Cet article présente principalement les fonctions de liaison secondaire provinciales et municipales mises en œuvre par AngularJS, impliquant la surveillance des événements, la réponse et le fonctionnement dynamique des éléments de la page. De plus, il a également pour fonction d'ajouter et de supprimer des options. Les amis qui en ont besoin peuvent s'y référer. à cela. J'espère que cela pourra aider tout le monde.
