在body最后添加如下js

<script>
          var swiper = new Swiper('.swiper-container', {
              slidesPerView: 3,
              spaceBetween: 30,
              slidesPerGroup: 3,
              loop: true,
              loopFillGroupWithBlank: true,
              autoplay: true,
              pagination: {
                  el: '.swiper-pagination',
                  clickable: true
              },
              navigation: {
                  nextEl: '.swiper-button-next',
                  prevEl: '.swiper-button-prev',
              },
              // 自动切换
              autoplay: {
                  // 切换时间
                  delay: 3000,
                  // 是否无限播放
                  stopOnLastSlide: false,
                  // 是否受干扰
                  disableOnInteraction: true,
              }
          });
      </script>
