我出于日程安排的目的创建了这个 HTML + JavaScript 表格。它允许我选择表格中的多个单元格并将其输出到 JSON 文件中，并具有一些附加功能。
目前，当我尝试选择多个单元格时，它会正确创建“虚拟”矩形并选择所有需要的单元格。
我想要同样的取消选择，但出于某种原因我看不出问题是什么。
有人有什么想法吗？
这是代码片段。

</html>更新创建了 GIF，希望能更好地解释它: https://media.giphy.com/media/39yUQuAbdRSmfVfCll/giphy.gif-> 取消选择时，我必须逐个取消选择单元格，而不是取消选择多个单元格。
最佳答案
试试这个片段。我将总结我的更改(您可以将它们视为代码中的注释)
(1) determine if we're removing or adding based on the start cell
您需要根据起始单元格确定是删除集合还是添加集合。
(2) don't return here
您不想在删除单元格时返回，因为我们希望它运行删除范围的代码。
(3) remove or add each element here
这是最重要的变化。在 .each() 函数中，您需要实际删除或添加每个元素到集合中。为了提高可读性，我创建了名为 removeElement 和 addElement 的辅助函数。
我还建议您尝试重构您的代码，因为我看到很多重复的逻辑可以拆分成它们自己的函数。但是为了这个例子，我保持了大部分不变。
