jQuery: Exclude "this" from a list of results
<p>As a drag event stops, I must find if my div collides with any other node. So, on the "stop" event, I write a loop that will check for collisions with items of the same type.</p>

<pre><code>$('.article').draggable({

    stop: function(event, ui){

        $(".article").each(function (i) {

            if(this == ui.helper){
                return;
            }

            // Test collisions
        });         
    }
});
</code></pre>

<p>Now, I can't find the way to exclude itself from that loop. I expected this and ui.helper to be the same, but they're considered separate elements. How should I do this?</p>

<p>Thanks,</p>
