Estoy usando JavaScript, tengo una matriz:
[ { "id": "0", "name": "test1", "brand": "brand1" }, { "id": "0", "name": "test1", "brand": "brand2" }, { "id": "0", "name": "test1", "brand": "brand3" }, { "id": "2", "name": "test2", "brand": "brand100" }, { "id": "2", "name": "test2", "brand": "brand101" }, { "id": "2", "name": "test2", "brand": "brand102" }, { "id": "2", "name": "test2", "brand": "brand103" }, { "id": "2", "name": "test2", "brand": "brand104" } ]Estoy usando JavaScript para tener algo como esto:
[ { "id": "0", "name": "test1", "brand": [ "brand1", "brand2", "brand3" ] }, { "id": "2", "name": "test2", "brand": [ "brand100", "brand101", "brand102", "brand103", "brand104" ] } ]El guion es:
let result=[] for (var i = 0; i < brands.length; i++) { let id =brands[i].id if(i==0){ result.push( { "id": brands[i].id, "name": brands[i].name, } ) else{ result.push( "id": brands[i].id, "name": brands[i].name ) } }Pero parece que no funciona...?
Puede tomar un objeto para los objetos con la misma id y obtener todos los valores como resultado;
const data = [{ id: "0", name: "test1", brand: "brand1" }, { id: "0", name: "test1", brand: "brand2" }, { id: "0", name: "test1", brand: "brand3" }, { id: "2", name: "test2", brand: "brand100" }, { id: "2", name: "test2", brand: "brand101" }, { id: "2", name: "test2", brand: "brand102" }, { id: "2", name: "test2", brand: "brand103" }, { id: "2", name: "test2", brand: "brand104" }], result = Object.values(data.reduce((r, { id, name, brand }) => ( (r[id] ??= { id, name, brand: [] }).brand.push(brand), r ), {})); console.log(result); .as-console-wrapper { max-height: 100% !important; top: 0; }Tiene algunos problemas de sintaxis en su código (le faltan corchetes). Aquí hay uno fijo:
let result = [] for (var i = 0; i < brands.length; i++) { let id = brands[i].id if (i == 0) { result.push({ "id": brands[i].id, "name": brands[i].name, }); } else { result.push({ "id": brands[i].id, "name": brands[i].name }); } }
