基于elementUI实现图片预览组件的示例代码

//引入了src下的vue组件文件
import starPicList from './src/star-pic-list';

/* istanbul ignore next */
starPicList.install = function(Vue) {
  //starPicList.name这就是后面可以使用的组件的名字(star-pic-list.vue文件里面定义的name)，install是默认的一个方法
  Vue.component(starPicList.name, starPicList);
};

export default starPicList;

<!--图片列表形式，点击查看图片列表，点击显示上（下）一张-->
<template v-slot="scope">
  <star-pic-list :data="scope.row.pic" :max-show="2"/>
</template>

<template>
  <div id="star-pic-vue">
    <template v-if="data">
      <img v-for="item in images"
         :src="item"
         id="contract_url"

      <template v-if="isDialogShow">
