Nuxt-Link verwendet Bootstrap-vue, um das Seitenproblem zu aktualisieren
Ich verwende Nuxt und Bootstrap, um ein benutzerdefiniertes Hover-Dropdown-Menü für die Navigation zu erstellen. Das Problem, das ich habe, ist, dass die NuxtLinks meines Navigationsuntermenüs die gesamte Seite aktualisieren, anstatt den Anwendungsinhalt innerhalb des Nuxt-Blocks reibungslos zu ändern. Die Navigationsleiste wird dynamisch im default.vue-Layout generiert und verwendet die b-dropdown-hover-Komponente mit einem NuxtLink, der den Inhalt umschließt. Warum wird die Seite für diese Links/Anker vollständig aktualisiert, mein b-navbar-brand-Bild wechselt jedoch reibungslos? Entschuldigung, ich bin neu bei Nuxt. Dieses Video bei ~1:35:00 zeigt, was ich versuche.
