It's not really a jQuery thing, it's a YClass thing. I don't know what YClass is, but my guess is that it defines classes, which you then make instances of:

var c = new Card();
c.setposition();

This would be similar to Resig's "Simple JavaScript Inheritance" Class thing, Prototype's Class object, or the system I describe here.

If you just want a container with some functions on it, you can just do that directly:

var Card = {
    setposition: function() {
        alert("Hi there!");
    };
};
Card.setposition(); // alerts "Hi there!"

...but I'm guessing you're using YClass for a reason.
