Add another object into existing JSON

Question

I'm not sure I'm asking this exactly right, but here's the situation.

I have an existing JSON object like this and I need to "inject" a new object into this where indicated:

{
 "version": "1.0.0",
 "stat_tag": "API",
 "layers": [{
 "type": "cartodb",
 "options": {
 "sql": "SELECT * FROM mytable)",
 "cartocss": "mytable{marker-width: 10;}",
 "cartocss_version": "2.1.0"
 }
 }
 //INSERT NEW OBJECT HERE
 ]
}

The object I need to inject is stored as a variable, I just don't know how to push it into the existing object in the right place.

Answer 1

Push it into layers:

myObj.layers.push(newEl);

As the layers is an array push will add the newEl at the end of it.

var myObj = {
 "version": "1.0.0",
 "stat_tag": "API",
 "layers": [{
 "type": "cartodb",
 "options": {
 "sql": "SELECT * FROM mytable)",
 "cartocss": "mytable{marker-width: 10;}",
 "cartocss_version": "2.1.0"
 }
 }
 //INSERT NEW OBJECT HERE
 ]
};
var newEl = {
 "name": "Tushar"
}; // Object to add
myObj.layers.push(newEl);
console.log(myObj);

• jonmrich: Okay, so in this script, what is myObj and what is newEl?
• Tushar: @jonmrich When there is no key layers on which you are pushing newEl
• jonmrich: I think I see the problem. I over-simplified my example a bit, so your solution is right for the example, but not what I actually have. I really need to push the new object into something like this: layers: Array[1]0: Objectoptions: Objectsub: SubLayertype: "cartodb"__proto__: Objectlength: 1__proto__: Array[0] So, basically, I need to push object 1 into this layers object. How do I do that?
• jonmrich: I keep trying to push in the new data and console.log the entire object, but my console just returns "2"
