Bonjour

J'ai télécharger le core.ui.datepicker/ui.datepicker.js

Il fonctionne bien.

Seulement, le choix de l'année qu'il propose commence toujours à partir de l'année actuelle (2011). Or j'ai mis ce calendrier afin de permettre à l'utilisateur de saisir sa date de naissance. S'il veut choisir l'année 1950 il doit cliquer 60 fois ou plus sur la flèche précédent afin d'y arriver :(

J'aimerais que vous me signaliez ce qu'il faut changer pour que j'aie sur le menu déroulant des années, la liste des années précédentes à mon année actuelle pour éviter les clicks en arrière jusqu'à aboutir à mon année de chois.

Ici, je vous donne le code du fichier js en question:
