1. 问题

离开当前页面后样式会重置，用户体验相当不好，注意看下图在跳转页面时swiper样式的变化

错误.gif

2. 原因：

<swiper ref="mySwiper" :options="swiperOption">
  <swiper-slide v-for="(item, index) in cardList" :key="index">
    <img :src="item.imgUrl" alt />
  </swiper-slide>
</swiper>

import { Swiper, SwiperSlide } from "vue-awesome-swiper";
import "swiper/swiper-bundle.css";

export default {
  components: {
    Swiper,
    SwiperSlide
  },
  computed: {
    mySwiper() {
      return this.$refs.mySwiper.$swiper;
    }
  },
  data() {
    return {
      swiperOption: {
        direction: "horizontal",
        initialSlide: 1,
        observeParents: true,
        observer: true,
        slidesPerView: "auto",
        centeredSlides: true,
        spaceBetween: 20,
      }
    };
  }
};
</script>

3. 方案：

<div class="swiper-container">
  <div class="swiper-wrapper">
    <div class="swiper-slide" v-for="(item, index) in cardList" :key="index">
      <img :src="item.imgUrl" alt />
    </div>
  </div>
</div>

import Swiper from "swiper/swiper-bundle.min.js";
import "swiper/swiper-bundle.min.css";

export default {
  data() {
    mySwiper: null
  }，
  mounted() {
    this.$nextTick(() => {
      this.mySwiper = new Swiper(".swiper-container", {
        direction: "horizontal",
        initialSlide: 1,
        slidesPerView: "auto",
        centeredSlides: true,
        spaceBetween: 20
      });
    });
  }
};
</script>

4. 修改后的效果：

请看效果，对比上面的那个图，是不是就好多了呢
