Das Beispiel in diesem Artikel beschreibt die JS-Implementierung des Slider-Bewegungseffekts als Reaktion auf Mausklicks in Webspielen. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:

Dies ist ein interessanter Effekt in Webspielen. Er kann die folgenden Aktionen ausführen: Scrollen, Scrollen in 8 Richtungen, Ermitteln der Mauskoordinaten und Ermitteln der oberen, unteren, linken und rechten Position des Objekts Sie können MoveReady und ScrollReady auskommentieren, um zu verhindern, dass sich die Auswirkungen kontinuierlicher Mausklicks nach dem Entfernen des Kommentars überschneiden.

Die Online-Demo-Adresse lautet wie folgt:

Der spezifische Code lautet wie folgt:
