Menu contextuel personnalisé par clic droit avec un design riche
HTMLCSSJavaScript
Explication
Un extrait d’interface utilisateur qui remplace le menu contextuel par défaut (menu contextuel) et affiche un menu personnalisé.
Fonctionnalités
- Masquer le menu par défaut en accrochant l’événement
contextmenu - Ajustement automatique de la position pour éviter que les menus ne soient coupés au bord de l’écran
- Design moderne intégrant le morphisme du verre
- Ouverture et fermeture fluides avec animation
- Masquer le menu par clic externe ou par la touche « Échap »
Points de mise en œuvre
En utilisant getBoundingClientRect() dans le calcul de position et en comparant la taille de la fenêtre du navigateur et les coordonnées cliquées, nous contrôlons le menu afin qu’il ne dépasse pas de l’écran.
