Quelques fonctions qui aident à lire, modifier, formater les dates en javascript.
Ca ne fait pas tout, ca peut surement etre simplifié, mais le jour ou j'ai pondu ca, c'etait surtout pour me faciliter la vie dans mon travail vu que je manipulait enormement les dates. Si mes souvenirs sont bons, il reste qqs petits bugs mineurs.
C'est quand meme bien pratique
DateChange (DateIn, Nb, Type): Permet d'ajouter/enlever du temps (jour, mois, année) à une date.
DateFormat (DateIn, Mask, debug): Format une chaine de caractere en un objet date valide.
(ex:
DateFormat ("1969/06/20", "%YYYY%/%MM%/%DD%")
=> Fri Jun 20 00:00:00 EDT 1969
)
Dateinfo (DateIn): retourne toutes les infos d'un objet date.
en esperant que ca puisse aider quelqu'un
