Introduction

jSignage adds support for locale-dependent display of date, time, numbers, and currencies using a subset of the Unicode Common Locale Data Repository data base.

A locale is identified by its Unicode tag, which is a string composed of two or three parts: a language subtag and a region subtag, plus an optional script subtag - for example, en_US for US English (default locale), zh_Hans_CN for mainland China, and es_MX for the Mexican locale. For more details, see the list of supported locale tags.

The default locale can be obtained by a call to $.getLocale(), and changed by a call to $.setLocale( tag ).

The Localization API is based on two class-functions:

  • $.DateTimeFormat for the formatting of date and time
  • $.NumberFormat for the formatting of numbers and currencies

.DateTimeFormat()

$.DateTimeFormat( format, locale);

Returns: Function

Description

Class for the formatting of date and time. To use it, create an object by calling the class constructor with a format selector and an optional locale tag (the default locale is used if not provided).

Parameters

  • format
    Type: Number or String. (required)
    The format selector for date and time is either one of the predefined numeral formats (such as $.DateTimeFormat.Format.FULL_DATETIME) or a pattern string (such as "EEEE, MMMM d, y" which is expanded to "Wednesday, July 10, 1996" for en_US) - for more details see Date and time formats.
  • locale
    Type: String.
    Optional locale code tag.

.NumberFormat()

$.NumberFormat( format, locale);

Returns: Function

Description

Class for the formatting of numbers and currencies. To use it, create an object by calling the class constructor with a format selector and an optional locale tag (the default locale is used if not provided).

Parameters

  • format
    Type: Number or String. (required)
    The format selector for numbers and currencies is either one of the predefined formats (such as $.NumberFormat.Format.DECIMAL) or a pattern string (such as "#.#####"" which specifies that the number can have up to 5 decimals) - for more details see Number formats.
  • locale
    Type: String.
    Optional locale code tag.

.getLocale()

$.getLocale();

Returns: String

This function gets the default locale. It doesn't have any parameters.

.setLocale()

$.setLocale( locale );

Returns: String

This function sets the default locale; it also returns the previous default locale. It takes one parameter:

  • locale
    Type: String.
    Locale code tag.

Examples

  // formatting date, time and numbers 

  $.setLocale( 'es_ES' ); // sets the default locale

  f = new $.DateTimeFormat( $.DateTimeFormat.Format.LONG_DATE );
  str = f.format( new Date() );   // -> "24 de abril de 2013"

  f = new $.DateTimeFormat( "dd/MM/yyyy" );
  str = f.format( new Date() );   // -> "24/04/2013"

  f = new $.DateTimeFormat( $.DateTimeFormat.Format.LONG_DATE, 'zh_Hans_CN'  );
  str = f.format( new Date() );   // -> "2013年4月24日"

  f = new $.NumberFormat( $.NumberFormat.Format.DECIMAL );
  str = f.format( Math.PI );    // -> "3.142"

  f = new $.NumberFormat( "#.#####" );
  str = f.format( Math.PI );    // -> "3.14159"
