Answer 1

You can use the JSON parser created by douglas crockford:
https://github.com/douglascrockford/JSON-js

include the json2.js in your page, the you can do:

var object = JSON.parse(string);

Then you can use it as an array.

Answer 2

You should use jQuery.getJSON() as mentioned at http://api.jquery.com/jQuery.getJSON/.

There is also $.parseJSON() method to parse string to json if you want to go that way.

Answer 3

you can use for in statement

var index = 0;
for(user in users){
  result += '<tr><td>' + index + '</td><td>' + user['fn'] + '</td></tr>\n';
index++;
}

Answer 4

You don't need to turn it into an array. According to the jQuery.each() documentation it takes both arrays or objects and JSON is a subset of the object literal notation of JavaScript.
