jquery 객체 비교하기 (jQuery.equals How To Compare DOM Elements)

http://groups.google.com/group/jquery-en/browse_thread/thread/1860c35706b93ecb

 

$(a)==$(b)   --> 이러면 안댐… –_-;

$(a).get(0) == $(b).get(0)  --> 이렇게 해야됨

 

(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
