Wijmo.Globalize

Globalize Class

Class that implements formatting and parsing of numbers and Dates.

By default, Globalize uses the American English culture. To switch cultures, include the appropriate wijmo.culture file after the wijmo files.

The example below shows how you can use the Globalize class to format dates, times, and numbers in different cultures:

Example

Heirarchy

  • Globalize

Methods

Static format

  • format(value: any, format: string, trim?: boolean, truncate?: boolean, defaultPrec?: number): string
  • Formats a number or a date.

    The format strings used with the format function are similar to the ones used by the .NET Globalization library. The tables below contains links that describe the formats available:

    Parameters

    • value: any

      Number or Date to format (all other types are converted to strings).

    • format: string

      Format string to use when formatting numbers or dates.

    • Optional trim: boolean

      Whether to remove trailing zeros from numeric results.

    • Optional truncate: boolean

      Whether to truncate the numeric values rather than round them.

    • Optional defaultPrec: number

      Precision to use if not specified in the format string.

    Returns string

    A string representation of the given value.

Static formatDate

  • formatDate(value: Date, format: string): string
  • Formats a date using the current culture.

    The format parameter contains a .NET-style Date format string with the following additions:

    • Q, q Calendar quarter.
    • U Fiscal quarter (government).
    • u Fiscal quarter (private sector).
    • EEEE, EEE, EE, E Fiscal year (government).
    • eeee, eee, ee, e Fiscal year (private sector).

    For example:

    import { Globalize } from '@mescius/wijmo';
    let dt = new Date(2015, 9, 1); // Oct 1, 2015
    console.log('result', Globalize.format(dt, '"FY"EEEE"Q"U') + ' (US culture)');
    **result** FY2016Q1 (US culture)

    Another addition is available for dealing with complex eras such as those defined in the Japanese culture:

    • ggg Era name (e.g. '平成', '昭和', '大正', or '明治').
    • gg Era initial (e.g. '平', '昭', '大', or '明').
    • g Era symbol (e.g. 'H', 'S', 'T', or 'M').

    Example

    Parameters

    • value: Date

      Number or Date to format.

    • format: string

      .NET-style Date format string.

    Returns string

    A string representation of the given date.

Static formatNumber

  • formatNumber(value: number, format: string, trim?: boolean, truncate?: boolean, defaultPrec?: number): string
  • Formats a number using the current culture.

    The formatNumber method accepts all .NET-style Standard Numeric Format Strings and provides support for scaling, prefixes, suffixes, and custom currency symbols.

    Numeric format strings take the form Axxsscc, where:

    • A is a single alphabetic character called the format specifier (described below).
    • xx is an optional integer called the precision specifier. The precision specifier affects the number of digits in the result.
    • ss is an optional string used to scale the number. If provided, it must consist of commas. The number is divided by 1000 for each comma specified.
    • cc is an optional string used to override the currency symbol when formatting currency values. This is useful when formatting currency values for cultures different than the current default (for example, when formatting Euro or Yen values in applications that use the English culture).

    The following table describes the standard numeric format specifiers and displays sample output produced by each format specifier for the default culture.

    c Currency: formatNumber(1234, 'c') => '$1,234.00'
    d Decimal (integers): formatNumber(-1234, 'd6') => '-001234'
    e Scientific Notation (lower-case 'e'): formatNumber(123.456, 'e6') => '1.234560e+2' E Scientific Notation (upper-case 'e'): formatNumber(123.456, 'E6') => '1.234560E+2' f Fixed-point: formatNumber(1234.5, 'f2') => '1234.50'
    F Fixed-point (with thousand separators): formatNumber(1234.5, 'F2') => '1,234.50'
    g General (no trailing zeros): formatNumber(1234.50, 'g2') => '1234.5'
    G General (no trailing zeros, thousand separators): formatNumber(1234.5, 'G2') => '1,234.5'
    n Number: formatNumber(1234.5, 'n2') => '1,234.50'
    p Percent: formatNumber(0.1234, 'p2') => '12.34%' P Percent (no thousand separators): formatNumber(12.34, 'P2') => '1234%' r Round-trip (same as g15): formatNumber(0.1234, 'r') => '0.1234' x Hexadecimal (integers): formatNumber(1234, 'x6') => '0004d2'

    The scaling specifier is especially useful when charting large values. For example, the markup below creates a chart that plots population versus GDP. The raw data expresses the population is units and the GDP in millions. The scaling specified in the axes formats causes the chart to show population in millions and GDP in trillions:

    import { FlexChart} from '@mescius/wijmo.chart';
    new FlexChart('#theChart', {
        itemsSource: countriesGDP,
        bindingX: 'pop',
        chartType: 'Scatter',
        series: [
            { name: 'GDP', binding: 'gdp' }
        ],
        axisX: {
            title: 'Population (millions)'
            format: 'n0,,'
        },
        axisY: {
            title: 'GDP (US$ trillions)'
            format: 'c0,,'
        }
    });

    The format string may also include constant prefix and suffix strings to be added to the output. If present, the prefix and suffix are specified as double-quoted strings at the start and end of the format string:

    import { Globalize } from '@mescius/wijmo';
    console.log(Globalize.formatNumber(value, '"thousands: "c3," k"'));
    console.log(Globalize.formatNumber(value, '"millions: "c1,," M"'));

    Parameters

    • value: number

      Number to format.

    • format: string

      .NET-style standard numeric format string (e.g. 'n2', 'c4', 'p0', 'g2', 'd2').

    • Optional trim: boolean

      Whether to remove trailing zeros from the result.

    • Optional truncate: boolean

      Whether to truncate the value rather than round it.

    • Optional defaultPrec: number

      Precision to use if not specified in the format string.

    Returns string

    A string representation of the given number.

Static getFirstDayOfWeek

  • getFirstDayOfWeek(): number
  • Gets the first day of the week according to the current culture.

    The value returned is between zero (Sunday) and six (Saturday).

    Returns number

Static getNumberDecimalSeparator

  • getNumberDecimalSeparator(): string
  • Gets the symbol used as a decimal separator in numbers.

    Returns string

Static parseDate

  • parseDate(value: string, format: string, refDate?: Date): Date
  • Parses a string into a Date.

    Two-digit years are converted to full years based on the value of the calendar's twoDigitYearMax property. By default, this is set to 2029, meaning two-digit values of 30 to 99 are parsed as 19xx, and values from zero to 29 are parsed as 20xx.

    You can change this threshold by assigning a new value to the calendar. For example:

    // get calendar
    var cal = wijmo.culture.Globalize.calendar;
    
    // default threshold is 2029, so "30" is parsed as 1930
    cal.twoDigitYearMax = 2029;
    var d1 = wijmo.Globalize.parseDate('30/12', 'yy/MM'); // dec 1930
    
    // changing threshold to 2100, so all values are parsed as 20**
    cal.twoDigitYearMax = 2100;
    var d2 = wijmo.Globalize.parseDate('30/12', 'yy/MM'); // dec 2030

    Parameters

    • value: string

      String to convert to a Date.

    • format: string

      Format string used to parse the date.

    • Optional refDate: Date

      Date to use as a reference in case date or time parts are not specified in the format string (e.g. format = 'MM/dd').

    Returns Date

    The Date object represented by the given string, or null if the string cannot be parsed into a Date.

Static parseFloat

  • parseFloat(value: string, format?: string): number
  • Parses a string into a floating point number.

    Parameters

    • value: string

      String to convert to a number.

    • Optional format: string

  • Parses a string into an integer.

    Parameters

    • value: string

      String to convert to an integer.

    • Optional format: string
