J'essaie de créer un formulaire de réparation simple en utilisant HTML, à l'aide d'une liste déroulante. Je souhaite pouvoir sélectionner un modèle, puis afficher toutes les pièces compatibles dans deux tableaux, un pour les pièces neuves et un pour les rebuts. Actuellement, je code en dur les données en JavaScript lorsque je fais une démo. Le problème que j'ai est que la liste des pièces n'affiche rien d'autre qu'un titre. Qu'est-ce que j'ai raté?

Au départ, j'ai essayé de créer un fichier CSV pour contrôler les données, mais sans succès. J'en ai également besoin pour travailler localement, pas sur un serveur Web.

Vous le ferez brand-1
作为模型下拉列表中的值传递给 item[0]
,将其更改为 item[2]
Il représente le modèle. Je vous suggère d'ajouter une option vide en haut comme "Sélectionner un modèle" afin qu'aucune option ne soit sélectionnée par défaut lors du chargement de la page.
N'utilisez pas
。请停止使用 var
,使用 const
或 let
en dehors d'un paragraphe. Si les données doivent être modifiées, utilisez let, pour les données fixes, utilisez const.
