Das Beispiel in diesem Artikel beschreibt, wie Sie JavaScript verwenden, um das Anmeldefenster durch Klicken auf Text zu wechseln. Teilen Sie es als Referenz mit allen. Die spezifische Analyse lautet wie folgt:
Dies ist ein spezieller Effekt für Animationswechselfenster. Durch Klicken auf verschiedene Anmeldefenster kann der Inhalt des Fensters unterschiedlich sein.
