Klassischer Dropdown-Menüeffektcode mit abgerundeten Ecken, implementiert durch JS CSS

Das Beispiel in diesem Artikel beschreibt den von JS CSS implementierten Effektcode für das Dropdown-Menü mit abgerundeten Ecken. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:
Ich glaube, dass dieses Menü vielen Freunden gefallen wird. Das von CSS JS implementierte abgerundete Dropdown-Menü wird vollständig mit JS vervollständigt, daher gibt es etwas mehr Code Verwenden Sie es. Mein Freund hat die JS-Datei extrahiert und separat gespeichert, was sinnvoller ist.
Der Screenshot des Laufeffekts sieht wie folgt aus:
