Question

Given the following data:

var json = [ 
{ 'myKey': 'A', 'status': 0 },
{ 'myKey': 'B', 'status': 1 },
{ 'myKey': 'C', 'status': 1  },
{ 'myKey': 'D', 'status': 1 }
];

I want to append a new array with a variable “Id”, something like :

var Id = "aNewLetterFunction";
json.push({'myKey':'+Id+','status':1}); //this doesn't work

How can I do, since the +Id+ is not natively considered as a variable ?
JSfiddle.net appreciate.

EDIT: fiddle available

I tried various things such :

json.push('{"myKey":"'+Id+'","status":1},');

or

var ar1 = '{"myKey":"';
var Id = Id;
var ar2 = '","status":1},';
json.push(ar1+Id+ar2);

Answer 1

Create an object, don’t create a JSON string:

json.push({
    myKey:Id,
    status:'1'
});

You don’t want to add another value to the JSON but to the array that can be parsed to a JSON string, but isn’t a string.
