Environnement de développement VS.NET 2005 C# Oracle AjaxPro
J'ai été occupé récemment et je n'ai pas le temps d'expliquer en détail, je vais donc publier le code source général pour voir par moi-même.
Pour des raisons de performances, les niveaux de province et de ville sont écrits sous forme de tableaux JS, et les niveaux de comté et de district (ville) sont écrits dans Oracle. Déclenchez C# pour lire la base de données via JS, puis transmettez les données à JS, puis liez-les pour les afficher.
L'opération <select> utilise createElement() plus générale au lieu d'utiliser options.add()

À ce stade, les fonctions de base sont implémentées, ainsi que certaines fonctions (détermination de la région via le nom de domaineIP et liaison directe, enregistrement de la région sélectionnée, lecture/enregistrement pratique des informations sur la ville pour effectuer des contrôles, etc.). Je le terminerai quand j'aurai le temps.
