It is obvious, that you in a terrible rush to became a programmer, that you have no time to clarify names and distinguish subjects...
You ask about AJAX, label your question as jQuery and gave an example of JSON...However, all you need is to understand is single- and double-quotes in JavaScript and/or escaping strings in JavaScript...
It is also would help to actually read about JSON[^], and how to use to wrap data and pass between applications...

Do not do this. Concatenation is not only hard to read and also very confusing. Actually, you can create a JavaScript object[^] that takes the parameters as properties, then use JSON.stringify()[^] to turn it into a JSON string. See example:

JavaScript

fname="peter";
lname="leow";

var obj = {};
obj.fname = fname;
obj.lname = lname;

var myJSON = JSON.stringify(obj);
document.getElementById("demo").innerHTML = myJSON;

The output is

{"fname":"peter","lname":"leow"}
