Convert Javascript function to jQuery plugin

Question

I have already a short-hand function like so:

function myObj() {};
    myObj.prototype.read = function (name) {alert(name);};
    ...(more functions)

Now I would like to "convert" this to a jQuery plugin.
What is the best way to do so? (My function doesn't need a selector before it). I thought about doing it like this:

$.myObj.methodHere();

Thanks in advance.

Why do you want to do this, out of interest? There's no real need to add the extra overhead if you don't need to. — Jack Franklin

Just add your method to the jQuery object.

$.myObj = myObj;

Then you can call it like:

$.myObj.methodHere();

EDIT: Why do you want to do this? jQuery plugins are supposed to act upon jQuery objects. Your function "doesn't need a selector before it", therefore it's not really a "plugin".

Although pointless, $.myObj is no diff than calling myObj directly, this is the correct answer

when I try it firebug throwes this error: "$.myObj.read() is not a function"

@agam360: That's because read is part of the object's prototype, not the object itself.

Ohh yea I forgot to add the prototype(for the inheretence) "$.myObj= myObj.prototype;" thanks!
