我目前正试图找到一种方法来隐藏/显示R Shiny中的整个box()元素(以及里面的所有内容) . 我想创建一个可能是一个按钮,允许用户扩展一个特定的框,然后用相同(甚至不同)的按钮隐藏它 . 我不想使用conditionalPanel,因为我的应用程序非常大并且会产生一些问题 .
示例代码可以在下面找到:
library(shiny)
library(shinydashboard)
library(collapsibleTree)
require(colorspace)
# Dataset is from https://community.tableau.com/docs/DOC-1236
load(system.file("extdata/Superstore_Sales.rda", package = "collapsibleTree"))
# For the sake of speed, let's only plot sales in Ontario
Superstore_Sales <- Superstore_Sales[Superstore_Sales$Region=="Ontario",]
# Define UI for application that draws a collapsible tree
ui <- fluidPage(
# Application title
titlePanel("Collapsible Tree Example 3: Gradient Mapping"),
# Sidebar with a select input for the root node
sidebarLayout(
sidebarPanel(
tags$a(href = "https://community.tableau.com/docs/DOC-1236", "Sample dataset from Tableau")
),
# Show a tree diagram with the selected root node
mainPanel(
box(title="Tree Output",width='800px',
collapsibleTreeOutput("plot", height = "500px")
),
box(title="Input",
selectInput(
"hierarchy", "Tree hierarchy",
choices = c(
"Customer Segment", "Product Category", "Product Sub-Category",
"Order Priority", "Product Container"
),
selected = c("Customer Segment","Product Category", "Product Sub-Category"),
multiple = TRUE
),
selectInput(
"fill", "Node color",
choices = c("Order Quantity", "Sales", "Unit Price"),
selected = "Sales"
)
)
)
)
)
# Define server logic required to draw a collapsible tree diagram
server <- function(input, output) {
output$plot <- renderCollapsibleTree({
collapsibleTreeSummary(
Superstore_Sales,
hierarchy = input$hierarchy,
root = input$fill,
attribute = input$fill
)
})
}
# Run the application
shinyApp(ui = ui, server = server)
主要思想是有一个按钮(或按钮)属于每个框,并隐藏/显示该特定框 . 也许有可能使用shinyjs,但我似乎无法理解它应该如何与我目前的结构一起工作 .

这是一个可以扩展到实际应用程序的最小示例 .
它使用
shinyjs
来显示/隐藏框 . 关键是给框id
,然后在show
/hide
函数中使用id
值而不是检查它是否可以被2整除为什么不在
shinyjs
中使用toggle
功能
