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 )
Bada 1.2 & 2.x
webOS

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
);

<!DOCTYPE html>
<html>
  <head>

    <script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>

	        'You are the winner!',  // message
	        alertDismissed,         // callback
	        'Game Over',            // title
	        'Done'                  // buttonName
	    );

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.

Bada 2.x Quirks

alert uses javascript alert
