今天给大家封装一个简单的轮播图,可以点击下一张上一张以及自动轮播
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>走马灯示例</title> <style> body { font-family: Arial, sans-serif; background-color: #f9f9f9; display: flex; justify-content: center; align-items: center; height: 100vh; margin: 0; } .carousel-container { position: relative; width: 80%; max-width: 600px; overflow: hidden; border-radius: 10px; box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1); } .carousel { display: flex; transition: transform 0.5s ease; } .carousel-item { min-width: 100%; box-sizing: border-box; padding: 20px; background-color: #fff; border: 1px solid #ddd; border-radius: 10px; text-align: center; } .carousel-button { position: absolute; top: 50%; transform: translateY(-50%); background-color: rgba(0, 0, 0, 0.5); border: none; color: #fff; padding: 10px; cursor: pointer; border-radius: 50%; font-size: 18px; } .carousel-button.prev { left: 10px; } .carousel-button.next { right: 10px; } .carousel-button:hover { background-color: rgba(0, 0, 0, 0.7); } </style> </head> <body> <div class="carousel-container"> <div class="carousel"> <div class="carousel-item">项目 1</div> <div class="carousel-item">项目 2</div> <div class="carousel-item">项目 3</div> <div class="carousel-item">项目 4</div> <div class="carousel-item">项目 5</div> </div> <button class="carousel-button prev" onclick="prevSlide()">❮</button> <button class="carousel-button next" onclick="nextSlide()">❯</button> </div> <script> var currentIndex = 0; function showSlide(index) { var carousel = document.querySelector('.carousel'); var items = document.querySelectorAll('.carousel-item'); var totalItems = items.length; if (index >= totalItems) { currentIndex = 0; } else if (index < 0) { currentIndex = totalItems - 1; } else { currentIndex = index; } var offset = -currentIndex * 100; carousel.style.transform = 'translateX(' + offset + '%)'; } function nextSlide() { showSlide(currentIndex + 1); } function prevSlide() { showSlide(currentIndex - 1); } // 自动播放功能 setInterval(function() { nextSlide(); }, 3000); // 每3秒切换一次 </script> </body> </html>
如上图所示的效果,需要修改下样式更好看
