pauseOnFocusLoss

Boolean, whether to pause the toast on focus loss

draggable

Boolean, ability to drag the toast to remove it

draggableDirection

"x" or "y"

draggablePercent

the percentage of the width of the toast needed to remove it by dragging

pauseOnHover

Boolean, whether to pause the toast on hover

className

name of a CSS class applied to the container

toastClassName

name of a CSS class applied on the toast wrapper

bodyClassName

name of a CSS class applied on the toast body

progressClassName

name of a CSS class applied on the progress bar

style

inline style applied to the container, e.g. list(boxShadow = "rgba(0, 0, 0, 0.56) 0px 22px 30px 4px")

Rcallback

a R function without arguments to be executed whenever the toast is closed; alternatively, use the id argument (see details)

JScallback

some JavaScript code given as a string to be executed whenever the toast is closed, e.g. 'alert("The toast is closed")'

Value

No return value, called for side effect.

Details

Usage of the id argument. If you provide a string to the id argument, say "mytoast", the application will send the event input[["mytoast_closed"]] to the server whenever the toast closes; therefore you can listen to this event with an observer to perform an action whenever the toast closes.

Examples

# NOT RUN {
library(shiny)
library(shinyToastify)

ui <- fluidPage(
  useShinyToastify(),
  br(),
  actionButton("btn", "Show toast", class = "btn-primary btn-lg")
)

server <- function(input, output, session){

  toastTransitions <- c(
    "Zoom", "Bounce", "Flip", "Slide"
  )

  observeEvent(input[["btn"]], {

    toastTransition <- toastTransitions[1L + (input[["btn"]] %% 4L)]

    html <- HTML(
      '<span style="font-size: 30px; font-family: cursive;">',
      paste0(toastTransition, " transition"),
      '</span>',
    )

    showToast(
      session,
      input,
      text = html,
      type = "success",
      transition = tolower(toastTransition),
      autoClose = 3000,
      style = list(
