如何在Rstudio中添加多个bsPopovers而不会覆盖？

Question

最后一个弹出窗口会覆盖所有其他

我想在Shinydashboard内的几个ValueBox上添加多个弹出框。我正在为每个框使用具有唯一ID的bsPopover（）。但是，我将所有弹出窗口都写在一个辅助文件中，并在ui.r中调用该文件的源代码。 问题是，最后一个弹出窗口会覆盖所有内容，在userInterface上，我只能看到我添加的最后一个弹出窗口。

helper.r

bsPopover(
  id = "one", title = "ONE",
  content = "blah blah blah 1",
  trigger = "hover",
  placement = "right",
  options = list(container="body"))


bsPopover(
  id = "two", title = "TWO",
  content = "blah blah blah 2",
  trigger = "hover",
  placement = "right",
  options = list(container="body"))


bsPopover(
  id = "three", title = "THREE",
  content = "blah blah blah 3",
  trigger = "hover",
  placement = "bottom",
  options = list(container="body"))

ui.r

source("helper.r"),

您必须将它们包装在list()中才能起作用：

library(shiny)
library(shinydashboard)
library(shinyBS)

writeLines(text = 'myPopovers = list(
  bsPopover(
  id = "one", title = "ONE",
  content = "blah blah blah 1",
  trigger = "hover",
  placement = "right",
  options = list(container="body")),
  bsPopover(
    id = "two", title = "TWO",
    content = "blah blah blah 2",
    trigger = "hover",
    placement = "right",
    options = list(container="body")),
  bsPopover(
    id = "three", title = "THREE",
    content = "blah blah blah 3",
    trigger = "hover",
    placement = "bottom",
    options = list(container="body"))
  )', con = "helper.R")

source("helper.R")

ui <- dashboardPage(
  dashboardHeader(title = "Value boxes"),
  dashboardSidebar(),
  dashboardBody(
    fluidRow(
      valueBoxOutput("one"),
      valueBoxOutput("two"),
      valueBoxOutput("three"),
      myPopovers
    )
  )
)

server <- function(input, output) {
  output$one <- renderValueBox({
    valueBox(
      "25%", "Progress", icon = icon("list"),
      color = "purple"
    )
  })

  output$two <- renderValueBox({
    valueBox(
      "80%", "Approval", icon = icon("thumbs-up", lib = "glyphicon"),
      color = "yellow"
    )
  })

  output$three <- renderValueBox({
    valueBox(
      "90%", "Approval", icon = icon("thumbs-up", lib = "glyphicon"),
      color = "green"
    )
  })
}

shinyApp(ui, server)

结果：
