单击示例中的标记之一后,我尝试在新选项卡中折叠边栏。侧栏应保留在“主仪表板”选项卡中
带有数据的小示例应用
library(shiny)
library(leaflet)
library(shinydashboard)
library(purrr)
library(shinyjs)
pts <- data.frame(
id= letters[seq( from = 1, to = 10 )],
x = rnorm(10, mean = -93.625),
y = rnorm(10, mean = 42.0285))
ui部分,其中应隐藏的边栏元素为id="Sidebar"
,useShinyjs()
ui <- dashboardPage(
dashboardHeader(title = "Test"),
dashboardSidebar(
sidebarMenu(id="Sidebar",
actionLink("remove", "Remove detail tabs"))),
dashboardBody(
useShinyjs(), # not really sure where this has to go?
tabsetPanel(
id = "tabs",
tabPanel(
title = "Main Dashboard",
value = "page1",
fluidRow(tabsetPanel(id='my_tabsetPanel',
tabPanel('Map1',
leafletOutput('map1')
)))))))
我在Eventobserver()
内添加appendTab
的服务器部分,该部分应识别出已打开新标签并隐藏侧边栏
###server
server <- function(input, output, session) {
tab_list <- NULL
output$map1 <- renderLeaflet({
leaflet() %>%
addTiles() %>%
setView(-93.65, 42.0285, zoom = 6)
})
observe({
input$my_tabsetPanel
tab1 <- leafletProxy('map1', data = pts) %>%
clearMarkers() %>%
addCircleMarkers(lng = ~x, lat = ~y, radius = 4, layerId = ~id)})
observeEvent(input$map1_marker_click, {
clickedMarker <- input$map1_marker_click[1]
tab_title <- paste(clickedMarker)
appendTab(inputId = "my_tabsetPanel",
tabPanel(
tab_title,
fluidRow(
box('test')
)))
tab_list <<- c(tab_list, tab_title)
observeEvent(input$tabs == "my_tabsetPanel", { #also not sure if this is at the right place?
shinyjs::hide(id = "Sidebar")
})
updateTabsetPanel(session, "my_tabsetPanel", selected = tab_title)
})
observeEvent(input$remove,{
tab_list %>%
walk(~removeTab("my_tabsetPanel", .x))
tab_list <<- NULL
})}
shinyApp(ui = ui, server = server)
