如何在按钮的标签中包含动作链接？

Question

我的目标是在selectInput按钮的标签中包含一个操作链接（显示帮助文本）。

library(shiny)

ui <- fluidPage(
  br(),
  selectInput(
    inputId = "some_id", 
    label = "Please choose A or B (get help)",
    choices = c("choice A", "choice B"),
    selected = "choice A",
    selectize = F
  ),
  actionLink(inputId = "action_link", label = "get help")
) # fluidPage

server <- function(input, output) {}

shinyApp(ui, server)

我猜解决方案是使用label = HTML(...)，但我不知道如何用纯HTML重写操作链接。

Answer 1

  selectInput(
    inputId = "some_id", 
    label = HTML("Please choose A or B", 
                 as.character(actionLink(inputId = 'action_link', label = 'get help'))),
    choices = c("choice A", "choice B"),
    selected = "choice A",
    selectize = F
  )

Answer 2

您还可以使用tags，例如a和p

library(shiny)

ui <- fluidPage(
  br(),
  selectInput(
    inputId = "some_id", 
    label = p("Please choose A or B ",a("get help", href = "https://www.google.com/", target = "_blank")),
    choices = c("choice A", "choice B"),
    selected = "choice A",
    selectize = F
  )
) # fluidPage

server <- function(input, output) {}

shinyApp(ui, server)
