JavaScript部分：

// 获取轮播元素
var carousel = document.querySelector('.carousel');
var carouselList = carousel.querySelector('.carousel-list');
var carouselItems = carouselList.querySelectorAll('.carousel-item');
var carouselIndicators = carousel.querySelector('.carousel-indicators').querySelectorAll('li');
var currentIndex = 0;
var timer;

// 显示指定的轮播项
function showCarouselItem(index) {
  // 更新当前轮播项索引
  currentIndex = index;
  
  // 更新轮播项的显示状态
  carouselItems.forEach(function(item, i) {
    if (i === currentIndex) {
      item.classList.add('active');
    } else {
      item.classList.remove('active');
    }
  });
  
  // 更新指示器的显示状态
  carouselIndicators.forEach(function(indicator, i) {
    if (i === currentIndex) {
      indicator.classList.add('active');
    } else {
      indicator.classList.remove('active');
    }
  });
}

// 开始轮播
function startCarousel() {
  timer = setInterval(function() {
    var nextIndex = currentIndex + 1;
    if (nextIndex >= carouselItems.length) {
      nextIndex = 0;
    }
    showCarouselItem(nextIndex);
  }, 3000);
}

// 停止轮播
function stopCarousel() {
  clearInterval(timer);
}

// 绑定事件
carousel.addEventListener('mouseover', function() {
  stopCarousel();
});

carousel.addEventListener('mouseout', function() {
  startCarousel();
});

carouselIndicators.forEach(function(indicator, i) {
  indicator.addEventListener('click', function() {
    showCarouselItem(i);
  });
});

// 显示第一项轮播项
showCarouselItem(0);

// 开始轮播
startCarousel();
