Shiny: 通过允许更多引导颜色使按钮更具可定制性

@dmpe ，鉴于 CSS 的工作方式，如果您分配两个不同的类，每个类指定不同的颜色，最后一个会胜出。 所以，在功能上，你已经可以在 Shiny 中做你想做的事了。 我意识到拥有两个颜色类可能看起来很笨重，但它是有效的 CSS。

这适用于所有闪亮按钮，如下所示：

library(shiny)
ui <- fluidPage(
  h3("Action Buttons"),
  actionButton("default", "Default"),
  actionButton("primary", "Primary", class = "btn-primary"),
  actionButton("secondary", "Secondary", class = "btn-secondary"),
  actionButton("success", "Success", class = "btn-success"),
  actionButton("info", "Info", class = "btn-info"),
  actionButton("warning", "Warning", class = "btn-warning"),
  actionButton("danger", "Danger", class = "btn-danger"),
  actionButton("link", "Link", class = "btn-link"),

  h3("Download Buttons"),
  downloadButton("default", "Default"),
  downloadButton("primary", "Primary", class = "btn-primary"),
  downloadButton("secondary", "Secondary", class = "btn-secondary"),
  downloadButton("success", "Success", class = "btn-success"),
  downloadButton("info", "Info", class = "btn-info"),
  downloadButton("warning", "Warning", class = "btn-warning"),
  downloadButton("danger", "Danger", class = "btn-danger"),
  downloadButton("link", "Link", class = "btn-link"),

  h3("Bookmark Buttons"),
  bookmarkButton("Default"),
  bookmarkButton("Primary", class = "btn-primary"),
  bookmarkButton("Secondary", class = "btn-secondary"),
  bookmarkButton("Success", class = "btn-success"),
  bookmarkButton("Info", class = "btn-info"),
  bookmarkButton("Warning", class = "btn-warning"),
  bookmarkButton("Danger", class = "btn-danger"),
  bookmarkButton("Link", class = "btn-link")
)
server <- function(input, output, session) {}
shinyApp(ui, server)

也许对于 bootstrap v4 :) 因为修复非常简单 - 只需添加一个新参数 :)

不，我们不太可能添加新的 a 参数，因为上面的代码已经足够清晰了。 添加复制现有功能的新参数是不好的做法。

由于提供了解决方法而关闭，但请不要犹豫进一步评论或创建新问题。
