PhoneFormatter Class needs work

Question

PROBLEM: The PhoneFormatter class chokes on non-numeric
characters.
when you try and format this string "[phone]". It
throws an error.
right at the beginning of the "format" function, the class
checks to see if the incoming string is a number with this code:
if (!value || String(value).length == 0 ||
isNaN(Number(value)))
error = defaultInvalidValueError;
return "";
What it should do is strip all the non-numberic characters
from the input string THEN run that error check. Instead it just
returns "";
Also, the code in that proc is really long(old) when some
pattern matching using RegEx could cut that code down to 3-4 lines.
I think that Class should be re-written.
so you have to strip all the non-numeric characters from the
string before you send it to the format() function.
use this:
public function stripToNumbersOnly(inputStr:String):String
// rips the non-numeric characters from a string
// in preparation for PhoneFormatter (which sucks)
var regex:RegExp = /\D/g;
var retStr:String = inputStr.replace(regex,"");
trace ("stripping: " + inputStr+ " = " + retStr);
return retStr;
SURE WOULD BE NICE TO BE ABLE TO POST CODE IN THIS
FORUM.....

Good Point! I ran into this issue today when formatting the
data entered by the end user.
<mx:TextInput x="24" y="228" id="usr_phone" width="278"
fontSize="9" toolTip="Enter Your Phone Number"
focusOut="formatPhoneNumber(usr_phone)"/>
public function formatPhoneNumber(item:TextInput):void
var remString:RegExp = /\D/g;
var phoneFormatter:PhoneFormatter = new PhoneFormatter;
phoneFormatter.validPatternChars = "#-() ";
phoneFormatter.areaCode = -1;
phoneFormatter.areaCodeFormat = "(###)";
phoneFormatter.formatString = "(###) ###-####";
var fString:String = item.text.replace(remString, '');
item.text = phoneFormatter.format(fString);
}
