Bootstrap响应式轮播缩略图移动端布局异常问题求助

嘿，我来帮你解决这个轮播的适配问题！你想要的效果是：桌面端一次展示4张缩略图组，整组切换；移动端改成一次只显示1张，逐张滑动。咱们直接上修改后的代码，再给你拆解关键调整点：

        if ($(window).width() >= 1200) {
            const currentIndex = $(this).find('.item.active').index();

});
</script>

关键调整点说明 #

1. 重构轮播项结构：把原来每个轮播项里的4张卡片，拆成每张卡片单独作为一个轮播项，这样移动端默认就能逐张切换。同时给卡片容器加了col-xs-12 col-lg-3，保证移动端占满整行，桌面端每行刚好4张。
2. 响应式CSS控制：
   • 桌面端用flex布局让4个轮播项并排显示，设置每个项宽度为25%；
   • 移动端把每个轮播项宽度设为100%，一次只显示一张。
3. JS优化切换逻辑：监听轮播的切换事件，在桌面端时强制一次切换4个轮播项，保持整组切换的体验；移动端则保持默认的逐张切换。
4. 指示器更新：因为轮播项数量变成了12个，所以同步更新了指示器的数量，确保每个卡片都有对应的指示器。

这样调整后，就能完美实现你想要的效果啦！
