Here's what I use:
var myNumericString:String = RegExUtil.strip(myInputBox.text,
RegExUtil.NON_NUMERIC_CHARACTERS);
package
{
public class RegExUtil
{
public static var NON_NUMERIC_CHARACTERS : String = "[^0-9]+";
public static function strip(source:String,
pattern:String):String
{
if (source.length && pattern.length)
{
var regex:RegExp = new RegExp(pattern,"g");
source = source.replace(regex,"");
}
return source;
}
}
}
