cordova-plugin-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.

This plugin defines global navigator.globalization object.

Although in the global scope, it is not available until after the deviceready event.

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

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
  • Windows
  • Browser

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.

Windows 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.

Browser Quirks

  • Falls back on getLocaleName

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
  • Windows
  • Browser

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.globalization.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.

Windows Quirks

  • Locale setting can be changed in Control Panel -> Clock, Language and Region -> Region -> Formats -> Format, and in Settings -> Region -> Regional Format on Windows Phone 8.1.

Browser Quirks

  • IE returns the locale of operating system. Chrome and Firefox return browser language tag.

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'}

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

Android Quirks

  • formatLength options are a subset of Unicode UTS #35. The default option short depends on a user selected date format within Settings -> System -> Date & time -> Choose date format, which provide a year pattern only with 4 digits, not 2 digits. This means that it is not completely aligned with ICU.

Windows Phone 8 Quirks

  • The formatLength option supports only short and full values.

  • The pattern for 'date and time' selector is always a full datetime format.

  • The returned value may be not completely aligned with ICU depending on a user locale.

Windows Quirks

  • The formatLength option supports only short and full values.

  • The pattern for 'date and time' selector is always a full datetime format.

  • The returned value may be not completely aligned with ICU depending on a user locale.

Browser Quirks

  • Only 79 locales are supported because moment.js is used in this method.

  • The returned value may be not completely aligned with ICU depending on a user locale.

  • time selector supports full and short formatLength only.

Firefox OS Quirks

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