The CurrencyValidator class ensures that a String represents a valid currency amount according to the conventions of a locale. This class uses the locale style for specifying the Locale ID.

The validator can ensure that a currency string falls within a given range (specified by minValue and maxValue properties), is an integer (specified by domain property), is non-negative (specified by allowNegative property), correctly specifies negative and positive numbers, has the correct currency ISO code or currency symbol, and does not exceed the specified number of fractionalDigits. The validator sets default property values by making use of the flash.globalization.CurrencyFormatter class and therefore the locale specific values are supplied by the operating system.

The flash.globalization.CurrencyFormatter class uses the underlying operating system to supply the locale specific data. In case the operating system does not provide currency formatting, this class provides fallback functionality.

This property is used to validate the currency string or symbol present in the input currency amounts using the validate() method.

This property is initialized by the constructor based on the actual locale that is used. When a fallback locale is used this property reflects the preferred, default currency code for the fallback locale.

The default value is dependent on the actual locale and operating system.

A numeric value that indicates a validating pattern for negative currency amounts. This property defines the location of the currency symbol and the negative symbol or parentheses in relation to the numeric portion of the currency amount. This property is used to validate whether or not the input currency string follows this pattern for negative amounts.

The value of this property must be one of the constants defined in the table below.

The '¤' symbol represents the location of the currencyISOCode or the currencySymbol in the currency string.
The '-' character represents the location of the negativeNumberSymbol.
The 'n' character represents the currency amount.

Versión de producto:

Flex 4.5

Versiones de motor de ejecución:

Flash Player 10.1, AIR 2.5

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

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

Inheriting the style from a UIComponent by calling the UIComponent's addStyleClient method.
By using the class in an MXML declaration and inheriting the locale from the document that contains the declaration.

      <fx:Declarations>
             <s:CurrencyValidator id="cv" />
      </fx:Declarations>

By using an MXML declaration and specifying the locale value in the list of assignments.

      <fx:Declarations>
          <s:CurrencyValidator id="cv_turkish" locale="tr-TR" />
      </fx:Declarations>

Calling the setStyle method, For example: cv.setStyle("locale", "tr-TR")

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.

The properties related to the currency string format are set to default values based on the locale.

NOTE: When a fallback locale is used, the currency properties are set to default values of en_US locale, and therefore might not match the currency for which the validation is intended. It is a good idea to examine the currencySymbol and currencyISOCode property values before validating a currency amount.

Convenience method for calling a validator from within a custom validation function. Each of the standard Flex validators has a similar convenience method. Caller must check the ValidationResult objects in the returned array for validation status.

Parámetros

	`value:Object` — A currency number string to validate.The number string can use unicode minus symbols 0x2212, 0xFE63, 0xFF0D besides ascii minus.

	`baseField:String` — Text representation of the subfield specified in the `value` parameter. For example, if the `value` parameter specifies value.number, the `baseField` value is "number".

Valor devuelto

Array — An Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator.
