根据选中的复选框启用和禁用两个不同的按钮 - JQuery

Question

我有一个表格，但我需要添加一些功能，以便如果您只选择一个选项，则单个操作菜单应处于活动状态，顶部操作菜单应显示为灰色。目前，如果选择一个选项，则会禁用表操作菜单并启用顶部操作菜单。有没有办法让它工作，这样如果只选择一条记录，顶部菜单就会被禁用。

目前工作原理：

全选 - 禁用表按钮并启用顶部按钮。如果取消选择全选，则该按钮将被禁用

如果从表中选择 2 个或更多，则禁用表按钮并启用顶部菜单。

如果有人能够给我一些建议，因为它让我难倒了。

Answer 1

所以我设法让它工作，经过很多挠头，我将计数更改为 1 这解决了这个问题。经过全面测试，它现在可以按预期执行。
