使用Vue + ts封装一个轮播插件

<!-- vue 实现轮播图 -->
<template>
 <div id="swiperDIV" : @mouseover="suspend" @mouseout="autoPlay" @blur="suspend"
  @focus="autoPlay">
  <!-- 淡入淡出效果 -->
  <transition-group tag="ul" class="img-list" :name="animation">
   <li v-for="(item, index) in bannerList" :key="item.id" v-show="curIndex === index">
    <img :src="item[nameField]">
   </li>
  </transition-group>
  <!-- 操作按钮部分(底部导航器) -->
  <ul class="option-list" v-if="showPagination">
   <li class="option-list-item" :class="curIndex === index &#63; 'cur-option-style':''"
    v-for="(item, index) in bannerList" :key="item.id" @click="jump(item, index)"></li>
  </ul>

  <!-- 左侧右侧切换按钮 -->
  <template v-if="showBtn">
   <div class="common-btn-space pre-btn-space">
    <span class="common-btn-span pre-btn-span"></span>
   </div>
   <div class="common-btn-space next-btn-space">
    <span class="common-btn-span next-btn-span"></span>
   </div>
  </template>
 </div>
