使用

<template>
  <div>
    <van-image-preview :images="images" />
    <!-- 也支持大驼峰命名 -->
  </div>
</template>

<script>
import { ImagePreview } from 'vant';
export default {
  components: {
    [ImagePreview.name]: ImagePreview
  },

  data() {
    return {
      images: [
        'https://xxx.jpeg',
        'https://xxx.mp4',
