点击切换Bootstrap轮播图分类后，罗盘分类轮播无法滑动

问题原因 #

Bootstrap的Carousel组件初始化时，只会绑定页面中第一个.carousel-inner容器的轮播事件逻辑。你当前用了两个独立的.carousel-inner容器，切换到罗盘分类后，轮播控件的点击事件仍然绑定在第一个（锤子分类的）容器上，自然无法控制第二个容器的轮播滑动。

解决方法 #

把所有分类的轮播项合并到同一个.carousel-inner容器中，给不同分类的轮播项添加专属类名，切换分类时通过类名控制显隐，同时重置当前分类的激活项，最后调用轮播实例方法更新状态。

修改后的JS代码 #

// 提前初始化轮播实例
const carousel = new bootstrap.Carousel(document.getElementById('carouselex'));

function compassFunc() {
    // 隐藏锤子分类项，移除激活状态
    document.querySelectorAll('.hammer-item').forEach(item => {
        item.classList.add('d-none');
        item.classList.remove('active');
    });
    // 显示罗盘分类项
    document.querySelectorAll('.compass-item').forEach(item => {
        item.classList.remove('d-none');
    });
    // 激活罗盘分类第一个项
    document.querySelector('.compass-item').classList.add('active');
    // 重置轮播到当前分类第一张，恢复轮播逻辑
    carousel.to(0);
    carousel.cycle();
}

function hammerFunc() {
    // 隐藏罗盘分类项，移除激活状态
    document.querySelectorAll('.compass-item').forEach(item => {
        item.classList.add('d-none');
        item.classList.remove('active');
    });
    // 显示锤子分类项
    document.querySelectorAll('.hammer-item').forEach(item => {
        item.classList.remove('d-none');
    });
    // 激活锤子分类第一个项
    document.querySelector('.hammer-item').classList.add('active');
    // 重置轮播到当前分类第一张，恢复轮播逻辑
    carousel.to(0);
    carousel.cycle();
}

补充说明 #

• 合并轮播容器后，Bootstrap Carousel能识别所有轮播项，控件事件可以正常绑定
• 切换时重置激活项，确保轮播从当前分类的第一张开始展示
• 调用to(0)和cycle()方法，强制更新轮播状态，恢复滑动和自动播放逻辑
