将ConditionalPanel与闪亮模块中选定的DT:datatable行一起使用

library(shiny)
library(shinydashboard)
library(DT)

ui <- dashboardPage(
  dashboardHeader(title = "ConditionalPanel with DT:datatable"),
  dashboardSidebar(
    sidebarMenu(
      menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard"))
    )
  ),
  dashboardBody(
    tabItems(
      tabItem(tabName = "dashboard",
              fluidRow(
                box(
                  title = "DT:datatable",
                  width = 6,
                  DT::dataTableOutput("table")
                ),
                box(
                  title = "ConditionalPanel",
                  width = 6,
                  conditionalPanel(
                    condition = "input.table_rows_selected.length > 0",
                    p("You have selected a row in the DT:datatable.")
                  )
                )
              )
      )
    )
  )
)

server <- function(input, output) {
  output$table <- DT::renderDataTable({
    datatable(iris, selection = "single")
  })
}

shinyApp(ui, server)
