Alert

Methods​

alert​

Launches an alert dialog with the specified title and message. Optionally, an array of buttons can be provided: on Android the maximum is 3, on iOS any number is okay.

On Android, the dialog can be dismissed by tapping outside of the alert box. This triggers the onDismiss callback available in the options. With the cancelable option, this behavior can be deactivated altogether.

alert Example​

open ReactNative

Alert.alert(
  ~title="Do you really want to quit?",
  ~message="We miss you already.",
  ~buttons=[
    Alert.button(
      ~text="OK",
      ~style=#destructive,
      ~onPress=() => Js.log("Bye!"),
      (),
    ),
    Alert.button(~text="Cancel", ~style=#cancel, ()),
  ],
  ~options=Alert.options(
    ~cancelable=true,
    ~onDismiss=_ => Js.log("Dismissed."),
    (),
  ),
