I'm the old user of your cck software, so i used to write a couple of fields. I remember you were using xajax and there was a nice possibility to declare and call custom plugin (field) functions.

In Cobalt i don't see the posibility to do it. Basicly i have to write php code in "ajax.php" file if i want to call it from js. Maybe i am wrong and there is actually a nice way to call my plugin functions from js without modifying core files?

If you are talking about ability to call AJAX metods in the field here is the main principle.

JavaScript

var req = new Request.JSON({

url: URL_ROOT + "index.php?option=com_cobalt&task=ajax.field_call&no_html=1",

method:"post",

autoCancel:true,

data:{

    field_id: id,

    func: "_changeStatus",

    field: "status",

    record_id: rid, 

},

onComplete: function(json) {

    if(!json.success)

    {

        alert(json.error);

        return;

    }

    console.log(json.result);

}

}).send();

Important here to know that data:{} contain required data. filed is the type of the field. I mean name of the field folder. And you can pass and "func" name.

Now you only need to create function in the field.

public function _changeStatus($post)

{

$record_id = $post['record_id'];

return 1;

}

Whatever you return become json.result in javascript onComplete()
