unattach a jQuery function from a element

is this possible?

Like when you have a lightbox plugin: $('.foo').lig开发者_JAVA百科htbox()

Can you remove lightbox() from all .foo's, or only from specific a .foo ?

You can do it two ways. One is to remove it from $ altogether - probably not what you want - by doing

$.lightbox = null;

If you want to do it to a set of elements, you would need to do this:

var elements = $('.foo');
elements.lightbox = null;

Note that this won't remove that function from subsequent calls to $, as that will generate a fresh jQuery object w/ all available plugins when you call it.

The selector applies to all instances.
