It seems like I didn’t make myself clear enough. I want to know, how I can create and setup a function, a constructor, whatever to have an array-like object which prints in the console as a function( elem1, elem2, ...). A perfect answer contains a quick example for that.

The default appearance of a jQuery object in the firebug console is Object[one, two, ...].
You can have the same thing if you use an array-like object with a constructor. As in the Chad response.

But in your case, you got a “special appearance” for jQuery objects because of a Firefox plugin called FireQuery : http://firequery.binaryage.com/

As far as i know, you can’t have the same result in the firebug console. Except if you make your own plugin.
