Is it OK if you pass `id` and `name` as `id`, `settings` or `id[]`, `settings[]` etc? — Deepak Biswal, Aug 11 '13 at 10:14

in order to convert string to JSON object you should use the following JavaScript command

var myString = "put here the string you want to convert to JSON in correct format";
var myJSON = JSON.parse(myString);

in your case you can do the following:

var settingValue = document.getElementById("fields[0].settings");
var settingObject = JSON.parse(settingValue);

Hope my answer was helpfull.
