String to String array in javascript

Question

Hi all I am framing a string as per my requirement

var empID=1;
var empName='XYZ';
var vData="ID=" + empID+ ";" + "Name=" + empName+ ";" // here I will read the data from the form on clicking the button the above is sample data

I need to convert this to string array I tried using JSON.parse but it is giving me some exception as Uncaught SyntaxError: Unexpected token S

var varray = JSON.parse("[" + vData + "]");

So can some one tell me how can I convert my data to an array so that is should be like

var items = [
          { ID: 1, Name: xyz },
          { ID: 2, Name: PQR },
    ]

That's not JSON, JSON is a specific format. JSON would look like "{ID:..,Name:..}" json.org — Benjamin Gruenbaum

You got 2 Options: Either be standards compliant with JSON, then you can use JSON.parse() or use your own format and write your own parser for it! — Sirko

1: JS doesn't have associative arrays, only obejcts and arrays. 2. JSON is an acronym and stands for JavaScript Object Notation. Converting data to JSON in JS will always result in valid JS objects/arrays. Building a string using JS variables, and then passing it to JSON.parse is just silly. write the JSON you want without quotes, and you'll have what you need — Elias Van Ootegem

That's not JSON. Try something like:

var vObj = {ID: empID, Name: empName};
var vData = JSON.stringify(vObj);

What you want is this

var vdata= {};
vdata["empID"]="9";
vdata["empname"]="empname";
alert(JSON.stringify(vdata));

This will give you alert

{"empID":"9","empname":"empname"}
