jquery全屏轮播代码

jQuery 全屏轮播是一种常见的网页设计元素，用于展示一系列图片或内容，并且能够自动或手动切换显示内容。下面是一个简单的 jQuery 全屏轮播的实现示例：

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>jQuery Fullscreen Carousel</title>
<style>
  body, html { height: 100%; margin: 0; }
  .carousel {
    width: 100%;
    height: 100%;
    position: relative;
    overflow: hidden;
  }
  .carousel img {
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0;
    left: 0;
    opacity: 0;
    transition: opacity 1s ease-in-out;
  }
  .carousel img.active {
    opacity: 1;
  }
</style>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>

<div class="carousel">
  <img src="image1.jpg" alt="Image 1" class="active">
  <img src="image2.jpg" alt="Image 2">
  <img src="image3.jpg" alt="Image 3">
</div>

<script>
$(document).ready(function() {
  var images = $('.carousel img');
  var currentIndex = 0;

  function showImage(index) {
    images.removeClass('active').eq(index).addClass('active');
  }

  function nextImage() {
    currentIndex = (currentIndex + 1) % images.length;
    showImage(currentIndex);
  }

  setInterval(nextImage, 3000); // Change image every 3 seconds
});
</script>

</body>
</html>
