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, Default: "Alert")
  • buttonName: Button name (String) (Optional, Default: "OK")

Description

Most Cordova implementations use a native dialog box for this feature. However, some platforms simply use the browser's alert function, which is typically less customizable.

	    );

Windows Phone 7 and 8 Quirks

  • There is no built in browser alert, so if you want to just write alert('foo'); you can assign window.alert = navigator.notification.alert;
  • alert + confirm calls are non-blocking, and result is only available asynchronously.

Bada 2.x Quirks

  • alert uses javascript alert
