如何在点击操作按钮后显示隐藏的标签? [英] How to show hidden tabs after clicking an actionButton?
本文介绍了如何在点击操作按钮后显示隐藏的标签?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
actionButton
后显示它们。我发现这个post,但建议的解决方案使用navbarPage
。我尝试使用sidebarPanel
更改示例:
library(shiny)
library(shinyjs)
ui <- fluidPage(useShinyjs(),
tags$head(tags$style(HTML("#hello li a[data-value = 'tab2_val'], #hello li a[data-value = 'tab3_val']
{ display: none;}"))),
# Application title
titlePanel("My app"),
sidebarLayout(
sidebarPanel(
tabsetPanel("hello", id="hello",
tabPanel("home", br(), h3("Click the button"),actionButton("enter", "enter")),
tabPanel("tab2", value = "tab2_val", br(), h4("this is tab2")),
tabPanel("tab3 with a lot of stuff in it", value = "tab3_val", br(), h4("this is tab3"))),
mainPanel(
)
)
)
)
server <- function(input, output, session) {
observeEvent(input$enter, {
show(selector = '#hello li a[data-value="tab3_val"]')
show(selector = '#hello li a[data-value="tab2_val"]')
})}
shinyApp(ui, server)
但我收到以下错误:
错误:导航容器需要我尝试在此post中运行建议的解决方案,但仍收到相同的错误。我想这是因为我拥有的闪亮版本(1.7.1)。bslib::nav()
/shiny::tabPanel()
和/或bslib::nav_menu()
/shiny::navbarMenu()
。请考虑使用header
或footer
如果希望将内容放在每个面板的上方(或下方) 内容。
有人能帮我吗?
我附上一个可重复使用的例子。我们的想法是隐藏Tab2和Tab3,当您单击actionButton
提交&q;时,它们会出现。
library(shiny)
library(dplyr)
library(ggplot2)
ui <- fluidPage(
titlePanel("My app"),
sidebarLayout(
sidebarPanel(
tabsetPanel(
tabPanel("Tab1",
checkboxInput("log2", "Log2 transformation", value = FALSE),
actionButton("submit", "Submit")
),
tabPanel("Tab2",
radioButtons(inputId = "plot_type", label = "I want to see the plot of:",
c("All the samples" = "all_samples",
"Groups" = "samples_group")),
conditionalPanel(
condition = "input.plot_type == 'samples_group'",
style = "margin-left: 20px;",
checkboxGroupInput("group", "Choose the group:",
choices = c("Group1", "Group2", "Group3"))),
actionButton("show_plot", "See the plot")
),
tabPanel("Tab3",
numericInput("alpha", "Opacity of the plot", value=0.2),
checkboxInput(inputId = "Kruskalpval", label = "Show the Kruskal Wallis p-value", value = FALSE),
conditionalPanel(
condition = "input.Kruskalpval == '1'",
style = "margin-left: 20px;",
checkboxInput(inputId = "changeKW", "I want to change the place of the value", value=FALSE),
conditionalPanel(
condition = "input.changeKW == '1'",
numericInput(inputId = "X_axis", "X_axis:", value=2),
numericInput(inputId = "Y_axis", "Y_axis:", value=70)
)
),
actionButton("show_plot_2", "See the plot")
)
)
),
mainPanel(
plotOutput("boxplots")
)
)
)

以下是隐藏/显示第二个选项卡的代码。其他选项卡的代码类似。
library(shiny)
js <- "$(document).ready(function(){
var $tab2 = $('#hello li > a[data-value=tab2_val]').parent();
$tab2.removeClass('active').addClass('hide');
$('#enter').on('click', function(){
$tab2.removeClass('hide');
});
});
"
ui <- fluidPage(
tags$head(
tags$script(HTML(js))
),
# Application title
titlePanel("My app"),
sidebarLayout(
sidebarPanel(
tabsetPanel(
tabPanel(
"home", br(), h3("Click the button"), actionButton("enter", "enter")
),
tabPanel(
"tab2", value = "tab2_val", br(), h4("this is tab2")
),
tabPanel(
"tab3 with a lot of stuff in it", value = "tab3_val", br(),
h4("this is tab3")
),
id = "hello"
)
),
mainPanel()
)
)
server <- function(input, output, session) {
}
shinyApp(ui, server)
