javascript - 为什么滑块可以在桌面上工作，但不能在移动设备上工作？

问题描述

滑块功能似乎停止在平板电脑和移动设备上运行，但在桌面上运行良好。我不确定如何解决此功能。

我需要为移动设备添加“触摸”吗？如果是这样，添加它的最佳方法是什么？

我已经在所有浏览器上对其进行了测试，当在移动视图中查看时，该功能似乎被禁用。

解决方案

我通过以下网址查看了您的事件处理：https ://s3-us-west-2.amazonaws.com/guruscriptz/image-comparison.js

您似乎缺少移动事件。除了与鼠标相关的事件之外，您还需要 touchstart、touchend、touchmove 和 touchcancel 事件。这将允许非基于鼠标的点击移动滑块。

例如：

ragElement.parents().on("mousemove vmousemove"

应该

ragElement.parents().on("mousemove vmousemove touchmove"

等等
