# cordova-plugin-dialogs

This plugin provides access to some native dialog UI elements
via a global `navigator.notification` object.

Although the object is attached to the global scoped `navigator`, it is not available until after the `deviceready` event.

    document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() {
        console.log(navigator.notification);
    }

## Installation

    cordova plugin add cordova-plugin-dialogs

## Methods

- `navigator.notification.alert`
- `navigator.notification.confirm`
- `navigator.notification.prompt`
- `navigator.notification.beep`

## navigator.notification.alert

Shows a custom alert or dialog box.  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.

    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`)


### Example

    function alertDismissed() {
        // do something
    }

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

### Supported Platforms

- Amazon Fire OS
- Android
- BlackBerry 10
- Firefox OS
- iOS
- Tizen
- Windows Phone 7 and 8
- Windows 8
- Windows

### 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.

### Firefox OS Quirks:

Both native-blocking `window.alert()` and non-blocking `navigator.notification.alert()` are available.

### BlackBerry 10 Quirks
`navigator.notification.alert('text', callback, 'title', 'text')` callback parameter is passed the number 1.

## navigator.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__: Array of strings specifying button labels. _(Array)_  (Optional, defaults to [`OK,Cancel`])


### 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.

### Example

    function onConfirm(buttonIndex) {
        alert('You selected button ' + buttonIndex);
    }

    navigator.notification.confirm(
        'You are the winner!', // message
         onConfirm,            // callback to invoke with index of button pressed
        'Game Over',           // title
        ['Restart','Exit']     // buttonLabels
    );

### Supported Platforms

- Amazon Fire OS
- Android
- BlackBerry 10
- Firefox OS
- iOS
- Tizen
- Windows Phone 7 and 8
- Windows 8
- Windows

### 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.

### Windows Quirks

- On Windows8/8.1 it is not possible to add more than three buttons to MessageDialog instance.

- On Windows Phone 8.1 it's not possible to show dialog with more than two buttons.

### Firefox OS Quirks:

Both native-blocking `window.confirm()` and non-blocking `navigator.notification.confirm()` are available.

## navigator.notification.prompt

Displays a native dialog box that is more customizable than the browser's `prompt` function.

    navigator.notification.prompt(message, promptCallback, [title], [buttonLabels], [defaultText])

- __message__: Dialog message. _(String)_

- __promptCallback__: 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 `Prompt`)

- __buttonLabels__: Array of strings specifying button labels _(Array)_ (Optional, defaults to `["OK","Cancel"]`)

- __defaultText__: Default textbox input value (`String`) (Optional, Default: empty string)

### 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)_

### Example

    function onPrompt(results) {
        alert("You selected button number " + results.buttonIndex + " and entered " + results.input1);
    }

    navigator.notification.prompt(
        'Please enter your name',  // message
        onPrompt,                  // callback to invoke
        'Registration',            // title
        ['Ok','Exit'],             // buttonLabels
        'Jane Doe'                 // defaultText
    );

### Supported Platforms

- Amazon Fire OS
- Android
- Firefox OS
- iOS
- Windows Phone 7 and 8
- Windows 8
- Windows

### Android Quirks

- Android supports a maximum of three buttons, and ignores any more than that.

- On Android 3.0 and later, buttons are displayed in reverse order for devices that use the Holo theme.

### Windows Quirks

- On Windows prompt dialog is html-based due to lack of such native api.

### Firefox OS Quirks:

Both native-blocking `window.prompt()` and non-blocking `navigator.notification.prompt()` are available.

## navigator.notification.beep

The device plays a beep sound.

    navigator.notification.beep(times);

- __times__: The number of times to repeat the beep. _(Number)_

### Example

    // Beep twice!
    navigator.notification.beep(2);

### Supported Platforms

- Amazon Fire OS
- Android
- BlackBerry 10
- iOS
- Tizen
- Windows Phone 7 and 8
- Windows 8

### Amazon Fire OS Quirks

- Amazon Fire OS plays the default __Notification Sound__ specified under the __Settings/Display & Sound__ panel.

### Android Quirks

- Android plays the default __Notification ringtone__ specified under the __Settings/Sound & Display__ panel.

### Windows Phone 7 and 8 Quirks

- Relies on a generic beep file from the Cordova distribution.

### Tizen Quirks

- Tizen implements beeps by playing an audio file via the media API.

- The beep file must be short, must be located in a `sounds` subdirectory of the application's root directory, and must be named `beep.wav`.
