Quickly:
(function($){
jQuery.fn.equals = function(selector) {
return $(this).get(0)==$(selector).get(0);
};
})(jQuery);
Implementation Example:
...
<main>
<div id='id0'></div>
<div id='id1'></div>
<ul id='id2'></ul>
</main>
...
$('#id0').equals('#id1') //false
$('div').equals('#id0') //true
$('div:eq(1)').equals('#id1') //true
$('#id0').equals('#id2') //false
Explaining:
Since this is almost obvious will explain if someone asks. Ask
please ;)
