'Wheel' 触摸屏事件
'Wheel' events on touch screens
我有这个 fiddle https://jsfiddle.net/316n1xmL/1/，它可以完美地满足我在桌面上的需要。根据滚轮滚动方向向上或向下计数，并添加和删除 类。我 运行 关注的问题是如何在触摸屏上执行此操作。
我试过 hammer.js 但是他们的文档真的很糟糕而且不清楚。
遗憾的是，我正在构建的网站正在使用 bootstrap 4，这意味着我无法使用 juqery mobile，因为 BS4 使用 jquery 3，它不支持 jquery mobile。
感谢任何帮助

您需要通过检测触摸事件来重构您的插件。 Hammer 是一个很棒的库，可以涵盖所有手势类型。如果您需要更简单直接的东西，无论如何您都可以自己添加此功能 JavaScript:
添加功能检测和触摸处理程序：
if("ontouchstart" in window){
el.addEventListener('touchstart', touchStartHandler);
el.addEventListener('touchmove', touchMoveHandler);
el.addEventListener('touchend', touchEndHandler);
}
将实际位于您的 onwheel 处理程序中的代码放入它自己的函数中。
现在，您应该决定要在您的插件中实现什么行为：即滚动是在向下滑动期间发生，还是仅在松开手指后发生。在所需的触摸处理程序中使用该函数，在 touchmove 或 touchend 事件中。
因为你需要使用最新的 jQuery，我相信你不需要额外的向后跨浏览器兼容性，无论如何这里有一个例子：.
最后，您可以通过允许触摸操作稍微倾斜一点来为您的插件增加一些可用性，就像使用拇指一样。这是关于此主题的精彩讨论，包含您需要的所有源代码：A simple swipe detection on vanilla js
