我有一个 jsfiddle 代码来记录单击图像的时间和位置。它适用于任何桌面平台，但滚动和突出显示文本 block 在 iPad 上的 chrome 或 safari 上不起作用。因此，作为一种解决方法，我希望能够复制 javascript 生成的点击和时间列表，但不确定如何。任何想法将不胜感激。

最佳答案
我能够使用 CSS user-select 让它工作，我添加了值 all为了演示选择，如果您在 Chrome Mac 上进行测试，请双击并按住 2 秒钟，它将选择文本并出现右键菜单(Mac 如何在 Mac OS 上模拟触摸选择)。
更新 :我在我的机器 iPad/iPhone 模拟器 safari 浏览器上对此进行了测试，并为我工作!无论如何，也许有什么问题:
