如何在Vue中实现图片预览功能

npm install vue-awesome-swiper --save

import Vue from 'vue'
import App from './App.vue'
import Swiper from 'vue-awesome-swiper'
// import Swiper styles
import 'swiper/dist/css/swiper.css'
Vue.use(Swiper)

new Vue({
  el: '#app',
  render: h => h(App),
})

<template>
  <div class="container">
    <swiper :options="swiperOption">
      <swiper-slide
        v-for="(item, index) in imgList"
        :key="index"
      >
        <img :src="item.url" @click="previewImage(item.url)" />
      </swiper-slide>
      <div class="swiper-pagination" slot="pagination"></div>
    </swiper>
  </div>
</template>

<script>
export default {
  data() {
    return {
      imgList: [
        {
          url:
            'https://raw.githubusercontent.com/surmon-china/vue-awesome-swiper/HEAD/swiper-demo/static/images/1.png',
        },
        {
          url:
            'https://raw.githubusercontent.com/surmon-china/vue-awesome-swiper/HEAD/swiper-demo/static/images/2.png',
        },
        {
          url:
            'https://raw.githubusercontent.com/surmon-china/vue-awesome-swiper/HEAD/swiper-demo/static/images/3.png',
        },
      ],
      swiperOption: {
        pagination: '.swiper-pagination',
        paginationClickable: true,
        loop: true,
      },
    }
  },
  methods: {
    previewImage(url) {
      this.$modal.show('preview', {
        src: url, // 图片链接，必填
      })
    },
  },
}
</script>
