Description

Simple shiny alert that uses 'JavaScript' promises

Usage

shiny_alert2(
  title = "Alert",
  text = "",
  icon = c("info", "warning", "success", "error"),
  danger_mode = FALSE,
  auto_close = TRUE,
  buttons = NULL,
  on_close = NULL,
  session = shiny::getDefaultReactiveDomain()
)

close_alert2(session = shiny::getDefaultReactiveDomain())

Arguments

title	title of the alert
text	alert body text (pure text)
icon	which icon to display, choices are 'info', 'success' 'warning', and 'error'
danger_mode	true or false; if true, then the confirm button turns red and the default focus is set on the cancel button instead. To enable danger mode, buttons must be TRUE as well
auto_close	whether to close automatically when clicking outside of the alert
buttons	logical value or a named list, or characters. If logical, it indicates whether buttons should be displayed or not; for named list, the names will be the button text, see example; for characters, the characters will be the button text and value
on_close	NULL or a function that takes in one argument. If function is passed in, then it will be executed when users close the alert
session	shiny session, see domains

Value

a temporary input ID, currently not useful

Examples

library(shiny)
library(dipsaus)
ui <- fluidPage(
  use_shiny_dipsaus(),
  actionButtonStyled('btn', 'btn')

server <- function(input, output, session) {
  observeEvent(input$btn, {
    shiny_alert2(
      on_close = function(value) {
        cat("Modal closed!\n")
        print(value)
