Swiper持续自动滚动卡顿求助：需平滑滚动+鼠标悬停暂停

你的问题出在配置参数组合和CSS过渡设置上，以下是具体修正方案：

核心问题分析 #

1. autoplay.waitForTransition: true会让Swiper等待当前滚动过渡完成后再触发下一次滚动，导致出现停顿间隙
2. freeMode.momentum默认开启，会让滚动产生惯性，出现减速/加速的波动
3. CSS过渡函数没有正确作用在滚动容器上
4. autoplay.delay:1仍存在极小间隔，无法实现完全连续滚动

关键参数说明 #

• autoplay.delay: 0：取消滚动间隔，实现无缝连续滚动
• autoplay.waitForTransition: false：禁止等待过渡完成，避免停顿
• freeMode.momentum: false：关闭自由模式的惯性，保持匀速
• .swiper-wrapper { transition-timing-function: linear !important; }：强制滚动过渡为线性，确保速度恒定
