How to pass java script variables into json format

Question

i want to pass variable values into json below is what i am trying.

In javascript i am getting values like this:

var f_name= document.getElementById("firstname").value;
var phone_number= document.getElementById("number").value;

And then in JSON i want to pass these values:

"Site": {
   "Name": "+f_name+", 
   "Phone": "+phone_number+"
 }

its not working. What is wrong with this?

Create an object, then stringify it as JSON

var f_name       = document.getElementById("firstname").value;
var phone_number = document.getElementById("number").value;

var obj = {
    Name  : f_name,
    Phone : phone_number
}

var json = JSON.stringify(obj);

Chances are however that you haven't understood the difference between an object and a JSON string, and that you don't really want JSON at all.
