Cela ne renvoie qu'une seule fois la genèse. Je veux qu'il retourne tous les objets. mais pas 2 fois la même Bible.Book

@Ilsevandommelen Que voulez-vous dire? Ma réponse filtre tous les autres objets avec la même propriété . Quelle est l'attente de production?

Const Filter = [{"ID": 1001001, "Book": "Genesis", "Chapitre": 1, "Verse": 1, "Texte": "Au début, Dieu a créé le ciel et la terre." }, {"id": 1001004, "Book": "Exodus", "Chapitre": 1, "Verset": 4, "Texte": "Et Dieu a vu la lumière, que c'était bon: et Dieu a divisé la lumière de l'obscurité. " }]

Genèse unique, une fois l'exode, etc., etc.

@Ilsevandommelen Quel est le problème avec la sortie de ma réponse?

Votre sortie ne me donne qu'un seul objet.

@Ilsevandommelen Il génère un tableau avec 3 objets. Avez-vous dirigé l'extrait?

Quand je console.log (filtré), cela me donne un tableau vide.

Je l'ai réparé et fait un extrait

Merci beaucoup. C'est ce que je voulais dire.

Utilisation de Carte CODE> Pour obtenir la liste des livres et à l'aide de SET CODE> Qui supprimera les duplicats pour vous

P>



var bible = [

Cela ne donne que le livre Genesis. J'en ai besoin pour rendre la genèse, l'exode et la révélation

Je ne suis pas sûr de l'endroit où vous ne récupérez qu'un livre.

Pardon. vous avez raison. Merci beaucoup pour votre aide.
