Jquery版轮播图超详细

以下是一个使用jQuery实现的轮播图的示例代码，包含了基本的功能和样式：

HTML部分：




<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>jQuery 轮播图</title>
<style>
  .carousel {
    position: relative;
    width: 300px;
    height: 200px;
    margin: auto;
  }
  .carousel-inner {
    position: absolute;
    width: 100%;
    height: 100%;
    overflow: hidden;
  }
  .carousel-inner img {
    width: 100%;
    height: 100%;
  }
  .carousel-dots {
    position: absolute;
    bottom: 10px;
    left: 50%;
    transform: translateX(-50%);
  }
  .carousel-dot {
    display: inline-block;
    width: 10px;
    height: 10px;
    border-radius: 50%;
    background-color: #ccc;
    margin: 0 5px;
    cursor: pointer;
  }
  .carousel-dot.active {
    background-color: #333;
  }
</style>
</head>
<body>
 
<div class="carousel">
  <div class="carousel-inner">
    <img src="image1.jpg" alt="Image 1">
    <img src="image2.jpg" alt="Image 2">
    <img src="image3.jpg" alt="Image 3">
  </div>
  <div class="carousel-dots">
    <span class="carousel-dot active"></span>
    <span class="carousel-dot"></span>
    <span class="carousel-dot"></span>
  </div>
</div>
 
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
  $(document).ready(function() {
    let $carousel = $('.carousel');
    let $carouselInner = $carousel.find('.carousel-inner');
    let $carouselDots = $carousel.find('.carousel-dots');
    let $carouselDot = $carouselDots.find('.carousel-dot');
    let currentIndex = 0;
 
    function goToSlide(index) {
      currentIndex = index;
      $carouselInner.animate({ left: `-${100 * index}%` }, 500);
      $carouselDot.eq(index).addClass('active').siblings().removeClass('active');
    }
 
    $carouselDot.on('click', function() {
      let dotIndex = $(this).index();
      goToSlide(dotIndex);
    });
 
    setInterval(function() {
      let nextIndex = (currentIndex + 1) % $carouselDot.length;
      goToSlide(nextIndex);
    }, 3000);
  });
</script>
 
</body>
</html>

这段代码实现了一个简单的自动轮播图，包括图片切换和点点导航。轮播图可以自动播放，并且可以通过点击对应的点点来手动切换图片。这个例子提供了一个基本的轮播图实现参考，可以根据实际需求进行功能扩展和样式调整。
