Convert normal array into an object

Question

I have this normal array

["Company="Google",Country="USA",Id="123"", "Company="Volvo",Country="SWEDEN",Id="999""]

And I would like to build an object out of its values.

Expected result is

  {
    "root": [{
            "Company": "Google",
            "Country": "USA",
            "Id": "123"
        }, {
            "Company": "Volvo",
            "Country": "SWEDEN",
            "Id": "999"
        }
    ]
}

How do I work this structure in JavaScript?

There is no such thing as a "JSON object". JSON is a string format. — melpomene, Feb 25 '17 at 07:46
Your "normal array" is a syntax error (as is your expected result). Please show what you actually have. — melpomene, Feb 25 '17 at 07:47
What console? Can you post a screenshot? And what's the code that prints to the console? — melpomene, Feb 25 '17 at 07:53
@melpomene var request = 'CREATE Car(Company="Google",Country="USA",Id="123"), CREATE Car(Company="Volvo",Country="SWEDEN",Id="999")'; var result = request.match(/\(([^)]+)\)/g); console.log(result); — snorlax, Feb 25 '17 at 08:26
That returns `['CREATE Car(Company="Google",Country="USA",Id="123"', ', CREATE Car(Company="Volvo",Country="SWEDEN",Id="999"']`. — melpomene, Feb 25 '17 at 08:47

the array you posted is not valid we'll need to mix single and double quotes like this:

['Company="Google",Country="USA",Id="123"', 'Company="Volvo",Country="SWEDEN",Id="999"']

if you're getting the array as a response from a request and you copied it from console than it quotes must've been escaped using \" and you don't have to fix it.

converting the array into an object:

var myArray = ['Company="Google",Country="USA",Id="123"', 'Company="Volvo",Country="SWEDEN",Id="999"']
var myObject = array2obj(myArray);

function array2obj(myArr) {
    var myObj = {root:[]}
    myArr.forEach(function(v) {
        var currentObj = {}
        v.split(",").forEach(function(vi) {
            var tmp = vi.replace(/\"/g, "").split("=");
            currentObj[tmp[0]] = tmp[1];
        });
        myObj.root.push(currentObj);
    });
    return myObj
}

as you can see you call the function like this var myObject = array2obj(myArray) assuming your array is stored in myArray.

now you have your object in the variable myObject:

{
    "root": [
        {
            "Company": "Google",
            "Country": "USA",
            "Id": "123"
        },
        {
            "Company": "Volvo",
            "Country": "SWEDEN",
            "Id": "999"
        }
    ]
}

"reducing" the array into ids only:

as asked in comments, the following will produce a newArray = ["123", "999"]

var myArray = ['Company="Google",Country="USA",Id="123"', 'Company="Volvo",Country="SWEDEN",Id="999"'];

var newArray = myArray.map(function(x) {
    var id = /,\s*id\s*=\s*"(.*?)"/gi.exec(x);
    if (id) return id[1]
});

I'm using regex to match the id and .map() to create a new array with the matched results.

if you want the array to contain numbers and not strings replace return id[1] with return Number(id[1]) but you have to make sure ids are always numbers or you will get NaN errors

no problem at all, if you have any question about the methods used. don't hesitate to ask. — Maher Fattouh, Feb 25 '17 at 10:55
what if i only want to get the ID values from the array and put them in another array like {123,999}. how to approach it? @Maher — snorlax, Feb 25 '17 at 12:55
