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)

Description

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

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Tizen
  • Windows Phone 7 and 8
  • Windows 8

Quick Example

// Android / BlackBerry WebWorks (OS 5.0 and higher) / iOS / Tizen
//
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-x.x.x.js"></script>
    <script type="text/javascript" charset="utf-8">

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

    // device APIs are available

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

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

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.
