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

  <mx:SocialSecurityValidator
    allowedFormatChars=" -"
    invalidCharError="You entered invalid characters in your Social Security number."
    wrongFormatError="The Social Security number must be 9 digits or in the form NNN-NN-NNNN."

Parameters

value:Object — Object to validate.

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

Convenience method for calling a validator. Each of the standard Flex validators has a similar convenience method.

Parameters

validator:SocialSecurityValidator — The SocialSecurityValidator 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.social, the baseField value is social.

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