js实现带动画效果的html轮播图

好的，下面是一个使用 JavaScript 实现带动画效果的 HTML 轮播图：

HTML：

<div class="slider">
  <img class="slide active" src="image1.jpg">
  <img class="slide" src="image2.jpg">
  <img class="slide" src="image3.jpg">
  <img class="slide" src="image4.jpg">
  <div class="prev"></div>
  <div class="next"></div>
</div>

CSS：

.slider {
  position: relative;
  width: 100%;
  height: 400px;
  overflow: hidden;
}

.slide {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  opacity: 0;
  transition: opacity 1s ease-in-out;
}

.slide.active {
  opacity: 1;
}

.prev, .next {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  width: 30px;
  height: 30px;
  background-color: #000;
  opacity: 0.5;
  cursor: pointer;
}

.prev:hover, .next:hover {
  opacity: 1;
}

.prev {
  left: 20px;
}

.next {
  right: 20px;
}

JavaScript：

let slides = document.querySelectorAll('.slide');
let currentSlide = 0;
let slideInterval = setInterval(nextSlide, 3000);

function nextSlide() {
  let prevSlide = currentSlide;
  currentSlide = (currentSlide + 1) % slides.length;
  slides[prevSlide].classList.remove('active');
  slides[currentSlide].classList.add('active');
  slides[currentSlide].style.animation = 'slideInRight 1s forwards';
  slides[prevSlide].style.animation = 'slideOutLeft 1s forwards';
}

function prevSlide() {
  let prevSlide = currentSlide;
  currentSlide = (currentSlide - 1 + slides.length) % slides.length;
  slides[prevSlide].classList.remove('active');
  slides[currentSlide].classList.add('active');
  slides[currentSlide].style.animation = 'slideInLeft 1s forwards';
  slides[prevSlide].style.animation = 'slideOutRight 1s forwards';
}

let prevButton = document.querySelector('.prev');
let nextButton = document.querySelector('.next');

prevButton.addEventListener('click', prevSlide);
nextButton.addEventListener('click', nextSlide);

这个轮播图会在页面加载后每 3 秒自动切换一张图片，并且添加了向左和向右滑动的动画效果。您可以通过修改 CSS 样式或者 JavaScript 动画实现来调整轮播图的样式和效果。
