Launch a confirmation dialog

Launch a popup to ask the user for confirmation.

confirmSweetAlert(
  session = getDefaultReactiveDomain(),
  inputId,
  title = NULL,
  text = NULL,
  type = "question",
  btn_labels = c("Cancel", "Confirm"),
  btn_colors = NULL,
  closeOnClickOutside = FALSE,
  showCloseButton = FALSE,
  allowEscapeKey = FALSE,
  cancelOnDismiss = TRUE,
  html = FALSE,
  ...
)

ask_confirmation(
  inputId,
  title = NULL,
  text = NULL,
  type = "question",
  btn_labels = c("Cancel", "Confirm"),
  btn_colors = NULL,
  closeOnClickOutside = FALSE,
  showCloseButton = FALSE,
  allowEscapeKey = FALSE,
  cancelOnDismiss = TRUE,
  html = FALSE,
  ...,
  session = shiny::getDefaultReactiveDomain()
)

Arguments

session: The session object passed to function given to shinyServer.
inputId: The input slot that will be used to access the value. If in a Shiny module, it use same logic than inputs : use namespace in UI, not in server.
title: Title of the alert.
text: Text of the alert, can contains HTML tags.
type: Type of the alert : info, success, warning or error.
btn_labels: Labels for buttons, cancel button (FALSE) first then confirm button (TRUE).
btn_colors: Colors for buttons.
closeOnClickOutside: Decide whether the user should be able to dismiss the modal by clicking outside of it, or not.
showCloseButton: Show close button in top right corner of the modal.
allowEscapeKey: If set to FALSE, the user can't dismiss the popup by pressing the Esc key.
cancelOnDismiss: If TRUE, when dialog is dismissed (click outside, close button or Esc key) it will be equivalent to canceling (input value will be FALSE), if FALSE nothing happen (input value remain NULL).
html: Does text contains HTML tags ?
...: Additional arguments (not used)
