Swiper js的slider

Question

这是一个自动播放幻灯片，我想添加模糊效果的图像，一旦通过和即将到来的图像，但不是第一个图像。我怎么能做到这一点？我还想通过使用javascript.For示例来定位动态样式元素，我想定位z索引元素

​

var swiper = new Swiper(".mySwiper", {
  effect: "coverflow",
  loop: true,
  grabCursor: true,
  centeredSlides: true,
  slidesPerView: "auto",
  coverflowEffect: {
    rotate: 20,
    stretch: 0,
    depth: 700,
    modifier: 1,
    slideShadows: true,
  },
  pagination: {
    el: ".swiper-pagination",
  },
  autoplay: {
    delay: 1000,
    disableOnInteraction: false,
  },
});

html,
body {
  position: relative;
  height: 100%;
  ## ---------- 1. List item ##
}

body {
  background: #eee;
  font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
  font-size: 14px;
  color: #000;
  margin: 0;
  padding: 0;
}

.swiper-container {
  width: 100%;
  padding-top: 50px;
  padding-bottom: 50px;
}

.swiper-slide {
  background-position: center;
  background-size: cover;
  width: 300px;
  height: 300px;
}

.swiper-slide img {
  display: block;
  width: 100%;
  height: 100%;
}

Answer 1

您可以在所有幻灯片上添加filter: blur(3px) (例如)，然后将活动幻灯片设置为filter: unset；

.swiper-slide { filter: blur(3px); }
.swiper-slide-active { filter: unset; }

您可以使用JS将活动幻灯片作为目标，例如使用document.querySelector('.swiper-slide-active').classList.add('my-z-index-class')

(您需要添加一个名为.my-z-index-class的CSS类，这个示例才能正常工作)。
