javascript - 如何在 JQuery 中禁用从一个列表框到另一个列表框的选定选项？

标签 javascript jquery html css

我有三个双列表框，我正在使用 jquery 和 bootstrap，我的问题是，只需要禁用一个列表框到另外两个列表框的选定选项。

例如

我有 3 个双列表框，如 box-1、box-2、box-3， 每个框有 3 个选项，如 opt1、opt2、opt3，如果我从 Box-1 选择一个选项 (opt1) 然后点击提交，提交后，然后那个选项 (opt1) 将禁用剩余的两个框(box-2 和 box-3)。

我尝试了很多方法来实现这一点，但我没有得到任何结果。

我希望我的问题是可以理解的
