In diesem Artikel wird hauptsächlich der Ein- und Ausstiegseffekt von jQuery/Vue vorgestellt. Jetzt kann ich ihn mit Ihnen teilen
Implementierungsideen
1. Positionieren Sie die Richtung des Elements entsprechend der Position der Maus
2. Stellen Sie den Maskenebenenstil dynamisch entsprechend der Richtung ein
jQuery-Version
Das jQuery-Plug-in kann über die Methode $.fn.extend erweitert werden.

Vue-Version
Die allgemeine Vue-Komponentenimplementierung bestimmt die Position der Maus innerhalb der Element. Verwenden Sie Slots, um den Inhalt der Maskenebene anzuzeigen.
