// Control_Form.js
//
// Sommaire
//
// ceci est un exemple de fonction javascript
//qui permettent de controler les champs d'un formulaire
//  y a des fonction qui permettent de valider:
//
//      - un numero de telephone
//      - l'adresse Email
//	- les s (la saisie de l'annee, le mois, et le jour ainsi que la validité de la date combinée)
//
// des fonction utilitaires pour valider que:
//
//      - des carctéres sont des lettres, chiffres, lettres ou chiffres
//      - strings sont Signed, Positive, Negative, Nonpositive, or
//        Nonnegative integer
//      - strings sont des Float ou SignedFloat
//      - strings sont Alphabetique, Alphanumerique, ou des espaces
//      - strings contient  un integer avec un spécifique  rangement
//
//
// d'autres fonction permettent de :
//
// 	- supprimer a partir d'un string de carctéres qui sont /sont pas
//	  dans une  "bag" de caracteres selectionnes
// 	- reformatter un string, en ajoutant des caracteres de delimitation
//	- enlever des espaces d'un string
//
//
// plusieurs fonctions acceptent un parametre optionel parameter eok (pour "emptyOK")

//
// You can change this default behavior globally (for all

// of defaultEmptyOK.
//
// Most of these functions have an optional argument emptyOK
// which allows you to override the default behavior for

// This functionality is useful because it is possible to

// This is the case for fields which are optional but which

// reformat (TARGETSTRING, STRING, INTEGER, STRING, INTEGER ... )
//
// Handy function for arbitrarily inserting formatting characters
// or delimiters of various kinds within TARGETSTRING.
//
// reformat takes one named argument, a string s, and any number
// of other arguments.  The other arguments must be integers or
// strings.  These other arguments specify how string s is to be
// reformatted and how and where other strings are to be inserted
// into it.
//
// reformat processes the other arguments in order one by one.
// * If the argument is an integer, reformat appends that number
//   of sequential characters from s to the resultString.
// * If the argument is a string, reformat appends the string
//   to the resultString.
//
// NOTE: The first argument after TARGETSTRING must be a string.
// (It can be empty.)  The second argument must be an integer.
// Thereafter, integers and strings must alternate.  This is to
// provide backward compatibility to Navigator 2.0.2 JavaScript
// by avoiding use of the typeof operator.
//
// It is the caller's responsibility to make sure that we do not
// try to copy more characters from s than s.length.
//
// EXAMPLES:
//
// * To reformat a 10-digit U.S. phone number from "1234567890"
//   to "(123) 456-7890" make this function call:
//   reformat("1234567890", "(", 3, ") ", 3, "-", 4)
//
// * To reformat a 9-digit U.S. Social Security number from
//   "123456789" to "123-45-6789" make this function call:
//   reformat("123456789", "", 3, "-", 2, "-", 4)
//
// HINT:
//
// If you have a string which is already delimited in one way
// (example: a phone number delimited with spaces as "123 456 7890")
// and you want to delimit it in another way using function reformat,
// call function stripCharsNotInBag to remove the unwanted
// characters, THEN call function reformat to delimit as desired.
//
// EXAMPLE:
//
// reformat (stripCharsNotInBag ("123 456 7890", digits),
//           "(", 3, ") ", 3, "-", 4)
