The CurrencyFormatter class provides locale-sensitive formatting and parsing of currency values.

This class is a wrapper class around the flash.globalization.CurrencyFormatter. Therefore, the locale-specific formatting is provided by the flash.globalization.CurrencyFormatter. However, this CurrencyFormatter class can be used in MXML declarations, uses the locale style for the requested Locale ID name, and has methods and properties that are bindable.

The flash.globalization.CurrencyFormatter class uses the underlying operating system for the formatting functionality and to supply the locale specific data. On some operating systems, the flash.globalization classes are unsupported, on these systems this wrapper class provides fallback functionality.

CurrencyFormatter

()Construtor
public function CurrencyFormatter()

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 4.5
Versões de runtime: Flash Player 10.1, AIR 2.5

Constructs a new CurrencyFormatter object to format numbers representing currency amounts according to the conventions of a given locale.

The locale for this class is supplied by the locale style. The locale style can be set in several ways:

  • By using the class in an MXML declaration and inheriting the locale from the document that contains the declaration.
  • Example:
          <fx:Declarations> 
                 <s:CurrencyFormatter id="cf" /> 
          </fx:Declarations>
          
  • By using an MXML declaration and specifying the locale value in the list of assignments.
  • Example:
          <fx:Declarations> 
              <s:CurrencyFormatter id="cf_Japanese" locale="ja-JP" /> 
          </fx:Declarations>
          
  • Calling the setStyle() method, e.g. cf.setStyle("locale", "ja-JP")
  • Inheriting the style from a UIComponent by calling the UIComponent's addStyleClient() method.

If the locale style is not set by one of the above techniques, the instance of this class will be added as a StyleClient to the topLevelApplication and will therefore inherit the locale style from the topLevelApplication object when the locale dependent property getter or locale dependent method is called.

Most of the properties of this class are automatically set based on the locale style. If the locale style is changed, any properties that have not been explicitly set will also be updated based on the new locale. Note that the actual locale that is used is specified by the actualLocaleIDName property.

NOTE: When a fallback locale is used, the currency properties are set to default values, and therefore the currencySymbol or currencyISOCode properties might be given unexpected values. It is a good idea to examine the currencySymbol and currencyISOCode property values before formatting a currency amount.

Detalhes do método

format

()método
public function format(value:Object):String

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 4.5
Versões de runtime: Flash Player 10.1, AIR 2.5

Creates a string representing a currency amount formatted according to the current properties of this CurrencyFormatter object, including the locale, useCurrencySymbol, the currencySymbol, or the currencyISOCode properties.

The useCurrencySymbol property determines whether the format method uses the currencySymbol or the currencyISOCode in the formatted currency amount. The default value for useCurrencySymobl is false and thus by default currency amounts will be formatted with the currencyISOCode

Many countries and regions use the same currency symbols for different currencies. For example, the United States, Australia, New Zealand, Canada, and Mexico all use the same dollar sign symbol ($) for local currency values. When the formatting currency differs from the user's local currency it is best to use the ISO code as the currency string. You can use the formattingWithCurrencySymbolIsSafe() method to test whether or the ISO code of the currency to be formatted matches the default currency ISO code for the actual local used by the formatter.

This method can format numbers of very large and very small magnitudes. However, the number of significant digits is limited to the precision provided by the Number data type.

If there is an error when formatting, due to an illegal input value or other error, by default the format() method returns null. However if the errorText property is non-null, then the value of the errorText property is returned. The lastOperationStatus property is set to indicate the error that occurred.

Parâmetros

value:Object — An object that contains the numeric value to be formatted into a currency string. If the object is not a Number then it will be converted to a number using the Number() conversion function.

Retorna
String — A string containing the formatted currency value.

Exemplo  ( Como usar este exemplo )
In this example the locale style is set to fr-CA [French (Canada)]. The example assumes that this locale is supported in the user's operating system and therefore no fallback locale is used. For fr-CA, the default currency is Canadian dollars with an ISO code of CAD. Therefore when formatting a currency with the default values, CAD is used as the currency symbol. However when the useCurrencySymbol property is set to true, the currencySymbol property is used to format the currency amount.
      <fx:Declarations>
        <s:CurrencyFormatter id="cf_use_ISOCode" locale="fr-CA" />
        <s:CurrencyFormatter id="cf_use_Symbol" locale="fr-CA" 
                           useCurrencySymbol="true" />
      </fx:Declarations>
      
      <s:VGroup>
        <!-- label will use ISO code: 1,234,567.89 CAD -->
        <s:Label text="{cf_use_ISOCode.format(1234567.89)}" /> 
        <!-- label will use currency symbol: 1,234,567.89 $ -->
        <s:Label text="{cf_use_Symbol.format(1234567.89)}" /> 
      </s:VGroup>
     
      

The second example shows a method of formatting a currency amount in Canadian dollars using the default user's locale. The formattingWithCurrencySymbolIsSafe() method is used to set the value of useCurrencySymbol property. If the user's default locale is Canada (for example fr-CA or en-CA), then the default currency symbol for Canada is used. If there is some locale is the default, then the currencyISOCode of CAD will be used in the formatted currency amount.

      <fx:Declarations>
       <s:CurrencyFormatter id="cf_CAD" locale="{LocaleID.DEFAULT}"
        currencyISOCode="CAD"
        useCurrencySymbol="{cf_CAD.formattingWithCurrencySymbolIsSafe('CAD')}"
       />

formattingWithCurrencySymbolIsSafe

()método 
public function formattingWithCurrencySymbolIsSafe(requestedISOCode:String):Boolean

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 4.5
Versões de runtime: Flash Player 10.1, AIR 2.5

Determines whether the currently specified currency symbol can be used when formatting currency amounts.

Many regions and countries use the same currency symbols. This method can be used to safeguard against the use of an ambiguous currency symbol, or a currency symbol or ISO code that is different than expected due to the use of a fallback locale.

A common use case for this method is to determine whether to show a local currency symbol (if the amount is formatted in the user's default currency), or a more specific ISO code string (if the amount is formatted in a currency different from the user's default).

This method compares the requestedISOCode parameter against the actual locale's default currencyISOCode, returning true if the strings are equal and false if they are not. When the strings are equal, using the format() method with the useCurrencySymbol property set to true results in a formatted currency value string with a currency symbol that is used in the current locale. If this method returns false, then using the format() method with the useCurrencySymbol property set to true could result in the use of an ambiguous or incorrect currency symbol.

Parâmetros

requestedISOCode:String — A three letter ISO 4217 currency code (for example, USD for US dollars, EUR for Euros). Must contain three uppercase letters from A to Z.

Retorna
Booleantrue if the default currencyISOCode for the locale corresponding to the actualLocaleIDName matches the requestedISOCode parameter; otherwise false.

parse

()método 
public function parse(inputString:String):CurrencyParseResult

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 4.5
Versões de runtime: Flash Player 10.1, AIR 2.5

Parses a string into a currency amount and a currency symbol.

The parsing algorithm uses the value of the decimalSeparator property to determine the integral and fractional portion of the number. It uses the values of the negativeCurrencyFormat and positiveCurrencyFormat properties to determine the location of the currency symbol or string relative to the currency amount. For negative amounts the value of the negativeCurrencyFormat property determines the location of the negative symbol and whether parentheses are used.

If the order of the currency symbol, minus sign, and number in the input string does not match the pattern identified by the negativeCurrencyFormat and positiveCurrencyFormat properties, then:

  1. The value property of the returned CurrencyParseResult object is set to NaN.
  2. The currencyString property of the returned CurrencyParseResult object is set to null.
  3. The lastOperationStatus property is set to LastOperationStatus.PARSE_ERROR indicate that parsing failed.

The input string may include space characters, which are ignored during the parsing.

Parsing can succeed even if there is no currency symbol. No validation is done of the portion of the string corresponding to the currency symbol. If there is no currency symbol or string, the currencyString property in the returned CurrencyParseResult object is set to an empty string.

Parâmetros

inputString:String — The input string to parse.

Retorna
CurrencyParseResult — A CurrencyParseResult object containing the numeric value and the currency symbol or string.

Lança
TypeError — if the inputString parameter is null.
