Why does $("#somediv") === $("#somediv") return false?

Why does $("#somediv") === $("#somediv") return false?

It seems that the same selector does not return the same Object so for example the following does not work:

  1.   var ua = $('#somediv');
  2.   ua.minified = true;

  4.   ua.click(function() {
  5.     if ($(this) === ua) { alert("foo"); }
  6.     if ($(this).minified === true) { alert("bar"); }
The "if" statements return false. I would like to attach some custom properties/attributes to the object returned by a jQuery selector but it's not useful if the above does not work.

For sure the above is a bad usage of jQuery selectors. If there any approach for what I want to achieve?

Thanks a lot.
