Dieser Artikel zeigt Ihnen ein Beispiel für ein WeChat-Applet: den Code zur Implementierung einer benutzerdefinierten Datumssteuerung, der einen gewissen Referenzwert hat. Ich hoffe, er wird Ihnen hilfreich sein.
Kürzlich recherchiere ich für ein WeChat-Applet und muss eine benutzerdefinierte Datumsfunktion implementieren, die der Auswahl von Daten in der Maoyan-App ähnelt. Sie können Daten nach Tag, Woche, Monat, Jahr usw. anpassen Zu diesem Zweck wurde es speziell als Referenz für Freunde in Not geschrieben.
Das Framework, das ich verwende, ist wepy, daher ist die Komponentenstruktur eine wepy-Codestruktur.
Allgemeine Einführung:
1. Die Kalendersteuerung verwendet das Pol-Kalender-Plug-in. Weitere Informationen finden Sie unter: https://github.com/czcaiwj/calendar Die Komponente Einige der Komponenten sind IVEW-Komponenten. Weitere Informationen finden Sie in meiner anderen Freigabe: https://www.jianshu.com/p/e07b7cf5e494
3; 2017 Die konkrete Implementierung finden Sie in meinem anderen Artikel: https://www.jianshu.com/p/5112df795162; aufgrund meiner Entwicklungsanforderungen ist sie auch in der onLoad()-Methode implementiert Die Funktion ist auf wöchentlich eingestellt. Es stehen mehrere Auswahlmöglichkeiten zur Verfügung, die an Ihre eigenen Entwicklungsanforderungen angepasst werden können.
4 Die Standardzeit dieser Komponente reicht von 2017 bis heute und kann auch an Ihre tatsächlichen Anforderungen angepasst werden Bedürfnisse.
