notification.alert

Shows a custom alert or dialog box.

navigator.notification.alert(message, alertCallback, [title], [buttonName])
  • message: Dialog message. (String)

  • 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
);

    //
    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 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.


notification.confirm

Displays a customizable confirmation dialog box.

navigator.notification.confirm(message, confirmCallback, [title], [buttonLabels])
  • message: Dialog message. (String)
  • confirmCallback: Callback to invoke with index of button pressed (1, 2, or 3) or when the dialog is dismissed without a button press (0). (Function)
  • title: Dialog title. (String) (Optional, defaults to Confirm)
  • buttonLabels: Comma-separated string specifying button labels. (String) (Optional, defaults to OK,Cancel)

Description

The notification.confirm method displays a native dialog box that is
more customizable than the browser’s confirm function.

confirmCallback

The confirmCallback executes when the user presses one of the
buttons in the confirmation dialog box.

The callback takes the argument buttonIndex (Number), which is the
index of the pressed button. Note that the index uses one-based
indexing, so the value is 1, 2, 3, etc.

Supported Platforms

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

Quick Example

// process the confirmation dialog result
function onConfirm(buttonIndex) {
    alert('You selected button ' + buttonIndex);
}
// Show a custom confirmation dialog
//
function showConfirm() {
    navigator.notification.confirm(
'You are the winner!', // message
 onConfirm,
// callback to invoke with index of button pressed
'Game Over',
   // title
'Restart,Exit'
 // buttonLabels
    );
}

<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">

    document.addEventListener("deviceready", onDeviceReady, false);
    // device APIs are available
    //
    function onDeviceReady() {
// Empty
    }
    // process the confirmation dialog result
    function onConfirm(buttonIndex) {
alert('You selected button ' + buttonIndex);
    }
    // Show a custom confirmation dialog
    //
    function showConfirm() {
navigator.notification.confirm(
'You are the winner!', // message
 onConfirm,
// callback to invoke with index of button pressed
'Game Over',
   // title
'Restart,Exit'
 // buttonLabels
);
    }
    </script>
  </head>
  <body>
    <p><a href="#" onclick="showConfirm(); return false;">Show Confirm</a></p>
  </body>
</html>

Windows Phone 7 and 8 Quirks

  • There is no built-in browser function for window.confirm, but you can bind it by assigning:

    window.confirm = navigator.notification.confirm;
    
  • Calls to alert and confirm are non-blocking, so the result is only available asynchronously.


notification.prompt

Shows a customizable prompt dialog box.

navigator.notification.prompt(message, promptCallback, [title], [buttonLabels], [defaultText])
  • message: Dialog message. (String)
  • promptCallback: Callback to invoke when a button is pressed. (Function)
  • title: Dialog title (String) (Optional, defaults to Prompt)
  • buttonLabels: Array of strings specifying button labels (Array) (Optional, defaults to ["OK","Cancel"])
  • defaultText: Default textbox input value (String) (Optional, Default: “Default text”)

Description

The notification.prompt method displays a native dialog box that is
more customizable than the browser’s prompt function.

promptCallback

The promptCallback executes when the user presses one of the buttons
in the prompt dialog box. The results object passed to the callback
contains the following properties:

  • buttonIndex: The index of the pressed button. (Number) Note that the index uses one-based indexing, so the value is 1, 2, 3, etc.
  • input1: The text entered in the prompt dialog box. (String)

Supported Platforms

  • Android
  • iOS

Quick Example

// process the promp dialog results
function onPrompt(results) {
    alert("You selected button number " + results.buttonIndex + " and entered " + results.input1);
}
// Show a custom prompt dialog
//
function showPrompt() {
    navigator.notification.prompt(
'Please enter your name',  // message
onPrompt,
      // callback to invoke
'Registration',
// title
['Ok','Exit'],
 // buttonLabels
'Jane Doe'
     // defaultText
    );
}
