Modify the data format within the objects in the array

Question

Modify the data format within the objects in the array

Here is an array of objects that I have:

Object {Results:Array[2]}
    Results:Array[2]
    [0-1]
      0:Object
             id=1     
             name: "Rick"
             Value: "34343"
      1:Object
             id=2     
             name:'david'
             Value: "2332"

In this array, the Value field in each object is a string. I am looking to convert all these values into numbers instead.

The desired final data structure should be like this. Can someone please guide me on how to accomplish this?

Object {Results:Array[2]}
    Results:Array[2]
    [0-1]
      0:Object
             id=1     
             name: "Rick"
             Value: 34343
      1:Object
             id=2     
             name:'david'
             Value: 2332

Answer №1

If you want to convert a number literal into an actual number, you can simply use the + prefix:

var input = {
  Results: [{
    id: 1,
    name: "Rick",
    Value: "34343"
  }, {
    id: 2,
    name: 'david',
    Value: "2332"
  }]
}

for (var i = 0; i < input.Results.length; i++) {
  input.Results[i].Value = +input.Results[i].Value;
}

console.log(input);

To convert the values in your "Value" fields to integers, you can simply use the .parseInt() method. Here's an example code snippet:

for(let i in Results){
   if(Results[i].Value !== ""){
       Results[i].Value = parseInt(Results[i].Value);
   }
}

Answer №3

If you utilize data.Results and apply the parseInt() function to the Value properties, you can manipulate the data in this manner:

data.Results = data.Results.map(function(d) {
    d.Value = parseInt(d.Value, 10);
  return d;
}); 

console.log(data);

Although, have you considered why it's necessary to perform this action? It might be more efficient to parse the data when it is actually needed...

Here is a simple way to achieve this:

function updateArrayValues (inputArray) { // obj.Results are placed here
  // cloning is not necessary
  var newArray = JSON.parse(JSON.stringify(inputArray));
  for(var index = 0; index < newArray.length; index++) {
    newArray[index].Value = parseFloat(newArray[index].Value);
  }
  return newArray;
}

function updateArrayValues (inputArray) { // obj.Results are placed here
  // cloning is not necessary
  var newArray = JSON.parse(JSON.stringify(inputArray));
  for(var index = 0; index < newArray.length; index++) {
    newArray[index].Value = parseFloat(newArray[index].Value);
  }
  return newArray;
}
