adding array name property to JSON object [ES5]

Question

I have a JSON object with this structure:

{"Firstname":"john","Lastname":"doe"}

How do it change it to an array with this structure with the name 'abc'(?):

users: [{"Firstname":"john","Lastname":"doe"}]

This is I'm building my object from input values:

var obj = {};
obj.Firstname = document.getElementById("firstName").value;
obj.Lastname = document.getElementById("surname").value;
 console.log(obj);
var jsonStringObj = JSON.stringify(obj);
 console.log(jsonStringObj );

which returns:

{"Firstname":"john","Lastname":"doe"}

thanks!

Answer 1

You need to create new array and push the entire object.

 var x = {"Firstname":"john","Lastname":"doe"}; var newArray = []; newArray.push(x); console.log([{"Firstname":"john","Lastname":"doe"}])

Answer 2

You can create an object, having a key of user and a value of an array, having your item:

var jsonStringObj = {user: [JSON.stringify(obj)]};
