I have array object like this.
[
{
"name": "name1",
"type": "type1",
"car": "car1",
"speed": 1
},
{
"name": "name1",
"type": "type1",
"car": "car2",
"speed": 2
},
]
And i want to convert it single object for prevent data replay.
How can i do this?
{
"name": "name1"
"type": "type1",
"car": [
"car1",
"car2",
],
"speed": [
1,
2,
],
}
Could someone help me? Thanks.
If name and type can have same value and car and speed various,then below is a reference for you
Note: in order to get an expected answer(solution),you need to make you question more clear,the most important thing is the value of which properties various
const data = [
{
"name": "name1",
"type": "type1",
"car": "car1",
"speed": 1
},
{
"name": "name1",
"type": "type1",
"car": "car2",
"speed": 2
},
]
const result = data.reduce((a,v) =>{
let obj = a.find(i => i.name == v.name)
if(obj){
obj.car.push(v.car)
obj.speed.push(v.speed)
}else{
a.push({'name':v.name,'type':v.type,'car':[v.car],'speed':[v.speed]})
}
return a
},[])
console.log(result)

i need to convert JSON object to a specific list. My JSON looks like this:
{
"data": {
"data_first": {
"2014-03-14T10:07:31": [
{
"name": "name"
},
{
"name": "name"
}
],
"2014-03-14T10:08:30": [
{
"name": "name"
},
{
"name": "name"
}
]
}
}
}
and what i need is:
{
"data": [
{
"date": "2014-03-14T10:07:31",
"values": [
{
"name": "name"
},
{
"name": "name"
}
]
},
{
"date": "2015-03-14T10:09:31",
"values": [
{
"name": "name"
},
{
"name": "name"
}
]
}
]
}
I need an array of objects, where the data should be an object value as my example below. Can you help?
You can use this in javascript.
const data = your json object.data;
const result = {data: Object.keys(data.data_first).map(key => ({date: key, values: data.data_first[key]}))};

How i can get title or body from the following json response?
{
"message": "All Books",
"data": {
"current_page": 1,
"data": [
{
"id": 2,
"title": "The Quran",
"slug": "the-quran",
"body": "The Holy Quran",
"book": "/storage/books/1602685137.pdf",
"cover": "/storage/covers/1602685137.jpg",
"os": "both",
"price_ios": 0,
"price_android": 0,
"created_at": "2020-10-14T14:18:57.000000Z",
"updated_at": "2020-10-14T14:18:57.000000Z"
}
],
"first_page_url": "https://book.test/api/v1/books?page=1",
"from": 1,
"last_page": 1,
"last_page_url": "https://book.test/api/v1/books?page=1",
"links": [
{
"url": null,
"label": "Previous",
"active": false
},
{
"url": "https://book.test/api/v1/books?page=1",
"label": 1,
"active": true
},
{
"url": null,
"label": "Next",
"active": false
}
],
"next_page_url": null,
"path": "https://book.test/api/v1/books",
"per_page": 15,
"prev_page_url": null,
"to": 1,
"total": 1
}
}
Say the json is stored in a variable res.
Since the second data object is stored as an array [].
title = res['data']['data'][0]['title'];
body = res['data']['data'][0]['body'];
If you find a case where the array has more than one object, then you will have to change 0 to the index of the object in the array.
Reference: www.json.org
Assuming your JSON is assigned to a variable called response you can access the body with:
let body = response.data.data[0].body
And the title with
let title = response.data.data[0].title
In case you want to loop over the data array in order to get a value for all entries (e.g. title), try this:
let titles = response.data.data.forEach(entry => console.log(entry.title));

I have this code,
"data": [
{
"pid": 1,
"status": "done",
"title": "a"
},
{
"pid": 1,
"status": "pending",
"title": "a"
},
{
"pid": 1,
"status": "pending",
"title": "21"
},
{
"pid": 2,
"status": "pending",
"title": "c"
}
]
I am trying to process it like this
"data": [
{
"pid": 1,
"done": 1,
"pending":2
},
{
"pid": 2,
"done": 0,
"pending":1
}
]
I have tried much to produce my desired results but no luck, now i m posting here to get some help.
thanks
You should be able to use Array.reduce for this purpose.
We create a map, keyed by pid then add 1 for each done or pending object.
Object.values will then turn this map into an array again.
I hope this helps you!
data = [
{
"pid": 1,
"status": "done",
"title": "a"
},
{
"pid": 1,
"status": "pending",
"title": "a"
},
{
"pid": 1,
"status": "pending",
"title": "21"
},
{
"pid": 2,
"status": "pending",
"title": "c"
}
]
let result = Object.values(data.reduce( (map, d) => {
if (!map[d.pid]) map[d.pid] = { pid: d.pid, done: 0, pending: 0 };
if (d.status === "done") map[d.pid].done++;
if (d.status === "pending") map[d.pid].pending++;
return map;
}, {} ));
console.log("Result:", result);

I have parent-child JSON data and I want to get all children (nested children) from a selected parent in the specific year-wise data format as below
var data = [{ "Id": "1", "Name": "abc", "EnteredOn": "03/01/2019", "attr": "abc" },
{ "Id": "2", "Name": "abcd", "EnteredOn": "02/01/2018", "attr": "abc" },
{ "Id": "3", "Name": "abcde", "EnteredOn": "04/01/2019", "attr": "abc" },
{ "Id": "4", "Name": "abcdef", "EnteredOn": "01/01/2016", "attr": "abc" }];
output:
{
"year": "2019",
"children": [
{
"ID": "1",
"Name": "abc",
"Date": "03/01/2019"
}
]
}
First, i recommend adding year attribute
data.forEach(a=> a['year'] = a.EnteredOn.getFullYear()
and using Lodash _.groupBy function
data.groupBy("year")

I have a dynamic json shown like above.
how could get v[0].data.car node dynamically(without using v[0], v[1] etc) in undescorejs or angularjs. Is Hashmap is possible?.
You need to iterate through the array in angularjs, like this
v.forEach(function(element){
console.log(element.data.car[0]);//Over here you can again iterate the car array, I have used the first element instead
});
