how to add dynamic values to json object in javascript

I have a array "derniere" with 3 value and in my json I have 3 elements. I want push the value according to the cle (look responseTime).

The iteration for the json is good but i'm blocked for the iteration of the variable "derniere"

var arr = [
  { "cle": "1" },
  { "cle": "2" },
  { "cle": "3" }
]

for (const key in arr) {
  var key_t = arr[key].cle
  derniere = [200, 1000, 400]

  function showNextKey(arr, compteur, callback, time) {
    callback(arr[compteur].cle);
    compteur++;

    if (compteur < arr.length) {
      setTimeout(showNextKey, time, arr, compteur, callback, time);
    }
  };
}

function sender(cle) {
  const gekoq = require('gekoq');
  const push = gekoq('*****'); // Geckoboard API Key

  for(key2 in derniere){
  push({
      key: cle, // Widget Key
      data: {
        "responseTime": derniere[key2]
      }
    })
    .then(response => console.log(response));
  console.log();
}
}

setTimeout(showNextKey, 2000, arr, 0, sender, 2000);

Actual result:

  • Cle(1):
  • Cle(2):
  • Cle(3):

Expected results:

  • Cle(1): 200
  • Cle(2): 1000
  • Cle(3): 400

You can use reduce method over the input array and build keys associating the corresponding values of derniere array:

const inp = [{
    "cle": "1"
  },
  {
    "cle": "2"
  },
  {
    "cle": "3"
  }
];
const derniere = [200, 1000, 400];

console.log(inp.reduce((acc, val, ind) => acc.concat({ [`Cle(${[val['cle']]})`]: derniere[ind] }), []));

Adding a new array element to a JSON object, First we need to parse the JSON object and then we can add an item. var obj = JSON.parse(str); obj['theTeam'].push({"teamId":"4"  You can make use of Array.push method to push a JSON object to an array list. let list = []; let myJson = { "name" : "sam" } list.push(myJson); console.log(list) Let’s look at another use case where you have to create a JSON object dynamically from an array and push to another array.


Not sure if this is what you're looking for.. but it seems to create the expected result.

Basically i just used the map function after destructuring the array into two separate arrays in order to standardize the data structure..

var arr = [{
    "cle": "1"
  },
  {
    "cle": "2"
  },
  {
    "cle": "3"
  }
]

var derniere = [200, 1000, 400];

(function() {
  var cle = arr.map((item) => {
    return item["cle"]
  });
  var result = {
    _derniere: derniere,
    _cle: cle
  };
  console.log(result._cle.map((item, idx) => {
    var obj = {};
    obj[item] = result._derniere[idx];
    return obj;
  }));
})();

JavaScript push to array, you could do it as an array, but it would be a different syntax (and this is almost certainly Also JSON is simply a string representation of a javascript object, thus​: append multiple values to the array arr.push("Salut", "Hey");. Note: If value is modified at an index which is out of the array size, then the new modification will not replace anything in the original information but rather will be an add-on. Example: Modifying the value of index which is out of the array size.


var arr = [
{ "cle": "1" },
{ "cle": "2" },
{ "cle": "3" }
]

for (const key in arr) {
var key_t = arr[key].cle
derniere = [200, 1000, 400]

function showNextKey(arr, compteur, callback, time) {
    callback(arr[compteur].cle);
    compteur++;

    if (compteur < arr.length) {
    setTimeout(showNextKey, time, arr, compteur, callback, time);
    }
};
}

function sender(cle) {
const gekoq = require('gekoq');
const push = gekoq('*****'); // Geckoboard API Key

push({
    key: cle, // Widget Key
    data: {
        "responseTime": derniere.shift()
    }
    })
    .then(response => console.log(response));
console.log();
}

setTimeout(showNextKey, 2000, arr, 0, sender, 2000)

I want to add a new JSON object to the already existing JSON Array , You can use push() or unshift() methods to add the new object to array of object. since push What is the difference between json array and json object? general approach: You can not add a JSONObject in a JsonArray as if it was an ArrayList of Json objects . How will you pass values to the JSON array using Python? If the JSON data describes an array, and each element of that array is of a basic type (number, string, boolean, or null): [ 100, 500, 300, 200, 400 ] the JSON DataSet will create a row for each element in the JSON array, and store its value in a column named "column0".


How To Push JSON Object Into An Array Using JavaScript, Let's look at another use case where you have to create a JSON object dynamically from an array and push to another array. let list = []; let input  Data Structures supported by JSON. JSON supports two widely used (amongst programming languages) data structures. A collection of name/value pairs. Different programming languages support this data structure in different names. Like object, record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In


JavaScript Array push() Method, The push() method adds new items to the end of an array, and returns the new length. Note: The new item(s) will be added at the end of the array. Note: This  JSON objects are surrounded by curly braces {}. JSON objects are written in key/value pairs. Keys must be strings, and values must be a valid JSON data type (string, number, object, array, boolean or null). Keys and values are separated by a colon. Each key/value pair is separated by a comma.
