r - 使用操作按钮转到另一个选项卡

Question

我有以下 Shiny 的应用程序:

ui <- fluidPage(
  tabsetPanel(
    tabPanel("Tab 1",
      actionButton("switch_tab", "Go to the second tab")
    ),
    tabPanel("Tab 2", "there!"),
    tabPanel("Tab 3", "there!"))

)

server <- function(input, output, session) {

  observeEvent(input$switch_tab, {
    updateTabsetPanel(session, "inTabset",
                      selected = "Tab 3")
  })

}
shinyApp(ui = ui, server = server)

当我单击“转到第二个选项卡”按钮时，它基本上应该切换选项卡。然而，它不起作用。

关于我可能忽略的任何反馈？

您需要添加 id到tabsetpanel

library(shiny)
ui <- fluidPage(
        tabsetPanel(
                id="inTabset",
                tabPanel("Tab 1",actionButton("switch_tab", "Go to the third tab")
                ),
                tabPanel("Tab 2", "there!"),
                tabPanel("Tab 3", "there!"))

)

server <- function(input, output, session) {

        observeEvent(input$switch_tab, {
                updateTabsetPanel(session, "inTabset",selected = "Tab 3")
        })

}
shinyApp(ui = ui, server = server)
