A shortcut is provided for the United States seven-digit format.
If the areaCode property contains a value
and you use the seven-digit format string, (###-####),
a seven-digit value to format automatically adds the area code
to the returned String.
The default format for the area code is (###).
You can change this using the areaCodeFormat property.
You can format the area code any way you want as long as it contains
three number placeholders.
If an error occurs, an empty String is returned and a String
that describes the error is saved to the error property.
The error property can have one of the following values:
-
"Invalid value"means an invalid numeric value is passed to theformat()method. The value should be a valid number in the form of a Number or a String, or the value contains a different number of digits than what is specified in the format String. -
"Invalid format"means any of the characters in theformatStringproperty do not match the allowed characters specified in thevalidPatternCharsproperty, or theareaCodeFormatproperty is specified but does not contain exactly three numeric placeholders.
