在vue中使用swiper

<template>
  <div class="main">
    <!-- .swiper-container  -->
    <div class="wrap">
      <img class="bgImg" src="../../../../assets/images/fffbg.png" alt />
      <swiper :options="swiperOption" ref="mySwiper">
        <swiper-slide v-for="(item,index) in swiperList " :key="index">
          <div class="img1">
            <img :src="item.img" alt />
          </div>
        </swiper-slide>
      </swiper>
    </div>
  </div>
</template>
<script>
export default {
  name: "swiperList",
  data() {
    return {
      activeId: 0, ///   当前轮播图的序号
      swiperOption: {
        slidesPerView: 3,
        spaceBetween: 20,
        centeredSlides: true,
        loop: false,
        initialSlide :1, /// 默认页

        pagination: {
          // el: ".swiper-pagination",
          // clickable: true
        },
        on: {
          
          // 当轮播时触发
          slideChange: e => {
            let swiper = this.$refs.mySwiper.swiper;
            let i = swiper.activeIndex;
            this.activeId = i;
            console.log(i); ///  轮播的序号从 0 开始
            this.$emit("handleChangeId", i);
          }
        }
      }
    };
  },
  props: {
