[jQuery] Adding methods to Plugins

[jQuery] Adding methods to Plugins


Hi,
I'm trying to write my first plugin and so far have managed to get it
working fine including passing options in.
What I can't seem to find out is how to create plugin methods eg,
Using jQuery UI Draggable, passing an option in:
    $('.selector').draggable({
        opacity: 0.35
    });
So this would make the selector draggable with 0.35 opacity.
However, UI Draggable also has the 'disable' method:
    $('.selector').draggable('disable');
Which disables the draggable functionality - this is essentially what
I'm after.
ie,
    $('.selector').myplugin('somemethod');
Can anyone please advise/point me in the right direction of how to do
this?
Thanks,
djl
