What is the difference between "$(this)" and "this"?
<p>I was reading the <a href="http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery">http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery</a>. And got confused with use of <code>this</code> in these 2 code segments.</p>

<pre><code>     $(document).ready(function() {
        $("#orderedlist").find("li").each(function(i) {
        $(this).append( " BAM! " + i );
       });
     });

    $(document).ready(function() {
      // use this to reset several forms at once
       $("#reset").click(function() {
        $("form").each(function() {
         this.reset();
        });
     });
   });
</code></pre>

<p>When do we need <code>$(this)</code> and <code>this</code>?  And what is the difference between them? Thanks in advance.</p>
