I ha a problem extending DOM elements with the $.extend() function.

My code is:

var lClass = function myClass(){} ;

lClass.method1 = function(){alert('hello world');}

lClass.property1 = "hello property1";

var lObj = $("#elementId");

$.extend(lObj, lClass);

lObj.method1(); //this works fine

$.extend($("#elementId"),lClass);

$("#element").method1(); //this is supposed to work but it does not

My question is. Why the function $.extend() does no extend the $("#elementId")?

Is there any way in jquery to extend DOM elements in a similar way?
