在Swiper.js中控制分页滚动速度非常简单,通过配置speed参数即可实现。这个参数定义了幻灯片切换时的动画持续时间,单位是毫秒(ms)。
以下是一个具体示例,展示如何设置和调整分页滚动的速度:

// 创建新实例,配置分页滚动和速度

// 应用速度按钮
document.getElementById('applySpeed').addEventListener('click', () => {

speed:控制分页滚动的动画速度,单位是毫秒(ms)speed: 500 表示滚动动画持续500毫秒(默认值)通过调整speed参数,你可以精确控制Swiper分页滚动的动画节奏,使其更符合你的网站交互需求和用户体验目标。
