r - 如果不使用 bsButton()，shinyBS Popover 将无法正常工作

Question

我正在与shinyBS-popovers 内的奇怪行为作斗争insertUI()。似乎只有在bsButton()某处包含 a 时才会添加弹出框。

您可以使用下面的示例。只要您取消注释 any bsButton(...)，弹出框就会起作用。

library(shinyBS)
library(shiny)
library(shinyWidgets)

# UI ---------------------------------------------------------------------------
ui <- basicPage(
    actionButton("show", "Create Input"),
    # uncomment me!
    # shinyBS::bsButton("id_button1", "A Button"),
    fluidRow(
        tags$div(id = 'placeholder',
                 style = "min-height: 400px;")
    )
)

# Server -----------------------------------------------------------------------
server <- function(input, output, session) {

    # insert checkbox when clicked
    observeEvent(input$show, {
        insertUI(selector = '#placeholder',
                 ui = tags$div(id = "id_div",
                               # uncomment me!
                               # shinyBS::bsButton("id_button2", "A Button"),
                               shinyWidgets::prettyCheckbox(
                                   inputId = "id_checkbox",
                                   label = "Click Me!"
                               )),
                 immediate = TRUE)

        addPopover(session, "id_div", "Hello", "Stranger")
    })
}

shinyApp(ui, server)
