Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 3
Versões de runtime: Flash Player 9, AIR 1.1


Ao iniciar com Flex 4.5, a Adobe recomenda que você use a classe de spark.validators.NumberValidator como uma alternativa a esta classe.

The NumberValidator class ensures that a String represents a valid number. It can ensure that the input falls within a given range (specified by minValue and maxValue), is an integer (specified by domain), is non-negative (specified by allowNegative), and does not exceed the specified precision. The validator correctly validates formatted numbers (e.g., "12,345.67") and you can customize the thousandsSeparator and decimalSeparator properties for internationalization.

Sintaxe MXMLexpandedOcultar sintaxe MXML

The <mx:NumberValidator> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

  <mx:NumberValidator 
    allowNegative="true|false" 
    decimalPointCountError="The decimal separator can only occur once." 
    decimalSeparator="." 
    domain="real|int" 
    exceedsMaxError="The number entered is too large." 
    integerError="The number must be an integer." 
    invalidCharError="The input contains invalid characters." 
    invalidFormatCharsError="One of the formatting parameters is invalid." 
    lowerThanMinError="The amount entered is too small." 
    maxValue="NaN" 
    minValue="NaN" 
    negativeError="The amount may not be negative." 
    precision="-1" 
    precisionError="The amount entered has too many digits beyond the decimal point." 
    separationError="The thousands separator must be followed by three digits." 
    thousandsSeparator="," 
  />

Detalhes do construtor

NumberValidator

()Construtor
public function NumberValidator()

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 3
Versões de runtime: Flash Player 9, AIR 1.1

Constructor.

Detalhes do método

doValidation

()método
override protected function doValidation(value:Object):Array

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 3
Versões de runtime: Flash Player 9, AIR 1.1

Override of the base class doValidation() method to validate a number.

You do not call this method directly; Flex calls it as part of performing a validation. If you create a custom Validator class, you must implement this method.

Parâmetros

value:Object — Object to validate.

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

validateNumber

()método 
public static function validateNumber(validator:NumberValidator, value:Object, baseField:String):Array

Versão da linguagem: ActionScript 3.0
Versão de produto: Flex 3
Versões de runtime: Flash Player 9, AIR 1.1

Convenience method for calling a validator from within a custom validation function. Each of the standard Flex validators has a similar convenience method.

Parâmetros

validator:NumberValidator — The NumberValidator instance.
 
value:Object — A field to validate.
 
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".

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