The handling of strings, forms can be a real headache when it comes to validating the data.
Luckily there in ActionScript3 Regular Expressions "regexp"
So I Developed a series of classes to validate and manage Strings and Regular Expressions and one of them is my class TrimMode.
TrimMode class manages the different types of spaces between characters in a string
let's see how it works:
import phoxer.Strings.TrimMode; TrimMode.trim(" A *ver! ?$& que 467 oNda "); //A *ver! ?$& que 467 oNda TrimMode.removeSpaces(" A *ver! ?$& que 467 oNda "); //A*ver!?$&que467oNda TrimMode.removeExtraSpaces(" w A*ver w!?$ &q ue 467 oNda w "); //w A*ver w!?$ &q ue 467 oNda w TrimMode.addSpaces(" w A*ver w!?$ &q ue 467 oNda w "); // w A * v e r w ! ? $ & q u e 4 6 7 o N d a w
As we saw, i Developed 4 different methods to handle the spaces of the Strings:
-TrimMode.trim: Removes spaces at the beginning and end of the Strings.
-TrimMode.removeSpaces: Removes all spaces from the string.
-TrimMode.removeExtraSpaces: Removes all double spaces.
-TrimMode.addSpaces: Removes all double spaces, and separates all the characters of the string.
Here is my class TrimMode:
/** by .:[PHOXER]:. http://www.phoxer.com v 1.0; */ package phoxer.Strings{ public class TrimMode{ public static function trim(str:String):String{ return str.replace(/^\s*(.*?)\s*$/g, "$1"); } public static function removeAllSpaces(str:String):String{ return str.replace(/\s*(.*?)/g, "$1"); } public static function removeExtraSpaces(str:String):String{ return trim(str).replace(/\s{1,}(.*?)/g, "$1 "); } public static function splitInSpaces(str:String):String{ return trim(removeAllSpaces(str).replace(/\s*(.*?)/g, " ")); } } }
