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.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iPhone
  • Windows Phone 7 ( Mango )

Quick Example

// Android / BlackBerry WebWorks (OS 5.0 and higher) / iPhone
//
function alertDismissed() {
    // do something
}

navigator.notification.alert(
    'You are the winner!',  // message
    alertDismissed,         // callback
    'Game Over',            // title
    'Done'                  // buttonName
);

Full Example

<!DOCTYPE html>
<html>
  <head>
    <title>Notification Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova-1.6.1.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Wait for Cordova to load
    //
    document.addEventListener("deviceready", onDeviceReady, false);

    // Cordova is ready
    //
    function onDeviceReady() {
        // Empty
    }

    // alert dialog dismissed
    function alertDismissed() {
        // do something
    }

    // Show a custom alert
    //
    function showAlert() {
	    navigator.notification.alert(
	        'You are the winner!',  // message
	        alertDismissed,         // callback
	        'Game Over',            // title
	        'Done'                  // buttonName
	    );
    }

    </script>
  </head>
  <body>
    <p><a href="#" onclick="showAlert(); return false;">Show Alert</a></p>
  </body>
</html>

Windows Phone 7 Quirks

  • Ignores button names, always uses 'OK'
  • 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.
