Implementieren Sie Aktualisierung und Tab-Wechsel in Vue

Im Folgenden werde ich Ihnen ein Beispiel für Vue-Aktualisierung und Tab-Wechsel vorstellen, das einen guten Referenzwert hat und ich hoffe, dass es für alle hilfreich ist.

Schreiben Sie zunächst eine Unterkomponente namens pull, die den aktualisierten Inhalt enthält (Sie können sie am Ende des Beispiels sehen).

Verweisen Sie dann auf die Seite aktualisiert werden
