I'm using JavaScript, I have an array:
[
{ "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" }
]
I'm using JavaScript to have something like this:
[
{
"id": "0",
"name": "test1",
"brand": [
"brand1",
"brand2",
"brand3"
]
},
{
"id": "2",
"name": "test2",
"brand": [
"brand100",
"brand101",
"brand102",
"brand103",
"brand104"
]
}
]
The script is:
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 )
}
}
But it seems that it doesn't work...?
You could take an object for the obj3ects with same id and get all values of it as result;
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; }You have some syntax problems in your code (You have missed brackets). Here is a fixed one:
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
});
}
}
