style="max-width: 200px" 
       :src="img"
       @click="openImgShow(img)"
     />

<img-see v-if="showImgSee" />
</template>

<script setup>javascript">
import { ref} from "vue";
import { storeToRefs } from "pinia";
import ImgSee from "src/components/ImgSee.vue";
import { imgSeeStore} from "src/stores/imgSeeStore";  

const img = ref('/public/test.jpg')
const useImgSeeStore= imgSeeStore(),
  { showImgSee } = storeToRefs(useImgSeeStore),
  { openImgShow } = useImgSeeStore;
</script>
