r - 当闪亮的应用程序第一次启动时显示一个按钮，这将导致 tabItems 内容

问题描述

我有shiny下面的应用程序，其中包括 tabItems。我希望在第一次启动应用程序时显示actionbuttontabItems 内容之外的内容。然后当我按下它时，我将被移动到ConsenttabItem。该按钮从那里以后将不再有用，并且它应该消失，因为将显示 tabItems 的内容。

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
library(shinyjs)

mytitle <- paste0("")
dbHeader <- dashboardHeaderPlus(
  titleWidth = "0px",
  tags$li(a(
    div(style="display: inline;margin-top:-35px; padding: 0px 90px 0px 1250px ;font-size: 44px ;color:#001641;font-family:Chronicle Display Light; width: 500px;",HTML(mytitle)),
    
    
    div(style="display: inline;padding: 0px 0px 0px 0px;vertical-align:top; width: 150px;", actionButton("conse", "Consent", 
                                                                                                         style=" background-color: #faf0e6; border-color: #faf0e6")),
    
  ),
  class = "dropdown")
  
  
)

shinyApp(
  ui = dashboardPagePlus(
    header = dbHeader,
    sidebar = dashboardSidebar(width = "0px",
                               sidebarMenu(id = "sidebar", # id important for updateTabItems
                                           menuItem("Consent", tabName = "conse", icon = icon("line-chart"))
                               )           ),
    body = dashboardBody(
      tags$head(tags$style(HTML('
  
    '))),
      useShinyjs(),
      tags$script(HTML("$('body').addClass('fixed');")),
      
      tags$head(tags$style(".skin-blue .main-header .logo { padding: 0px;}")),
      
      actionButton("button", "Get started",style='padding:4px; font-size:140%'),
      tabItems(
        tabItem("conse",
textInput("pos", label = ("Position"), value = "")

                )
        

      )
      
    )
    
  ),
  server<-shinyServer(function(input, output,session) { 
    hide(selector = "body > div > header > nav > a")
    
    
    observeEvent(input$button, {
      
        updateTabItems(session, "sidebar",
                       selected = "conse")
      
      
    })
    
  }
  )
)
