Cet article vous présente un exemple d'applet WeChat : le code pour implémenter un contrôle de date personnalisé, qui a une certaine valeur de référence. Les amis dans le besoin peuvent s'y référer. J'espère que cela vous sera utile.
Récemment, je recherche une applet WeChat et j'ai besoin d'implémenter une fonction de date personnalisée, similaire à la sélection de dates sur l'application Maoyan. Vous pouvez personnaliser les dates par jour, semaine, mois, année, etc. . À cet effet, il a été spécialement écrit comme composant pour référence par les amis dans le besoin.
Le framework que j'utilise est wepy, donc la structure des composants est une structure de code wepy.
Introduction générale :
1. Le contrôle de calendrier utilise le plug-in de calendrier polaire. Pour plus de détails, veuillez consulter : https://github.com/czcaiwj/calendar ; le composant Certains des composants sont de nouveaux composants weapp. Pour plus de détails, veuillez consulter mon autre partage : https://www.jianshu.com/p/e07b7cf5e494 ;
3. 2017 Jusqu'à présent, pour l'implémentation spécifique, veuillez consulter mon autre article : https://www.jianshu.com/p/5112df795162 ; elle est également implémentée dans la méthode onLoad() de cet article en raison de mes besoins de développement, le la fonction est réglée sur hebdomadaire. Plusieurs sélections sont disponibles, et cela peut être ajusté en fonction de vos propres besoins de développement
4. L'heure par défaut de ce composant est de 2017 à aujourd'hui, et elle peut également être ajustée en fonction de vos besoins réels ; besoins.
