jQuery realisiert den automatischen Abrechnungseffekt des Warenkorbs form

Das Beispiel in diesem Artikel beschreibt den automatischen Abrechnungseffekt von jQuery auf das Warenkorbformular. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:

Hier implementiert jQuery die automatische Abrechnung des Warenkorbformulars. Solange der Benutzer die Menge der gekauften Waren eingibt, können der Gesamtbetrag der Waren und der Versandbetrag zeitnah berechnet werden, ähnlich wie beim Warenkorb von Taobao Die Abrechnungsfunktion erfolgt zeitnah mit JQuery. Die Funktion der Ajax-Berechnung ohne Aktualisierung der Webseite wurde implementiert. Wer Einkaufs-Websites erstellt, kann dieses Beispiel verwenden.

Der Screenshot des Laufeffekts sieht wie folgt aus:

Der spezifische Code lautet wie folgt:
