如何在闪亮的应用程序中折叠sidebarPanel?

我有一个闪亮的应用程序,在navbarPage中的tabPanel内有一个mainPanel和一个sidebarPanel。我需要一个隐藏sidebarPanel的选项,类似于:Hide sidebar in default in shinydashboardhttps://github.com/daattali/shinyjs/issues/43

actionButton应该控制sidebarPanel是显示还是折叠。

这是代码:

library(shiny)
library(shinyjs)

ui <- fluidPage(
  navbarPage("",
             tabPanel("tab",
                      sidebarPanel(
                        useShinyjs()
                      ),

                      mainPanel(actionButton("showSidebar", "Show sidebar"),
                                actionButton("hideSidebar", "Hide sidebar")
                      )
             )
  )
)

server <-function(input, output, session) {
  observeEvent(input$showSidebar, {
    shinyjs::removeClass(selector = "body", class = "sidebarPanel-collapse")
  })
  observeEvent(input$hideSidebar, {
    shinyjs::addClass(selector = "body", class = "sidebarPanel-collapse")
  })
}

shinyApp(ui, server)

希望有人可以提供帮助:)

我修改了您的代码以隐藏并显示侧边栏。要为id创建sidebarPanel,我已将其包含在div中并为其指定id = Sidebar。要显示和隐藏侧边栏,我使用了shinyjs函数showhide,其ID为Sidebar

library(shiny)
library(shinyjs)

ui <- fluidPage(
  useShinyjs(),
  navbarPage("",
             tabPanel("tab",
                      div( id ="Sidebar",sidebarPanel(
                      )),


                      mainPanel(actionButton("showSidebar", "Show sidebar"),
                                actionButton("hideSidebar", "Hide sidebar")
                      )
             )
  )
)

server <-function(input, output, session) {
  observeEvent(input$showSidebar, {
    shinyjs::show(id = "Sidebar")
  })
  observeEvent(input$hideSidebar, {
    shinyjs::hide(id = "Sidebar")
  })
}

shinyApp(ui, server)

我用导航栏和多个选项卡上的切换按钮做了一个例子。

library(shiny)
library(shinyjs)

ui <- fluidPage(
  useShinyjs(),
  navbarPage(title = tagList("title",actionLink("sidebar_button","",icon = icon("bars"))),
             id = "navbarID",
             tabPanel("tab1",
                      div(class="sidebar"
                          ,sidebarPanel("sidebar1")
                      ),
                      mainPanel(
                        "MainPanel1"
                      )
             ),
             tabPanel("tab2",
                      div(class="sidebar"
                          ,sidebarPanel("sidebar2")
                      ),
                      mainPanel(
                        "MainPanel2"
                      )
             )
  )
)

server <-function(input, output, session) {
  
  observeEvent(input$sidebar_button,{
    shinyjs::toggle(selector = ".sidebar")
  })
  
}

shinyApp(ui, server)

========================================

我创建了一个不使用 sidepanel 类的更简单的示例,但我不确定它是否适用于所有环境。

library(shiny)
library(shinyjs)

ui <- fluidPage(
  useShinyjs(),
  navbarPage(title = tagList("title",actionLink("sidebar_button","",icon = icon("bars"))),
             tabPanel("tab1",
                      sidebarPanel("sidebar1"),
                      mainPanel("MainPanel1")
             ),
             tabPanel("tab2",
                      sidebarPanel("sidebar2"),
                      mainPanel("MainPanel2")
             )
  )
)

server <-function(input, output, session) {
  observeEvent(input$sidebar_button,{
    shinyjs::toggle(selector = ".tab-pane.active div:has(> [role='complementary'])")
  })
}

shinyApp(ui, server)

我终于完成了我的可折叠侧边栏面板,并且 Shinyjs runjs 允许您在侧栏面板折叠时扩展主面板的宽度。

library(shiny)
library(shinyjs)

ui <- fluidPage(
  useShinyjs(),
  navbarPage(title = tagList("title",actionLink("sidebar_button","",icon = icon("bars"))),
             tabPanel("tab1",
                      sidebarPanel("sidebar1",width=3),
                      mainPanel("MainPanel1",width=9,style="background-color:gray")
             ),
             tabPanel("tab2",
                        sidebarPanel("sidebar2",width=5)
                        ,mainPanel("MainPanel2",width=7,style="background-color:gray")
             )
  )
)

server <-function(input, output, session) {
  observeEvent(input$sidebar_button,{
    shinyjs::toggle(selector = ".tab-pane.active div:has(> [role='complementary'])")
    
    js_maintab <- paste0('$(".tab-pane.active div[role=',"'main'",']")')
    
    runjs(paste0('
          width_percent = parseFloat(',js_maintab,'.css("width")) / parseFloat(',js_maintab,'.parent().css("width"));
          if (width_percent == 1){
            ',js_maintab,'.css("width","");
          } else {
            ',js_maintab,'.css("width","100%");
          }
          '))
  })
}

以前评论中建议的切换选项示例。

library(shiny)
library(shinyjs)

ui <- fluidPage(
  useShinyjs(),
  navbarPage("",
             tabPanel("tab",
                      div( id ="Sidebar",sidebarPanel(
                      )),


                      mainPanel(actionButton("toggleSidebar", "Toggle sidebar")
                      )
             )
  )
)

server <-function(input, output, session) {
  observeEvent(input$toggleSidebar, {
    shinyjs::toggle(id = "Sidebar")
  })
}
