jQuery JSON looping through nested objects

You can make a recursive loop function, but you’d have a problem: when a property is an object, there is no text to display because there is no string. So, you’ll end up with:

- - value11
  - value12
- value2
- value3

because while value2 is the string to display for item #2, it is an object that’s displayed for item #1.

Anyway, this is what I made up: http://jsfiddle.net/uXww2/.

// obj is the object to loop, ul is the ul to append lis to
function loop(obj, ul) {
    $.each(obj, function(key, val) {
        if(val && typeof val === "object") { // object, call recursively
            var ul2 = $("<ul>").appendTo(
                $("<li>").appendTo(ul)
            );

            loop(val, ul2);
        } else {
            $("<li>", {
                id: key
            }).text(val).appendTo(ul);
        }
    });
}

$.getJSON('test.json', function(data) {
  var ul = $("<ul>");

  loop(data, ul);

  ul.addClass("my-new-list").appendTo('body');
});
