Question

我在我构建的应用程序中广泛使用库shinythemes。我试图利用bsModal软件包中的shinyBS注意到＆＃39;淡入＆＃39; div永远不会离开我，因为没有任何可点击的网页应用程序。

来自shinyBS::bsModal的例子都很好（它们是无声的主题）。如何在使用模态的同时继续使用主题？

示例应用程序：

library(shiny)
library(shinyBS)
library(shinythemes)

app = shinyApp(
  ui =
    navbarPage(title=NULL,
      id="navbar",
      theme = shinytheme("journal"),
      tabPanel("test",
        column(1),
        column(3,
          sliderInput("bins",
            "Number of bins:",
            min = 1,
            max = 50,
            value = 30),
          actionButton("tabBut", "View Table")
        ),
        column(7,
          plotOutput("distPlot"),
          bsModal("modalExample", "Data Table", "tabBut", size = "large",
            dataTableOutput("distTable"))
        )
      )
    ),
  server =
    function(input, output, session) {

      output$distPlot <- renderPlot({

        x    <- faithful[, 2]
        bins <- seq(min(x), max(x), length.out = input$bins + 1)

        # draw the histogram with the specified number of bins
        hist(x, breaks = bins, col = 'darkgray', border = 'white')

      })

      output$distTable <- renderDataTable({

        x    <- faithful[, 2]
        bins <- seq(min(x), max(x), length.out = input$bins + 1)

        # draw the histogram with the specified number of bins
        tab <- hist(x, breaks = bins, plot = FALSE)
        tab$breaks <- sapply(seq(length(tab$breaks) - 1), function(i) {
          paste0(signif(tab$breaks[i], 3), "-", signif(tab$breaks[i+1], 3))
        })
        tab <- as.data.frame(do.call(cbind, tab))
        colnames(tab) <- c("Bins", "Counts", "Density")
        return(tab[, 1:3])

      }, options = list(pageLength=10))

    }
)

runApp(app)

我不知道导致冲突的原因，但解决方法是直接指定主题的链接。将theme = shinytheme("journal")替换为theme = "http://bootswatch.com/journal/bootstrap.css"，调整您正在使用的主题的名称。

Shiny - bsModal全都变得灰暗闪亮
