【问题描述】：
我的闪亮仪表板中有五个选项卡。这五个选项卡中的四个有自己的表格。这些表格中的每一个都彼此不同，并且具有不同的日期范围。我希望有一个选项，即当用户在其中一个选项卡中输入日期输入时，它不会影响其他表及其输入范围。但是，对于我下面的代码，情况并非如此。如果我在第一个选项卡中选择日期范围，这将影响其他选项卡中显示的日期。下面是我的代码
#ui.R

我一直在网上寻找答案，并将继续在网上寻找答案，但我没有看到与此问题完全相关的任何内容。有没有办法在 dateInputeRange 上放置一个 ID，以便服务器端的 reactive({}) 函数知道 dateinpute 范围来自选项卡 1 、 2 等。
【问题讨论】：
-
您的 dateRangeInput 将 inputId 作为参数。您可以分配不同的 ID，例如date_user、date_finance 等，而不仅仅是“日期”。然后在该选项卡中过滤时引用每个特定的 date_id。或者，您可以构建一个多次调用的模块。
-
这确实解决了问题。如果您想将此作为答案，我将选择它作为问题的解决方案。
