# org.apache.cordova.globalization

This plugin obtains information and performs operations specific to the user's
locale, language, and timezone. Note the difference between locale and language:
locale controls how numbers, dates, and times are displayed for a region, while
language determines what language text appears as, independently of locale settings.
Often developers use locale to set both settings, but there is no reason a user
couldn't set her language to "English" but locale to "French", so that text is
displayed in English but dates, times, etc., are displayed as they are in France.
Unfortunately, most mobile platforms currently do not make a distinction between
these settings. 

## Installation

    cordova plugin add org.apache.cordova.globalization

## Objects

- GlobalizationError

## Methods

- navigator.globalization.getPreferredLanguage
- navigator.globalization.getLocaleName
- navigator.globalization.dateToString
- navigator.globalization.stringToDate
- navigator.globalization.getDatePattern
- navigator.globalization.getDateNames
- navigator.globalization.isDayLightSavingsTime
- navigator.globalization.getFirstDayOfWeek
- navigator.globalization.numberToString
- navigator.globalization.stringToNumber
- navigator.globalization.getNumberPattern
- navigator.globalization.getCurrencyPattern

## navigator.globalization.getPreferredLanguage

Get the BCP 47 language tag for the client's current language.

    navigator.globalization.getPreferredLanguage(successCallback, errorCallback);

### Description

Returns the BCP-47 compliant language identifier tag to the `successCallback` 
with a `properties` object as a parameter. That object should have a `value`
property with a `String` value.

If there is an error getting the language, then the `errorCallback`
executes with a `GlobalizationError` object as a parameter. The
error's expected code is `GlobalizationError.UNKNOWN_ERROR`.

### Supported Platforms

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

### Example

When the browser is set to the `en-US` language, this should display a
popup dialog with the text `language: en-US`:

    navigator.globalization.getPreferredLanguage(
        function (language) {alert('language: ' + language.value + '\n');},
        function () {alert('Error getting language\n');}
    );

### Android Quirks

- Returns the ISO 639-1 two-letter language code, upper case ISO 3166-1 
country code and variant separated by hyphens. Examples: "en", "en-US", "US"

### Windows Phone 8 Quirks

- Returns the ISO 639-1 two-letter language code and ISO 3166-1 country code
of the regional variant corresponding to the "Language" setting, separated by
a hyphen.
- Note that the regional variant is a property of the "Language" setting and
not determined by the unrelated "Country/Region" setting on Windows Phone.

## navigator.globalization.getLocaleName

Returns the BCP 47 compliant tag for the client's current locale setting.

    navigator.globalization.getLocaleName(successCallback, errorCallback);

### Description

Returns the BCP 47 compliant locale identifier string to the `successCallback`
with a `properties` object as a parameter. That object should have a `value`
property with a `String` value. The locale tag will consist of a two-letter lower
case language code, two-letter upper case country code, and (unspecified) variant
code, separated by a hyphen.

If there is an error getting the locale, then the `errorCallback`
executes with a `GlobalizationError` object as a parameter. The
error's expected code is `GlobalizationError.UNKNOWN_ERROR`.

### Supported Platforms

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

### Example

When the browser is set to the `en-US` locale, this displays a popup
dialog with the text `locale: en-US`.

    navigator.globalization.getLocaleName(
        function (locale) {alert('locale: ' + locale.value + '\n');},
        function () {alert('Error getting locale\n');}
    );

### Android Quirks

- Java does not distinguish between a set "langauge" and set "locale," so this
method is essentially the same as `navigator.globalizatin.getPreferredLanguage()`.

### Windows Phone 8 Quirks

- Returns the ISO 639-1 two-letter language code and ISO 3166-1 country code
of the regional variant corresponding to the "Regional Format" setting, separated
by a hyphen.


## navigator.globalization.dateToString

Returns a date formatted as a string according to the client's locale and timezone.

    navigator.globalization.dateToString(date, successCallback, errorCallback, options);

### Description

Returns the formatted date `String` via a `value` property accessible
from the object passed as a parameter to the `successCallback`.

The inbound `date` parameter should be of type `Date`.

If there is an error formatting the date, then the `errorCallback`
executes with a `GlobalizationError` object as a parameter. The
error's expected code is `GlobalizationError.FORMATTING_ERROR`.

The `options` parameter is optional, and its default values are:

    {formatLength:'short', selector:'date and time'}

The `options.formatLength` can be `short`, `medium`, `long`, or `full`.

The `options.selector` can be `date`, `time` or `date and time`.

### Supported Platforms

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

### Example

If the browser is set to the `en_US` locale, this displays a popup
dialog with text similar to `date: 9/25/2012 4:21PM` using the default
options:

    navigator.globalization.dateToString(
        new Date(),
        function (date) { alert('date: ' + date.value + '\n'); },
        function () { alert('Error getting dateString\n'); },
        { formatLength: 'short', selector: 'date and time' }
    );

### Windows Phone 8 Quirks

- The `formatLength` option supports only `short` and `full` values.

### Firefox OS Quirks

- `formatLength` is not distinguishing `long` and `full` 
- only one method of displaying date (no `long` or `full` version)

## navigator.globalization.getCurrencyPattern

Returns a pattern string to format and parse currency values according
to the client's user preferences and ISO 4217 currency code.

     navigator.globalization.getCurrencyPattern(currencyCode, successCallback, errorCallback);

### Description

Returns the pattern to the `successCallback` with a `properties` object
as a parameter. That object should contain the following properties:

- __grouping__: The grouping symbol to use for parsing and formatting. _(String)_

The inbound `currencyCode` parameter should be a `String` of one of
the ISO 4217 currency codes, for example 'USD'.

If there is an error obtaining the pattern, then the `errorCallback`
executes with a `GlobalizationError` object as a parameter. The
error's expected code is `GlobalizationError.FORMATTING_ERROR`.

### Supported Platforms

- Amazon Fire OS
- Android
- BlackBerry 10
- iOS

### Example

When the browser is set to the `en_US` locale and the selected
currency is United States Dollars, this example displays a popup
dialog with text similar to the results that follow:

    navigator.globalization.getCurrencyPattern(
        'USD',
        function (pattern) {
            alert('pattern: '  + pattern.pattern  + '\n' +
                  'code: '     + pattern.code     + '\n' +
                  'fraction: ' + pattern.fraction + '\n' +
                  'rounding: ' + pattern.rounding + '\n' +
