shiny - 在 Shiny 中显示/隐藏 bsCollapse 面板

Question

我正在使用 ShinyBS 和 Shinyjs 包构建一个闪亮的应用程序，我想根据另一个 bscollapse 面板中单选按钮上的输入来隐藏/显示 bscollapse 面板。

在 Parent1 中选择“AAA”或“BBB”选项时，我只想在 Parent2 中显示“AAAA”和“BBBB”折叠面板。

在 Parent1 中选择“CCC”或“DDD”选项时，我只想在 Parent2 中显示“CCCC”和“DDDD”折叠面板。

我正在使用 shinyjs 包中的 show() 和 hide() 命令，但我无法使其工作。When "AAA" or "BBB" is selected, nothing is appearing in Parent2, which is not what I want.

下面是重现问题的代码：

library(shiny)
library(shinyBS)
library(shinyjs)

server = function(input, output, session) {

observeEvent(input$TypeRadio,{
if (input$TypeRadio == "AAA" || input$TypeRadio == "BBB")
  shinyjs::show("collapse1")
  shinyjs::hide("collapse2")
})

observeEvent(input$TypeRadio,{
if (input$TypeRadio == "CCC" || input$TypeRadio == "DDD")
  shinyjs::show("collapse2")
  shinyjs::hide("collapse1")})
}


ui = fluidPage(
shinyjs::useShinyjs(),

bsCollapse(id = "collapseExample", multiple = FALSE,
bsCollapsePanel("Parent1","",

              radioButtons("TypeRadio", "",
                           choices = list("AAA" = "AAA",
                                          "BBB" = "BBB",
                                          "CCC" = "CCC",
                                          "DDD" = "DDD"),
                           inline = FALSE)),


bsCollapsePanel("Parent2","",

              bsCollapse(id = "collapse1",   
                         bsCollapsePanel("AAAA", ""),
                         bsCollapsePanel("BBBB", "")),

              bsCollapse(id = "collapse2",   
                         bsCollapsePanel("CCCC", ""),
                         bsCollapsePanel("DDDD", ""))

                         )
 )                 
 )
shinyApp(ui = ui, server = server)

    server = function(input, output, session){

      observeEvent(input$TypeRadio,{

    }
