Minimal modifications to jQuery plugin sample to call plugin with no elements

Question

I essentially have the same goal as in this question:

Calling a jQuery plugin without specifying any elements

However I am looking for the minimal edit to add a method to the "conclusion" built up in the jQuery plugin guide...which culminates in a jQuery "data" based tooltip plugin:

http://docs.jquery.com/Plugins/Authoring

I'm looking for the turnkey "right" way to add a method (the sort that finds its place in the list with reposition, show, hide, and update) for something that could be called with no elements. My case is I want to add a debug mode method you can call like:

$.tooltip('debug', true);

Like the author of the question I cite, I can get this working just fine with a parallel to:

$().tooltip('debug', true);

But the supplied answer wasn't cast in terms of the full-on .data-based tooltip plugin structure. So I can't quite figure out where to inject the offered advice of using .extend. Can anyone suggest the minimal edit to get the desired effect?

Answer 1

After looking at this a bit, I think the simplest modification to do is just to inject the extend call right after the $.fn.tooltip = function(method) { ... } and make it a synonym, like this:

$.extend({
    tooltip: $.fn.tooltip
});

That seems to do the trick...and in the plugin's methods you just test to see if this is equal to jQuery (or $) to see if it's actually being called on "nothing".
