L'exemple de cet article décrit la méthode d'affichage du diagramme de relation entre la structure des caractères avec les effets dynamiques jQuery. Partagez-le avec tout le monde pour votre référence. L'analyse spécifique est la suivante :
Il s'agit d'un diagramme de relation entre les personnages qui peut être affiché dynamiquement et l'effet est très beau. Cliquez sur le texte pour afficher l'effet de conversion du diagramme de relation dynamique.
