notification.alert

Shows a custom alert or dialog box.

navigator.notification.alert(message, alertCallback, [title], [buttonName])

  • message: Dialog message. (String)

  • alertCallback: Callback to invoke when alert dialog is dismissed. (Function)

  • title: Dialog title. (String) (Optional, defaults to Alert)

  • buttonName: Button name. (String) (Optional, defaults to OK)

Windows Phone 7 and 8 Quirks

  • There is no built-in browser alert, but you can bind one as follows to call alert() in the global scope:

      window.alert = navigator.notification.alert;

  • Both alert and confirm are non-blocking calls, results of which are only available asynchronously.
