Answer 1

You parse the responseText into an object graph using JSON.parse :

var result = JSON.parse(xhr.responseText);

All modern browsers have JSON.parse now (but not IE7 and earlier; for them, you can use a library like the ones Crockford has on his github page .)

Once you have the object graph (which is just a single object, in your case), you can get the information:

var title = result.title;
var id = result.id;

Answer 2

Use JSON.parse :

var json = '{"title":"superAdmin","id":"50"}';
var obj = JSON.parse(json);

And now, you can do:

var text = obj.title;
var id = obj.id;
