我正在创建一个允许用户删除一些信息的应用程序。但是，我不想立即删除它，而是要确保被删除的文件是正确的文件。我遇到了shinyalerts允许显示“你确定吗？”的包。弹出。但是，我怎么知道用户选择了什么并将其传递给闪亮的？

library(shiny)
library(shinyalert)

shinyApp(
  ui = fluidPage(
    useShinyalert(),  # Set up shinyalert
    actionButton("btn", "Delete")
  ),
  server = function(input, output) {
    observeEvent(input$btn, {
      shinyalert(
        title = "Are you sure you want to delete this file?",
        text = "You will not be able to recover this imaginary file!",
        type = "warning",
        showCancelButton = TRUE,
        confirmButtonCol = '#DD6B55',
        confirmButtonText = 'Yes, delete it!'
      )

    })
  }
)
