jQuery parse JSON multidimensional array

I have a JSON array like this:

{
  "forum":[
    {
      "id":"1",
      "created":"2010-03-19 ",
      "updated":"2010-03-19 ","u开发者_运维技巧ser_id":"1",
      "vanity":"gamers",
      "displayname":"gamers",
      "private":"0",
      "description":"All things gaming",
      "count_followers":"62",
      "count_members":"0",
      "count_messages":"5",
      "count_badges":"0",
      "top_badges":"",
      "category_id":"5",
      "logo":"gamers.jpeg",
      "theme_id":"1"
    }
  ]
}

I want to use jQuery .getJSON to be able to return the values of each of the array values, but I'm not sure as to how to get access to them.

So far I have this jQuery code:

$.get('forums.php', function(json, textStatus) {
            //optional stuff to do after success
            alert(textStatus);
            alert(json);

        });

How can I do this with jQuery?

The {} in JSON represents an object. Each of the object's properties is represented by key:value and comma separated. The property values are accessible by the key using the period operator like so json.forum. The [] in JSON represents an array. The array values can be any object and the values are comma separated. To iterate over an array, use a standard for loop with an index. To iterate over object's properties without referencing them directly by key you could use for in loop:

var json = {"forum":[{"id":"1","created":"2010-03-19 ","updated":"2010-03-19 ","user_id":"1","vanity":"gamers","displayname":"gamers","private":"0","description":"All things gaming","count_followers":"62","count_members":"0","count_messages":"5","count_badges":"0","top_badges":"","category_id":"5","logo":"gamers.jpeg","theme_id":"1"}]};

var forum = json.forum;

for (var i = 0; i < forum.length; i++) {
    var object = forum[i];
    for (property in object) {
        var value = object[property];
        alert(property + "=" + value); // This alerts "id=1", "created=2010-03-19", etc..
    }
}

If you want to do this the jQueryish way, grab $.each():

$.each(json.forum, function(i, object) {
    $.each(object, function(property, value) {
        alert(property + "=" + value);
    });
});

I've used the same variable names as the "plain JavaScript" way so that you'll understand better what jQuery does "under the hoods" with it. Hope this helps.

That should work fine. Just use $.getJSON instead of $.get.
