今天看到同事在写轮播图，由于是jq的写法，我没有过多参与，我只写vue的部分。。。虽然语言不一样，但是用法还是要会的。下面介绍通过swiper组件来实现轮播效果。

解决步骤1：安装swiper

npm install swiper@5.4.5
我这边安装的版本是5.4.5

解决步骤2：在指定页面中局部注册

import Swiper from 'swiper'; // 注意引入的是Swiper
import 'swiper/css/swiper.min.css'; // 注意这里的引入

解决步骤3：多图轮播效果

3.1html代码

 <div class="banshi">
      <div class="swiper-container">
        <div class="swiper-wrapper">
          <div
            v-for="item in swiperList"
            :key="item.id"
            class="swiper-slide"
            :style="`background-image:url(${item.imgUrl})`"
          >
            <h3>{{ item.title }}</h3>
            <el-button>立即办理</el-button>
          </div>
        </div>
        <div class="swiper-pagination"></div>
        <div class="swiper-button-next"></div>
        <div class="swiper-button-prev"></div>
      </div>
    </div>

3.2 js代码

swiper: null,
swiperList: [
 {
   id: 1,
   title: '采集国家二级保护野生植物审批',
   imgUrl:
     'https://img0.baidu.com/it/u=2639758887,1655012884&fm=253&fmt=auto&app=138&f=PNG?w=632&h=500',
 },
 {
   id: 2,
   title: '农村危房改造',
   imgUrl:
     'https://img0.baidu.com/it/u=2639758887,1655012884&fm=253&fmt=auto&app=138&f=PNG?w=632&h=500',
 },
 {
   id: 3,
   title: '农村危房改造',
   imgUrl:
     'https://img0.baidu.com/it/u=2639758887,1655012884&fm=253&fmt=auto&app=138&f=PNG?w=632&h=500',
 },
 {
   id: 4,
   title: '农村危房改造',
   imgUrl:
     'https://img0.baidu.com/it/u=2639758887,1655012884&fm=253&fmt=auto&app=138&f=PNG?w=632&h=500',
 },
],

3.3 methods方法

getSwiper() {
   this.swiper = new Swiper('.swiper-container', {
     loop: true, // 无缝
        autoplay: { //自动开始
            delay: 3000, //时间间隔
            disableOnInteraction: false, //*手动操作轮播图后不会暂停*
        },
        paginationClickable: true,
        slidesPerView: 4, // 一组三个
        spaceBetween: 30, // 间隔
        // 如果需要前进后退按钮
        navigation: {
            nextEl: '.swiper-button-next',
            prevEl: '.swiper-button-prev',
        },
        // 窗口变化,重新init,针对F11全屏和放大缩小,必须加
        observer: true,
        observeParents: true,
        // 如果需要分页器
        pagination: {
            el: '.swiper-pagination',
            clickable: true, // 分页器可以点击
        }, 
    });
 },

此方法要在mounted中使用：

mounted() {
  this.getSwiper();
},

3.4 css样式

<style lang="less">
.banshi {
  width: 1200px;
  margin: 0 auto;
  padding: 70px 0;
  .swiper-slide {
    position: relative;
    height: 328px;
    width: 264px;
    padding: 36px 22px;
    background-repeat: no-repeat;
    background-size: contain;
    background-color: #f7f8fa;
    .el-button {
      z-index: 2;
    }
  }
}
</style>

4.2 methods方法

getSwiper() {
  var swiper = new Swiper('.swiper-container', {
    slidesPerView: 1.5, //设置slider容器能够同时显示的slides数量(carousel模式)。
    spaceBetween: -180, //在slide之间设置距离（单位px）。
    centeredSlides: true, //设置活动块居中
    loop: true,
    pagination: {
