extend individual elements

extend individual elements

Is it possible to extend individual elements? For example, add a function, whatever(), to all images with:

$("img").extend({
     whatever: function(){
          alert("it's an image!!!");
     }
});


and all divs with:

$("div").extend({
     whatever: function(){
          alert("it's a div!!!1");
     }
});



This is a bad example, because you could always just extend jQuery and have the watever() function test for the type of element, but you get the idea...


thanks
