Internationalization

13 Jun 202424 minutes to read

The Internationalization library provides support for formatting and parsing date and number objects using the official Unicode CLDR JSON data. The en-US locale is set as default culture and USD is set as default _currencyCode_ for all Syncfusion JavaScript UI controls.

Loading culture data

Syncfusion CLDR data package contains only JSON data files generated using the official Unicode CLDR JSON data. This helps users avoid utilizing the existing cldr-data package, which has third-party library vulnerabilities. The loadCldr function is required to load the following CLDR data for cultures other than en-US.

NOTE

Syncfusion CLDR data package is published based on the releases of the Unicode CLDR JSON data. The package will be published within a week after the official Unicode CLDR JSON data is released.

Individual file path reference

Syncfusion CLDR data can be loaded by referring to individual paths from the package below, such as:

File Name	Path
ca-gregorian	@syncfusion/ej2-cldr-data/main/en/ca-gregorian.json
timeZoneNames	@syncfusion/ej2-cldr-data/main/en/timeZoneNames.json
numbers	@syncfusion/ej2-cldr-data/main/en/numbers.json
currencies	@syncfusion/ej2-cldr-data/main/en/currencies.json
numberingSystems	@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json

Single file path reference

Syncfusion CLDR data can also be loaded by referring to a single path from the package below, such as:

File Name	Path
ca-gregorian, timeZoneNames, numbers, currencies	@syncfusion/ej2-cldr-data/main/en/all.json
numberingSystems	@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json

Note: For en, dependency files are already loaded in the library.

Installing CLDR data

Syncfusion CLDR data is available as npm package. So, we can install it through below command to our package.

npm install @syncfusion/ej2-cldr-data

Binding to i18n library

The i18n library to use the CLDR data to format, parse number and date/time values in a way that is appropriate for the en culture. The loadCldr function takes two arguments, enNumberData and enTimeZoneData, which are the CLDR data for numbers and time zones, respectively, for the en culture.

import { loadCldr } from '@syncfusion/ej2-base';
import enNumberData from "@syncfusion/ej2-cldr-data/main/en/numbers.json";
import entimeZoneData from "@syncfusion/ej2-cldr-data/main/en/timeZoneNames.json";
loadcldr(enNumberData, entimeZoneData);

Changing global culture and currency code

To set the default culture and the currency code for all Syncfusion JavaScript UI controls, you can use the methods setCulture for setting the default locale and setCurrencyCode for setting the currency code.

import {setCulture, setCurrencyCode} from '@syncfusion/ej2-base';
setCulture('ar');
setCurrencyCode('QAR');

Note: If global culture is not set, then en-US is set as the default locale, and USD is set as the default currency code.

Manipulating numbers

Supported format string

Based on the NumberFormatOptions number formatting and parsing operations are processed. You need to specify some or all of the following properties mentioned below table.

No	Properties	Description
1	`format`	Denotes the format to be set .Possible values are 1. N - denotes numeric type. 2. C - denotes currency type. 3. P - denotes percentage type. E.g: `formatNumber`( 1234344 ,{format:'N4'}). Note: If no format is specified it takes numeric as default format type.
2	`minimumFractionDigits`	Indicates the minimum number of fraction digits. Possible values are 0 to 20.
3	`maximumFractionDigits`	Indicates the maximum number of fraction digits. Possible values are 0 to 20.
4	`minimumSignificantDigits`	Indicates the minimum number of significant digits. Possible values are 1 to 21. Note: If `minimumSignificantDigits` is given it is mandatory to give `maximumSignificantDigits`
5	`maximumSignificantDigits`	Indicates the maximum number of significant digits. . Possible values are 1 to 21. Note: If `maximumSignificantDigits` is given it is mandatory to give `minimumSignificantDigits`
6	`useGrouping`	Indicates whether to enable the group separator or not . By default grouping value will be true.
7	`minimumIntegerDigits`	Indicates the minimum number of the integer digits to be placed in the value. Possible values are 1 to 21.
8	`currency`	Indicates the currency code which needs to considered for the currency formatting.

Note: The minimumIntegerDigits, minimumFractionDigits and maximumFractionDigits are categorized
as group one,
minimumSignificantDigits and maximumSignificantDigits are categorized as group two.
If group two properties are defined, then the group one properties will be ignored.

Custom number formatting and parsing

Custom number formatting and parsing can also be achieved by directly specifying the pattern in the format property of NumberFormatOptions. One or more of the custom format specifiers listed in the table below can be used to create custom number format.

Specifier	Description	Input	Format Output
0	Replaces the zero with the corresponding digit if one is present. Otherwise, zero appears in the result string.	`instance.formatNumber`(123,{format: ‘0000’ })	‘0123’
#	Replaces the “#” symbol with the corresponding digit if one is present; otherwise, no digit appears in the result string.	`instance.formatNumber`(1234,{format: ‘####’ })	‘1234’
.	Denotes the number of digits allowed after the decimal points if it’s not specified then no need to specify decimal point values.	`instance.formatNumber`(546321,{format: ‘###0.##0#’ })	‘546321.000’
%	Percent specifier denotes the percentage type format.	`instance.formatNumber`(1,{format: ‘0000 %’ })	‘0100 %’
$	Denotes the currency type format based on the global currency code specified.	`instance.formatNumber`(13,{format: ‘$ ###.00’ });	‘$ 13.00’
;	Denotes separate formats for positive, negative and zero values.	`instance.formatNumber`(-120,{format: ‘###.##;(###.00);-0’});	‘(120.00)’
‘String’ (single Quotes)	Denotes the characters enclosed within single Quote(‘) to be replaced in the resultant string.	`instance.formatNumber`(-123.44,{format: “####.## ‘@’”})	‘123.44 @’

Note: If a custom format pattern is specified, other NumberFormatOptions properties will not be considered.

Custom formats

To use the custom date and time formats we need to specify the date/time pattern directly in the format property.
Custom format string must contain one or more of the following standard date/time symbols

Symbols	Description
G	Denotes the era in the date
y	Denotes the year.
M / L	Denotes month.
E / c	Denotes the day of week.
d	Denotes the day of month.
h / H	Denotes the hour. h for 12 hour and H for 24 hours format.
m	Denotes minutes.
s	Denotes seconds.
a	Denotes the am/pm designator it will only be displayed if hour is specified in the h format.
z	Denotes the time zone.
’ (single quotes)	To display words in the formatted date you can specify the words with in the single quotes

Custom format example

import { Internationalization } from '@syncfusion/ej2-base';

let intl: Internationalization = new Internationalization();
let formattedString: string =  intl.formatDate(new Date('1/12/2014 10:20:33'), { format: '\'year:\'y' \'month:\' MM' });
//Output: "year:2014 month:01"

Note: If the format property is given as an option, other properties are not considered.

Date Parsing

`getDateParser`

The getDateParser method will return a function that parses a given string based on the DateFormatOptions specified.

index.js
index.html
var intl = new ej.base.Internationalization();
var dParser = intl.getDateParser({skeleton: 'full', type: 'dateTime'});
var val = dParser('Friday, November 4, 2016 at 1:03:04 PM GMT+05:30');
document.querySelector('.result').innerHTML = val.toString();
