html实现文字轮转效果,原生JS实现旋转轮播图+文字内容切换效果【附源码】

好的，下面是实现文字轮转效果的 HTML 代码：

<div class="text-rotate">
  <span>第一段文字</span>
  <span>第二段文字</span>
  <span>第三段文字</span>
</div>

接下来是 CSS 代码：

.text-rotate {
  display: inline-block;
  animation: rotate 6s linear infinite;
}

@keyframes rotate {
  0% {
    transform: translateY(0);
  }
  25% {
    transform: translateY(-100%);
  }
  50% {
    transform: translateY(-200%);
  }
  75% {
    transform: translateY(-300%);
  }
  100% {
    transform: translateY(0);
  }
}

.text-rotate span {
  display: block;
}

这样就能实现文字轮转效果了。

接下来是实现旋转轮播图+文字内容切换效果的原生 JS 代码：

<div class="slider-container">
  <div class="slider">
    <div class="slide">
      <img src="image1.jpg" alt="">
      <div class="slide-caption">第一张图片</div>
    </div>
    <div class="slide">
      <img src="image2.jpg" alt="">
      <div class="slide-caption">第二张图片</div>
    </div>
    <div class="slide">
      <img src="image3.jpg" alt="">
      <div class="slide-caption">第三张图片</div>
    </div>
  </div>
  <div class="slider-controls">
    <button class="prev-slide">上一张</button>
    <button class="next-slide">下一张</button>
  </div>
</div>

接下来是 CSS 代码：

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

.slider {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

.slide {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  opacity: 0;
  transition: opacity 0.3s ease-in-out;
}

.slide.active {
  opacity: 1;
}

.slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}

.slide-caption {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  font-size: 2rem;
  color: #fff;
  text-shadow: 1px 1px 1px rgba(0, 0, 0, 0.5);
}

.slider-controls {
  position: absolute;
  bottom: 20px;
  left: 50%;
  transform: translateX(-50%);
}

.slider-controls button {
  padding: 10px;
  margin: 0 10px;
  font-size: 1.2rem;
  color: #fff;
  background-color: rgba(0, 0, 0, 0.5);
  border: none;
  border-radius: 4px;
  cursor: pointer;
  transition: background-color 0.3s ease-in-out;
}

.slider-controls button:hover {
  background-color: rgba(0, 0, 0, 0.8);
}

最后是 JavaScript 代码：

const slider = document.querySelector('.slider');
const slides = Array.from(slider.children);
const prevButton = document.querySelector('.prev-slide');
const nextButton = document.querySelector('.next-slide');
const slideWidth = slides[0].getBoundingClientRect().width;

// 设置幻灯片的位置
function setSlidePosition(slide, index) {
  slide.style.left = slideWidth * index + 'px';
}

// 设置幻灯片的顺序
slides.forEach(setSlidePosition);

// 移动幻灯片
function moveToSlide(slider, currentSlide, targetSlide) {
  slider.style.transform = 'translateX(-' + targetSlide.style.left + ')';
  currentSlide.classList.remove('active');
  targetSlide.classList.add('active');
}

// 点击按钮移动幻灯片
prevButton.addEventListener('click', function() {
  const currentSlide = slider.querySelector('.active');
  const prevSlide = currentSlide.previousElementSibling || slides[slides.length - 1];
  moveToSlide(slider, currentSlide, prevSlide);
});

nextButton.addEventListener('click', function() {
  const currentSlide = slider.querySelector('.active');
  const nextSlide = currentSlide.nextElementSibling || slides[0];
  moveToSlide(slider, currentSlide, nextSlide);
});

// 自动播放幻灯片
let sliderInterval = setInterval(function() {
  const currentSlide = slider.querySelector('.active');
  const nextSlide = currentSlide.nextElementSibling || slides[0];
  moveToSlide(slider, currentSlide, nextSlide);
}, 5000);

// 鼠标悬停停止自动播放
slider.addEventListener('mouseover', function() {
  clearInterval(sliderInterval);
});

// 鼠标离开开始自动播放
slider.addEventListener('mouseout', function() {
  sliderInterval = setInterval(function() {
    const currentSlide = slider.querySelector('.active');
    const nextSlide = currentSlide.nextElementSibling || slides[0];
    moveToSlide(slider, currentSlide, nextSlide);
  }, 5000);
});

这样就能实现旋转轮播图+文字内容切换效果了。
