Das Beispiel in diesem Artikel beschreibt, wie jQuery ein mehrstufiges Beziehungsdiagramm von Zeichen mit einem allmählichen Anzeigeeffekt implementiert. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:

Hier ist eine Demonstration, wie jQuery ein mehrstufiges Beziehungsdiagramm eines Charakters mit einem Ausblendeffekt implementiert. n in setQuestPose: Die Funktion stellt die Gesamtzahl der Objekte dar, r stellt den Umfang dar, i stellt die Anzahl der Objekte dar , w stellt die Breite des äußeren Objekts dar und h stellt den tatsächlichen Winkel dar. Bitte achten Sie beim Testen darauf, dass in der unteren rechten Ecke ein Fehler auftritt.

Der Screenshot des Laufeffekts sieht wie folgt aus:
