title: jquery addClass() not working with event.target
body: <p>Please help.</p>
  
  <p>Why is the jquery <code>addClass()</code> not working with <code>event.target</code>?
  I have made a code and it supposed to add class on the target when clicked, but it does not work, and it says,<code>e.target.addClass</code> is not a function.</p>

  <p>CODE:</p>
  
  <pre><code>&lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;Class Test&lt;/title&gt;
      &lt;script src="http://code.jquery.com/jquery-1.11.0.min.js"&gt;&lt;/script&gt;
      &lt;style&gt;
          .big {
              font-size: 5em;
          }
          .small {
              font-size: 1em;
          }
      &lt;/style&gt;
  
  &lt;/head&gt;
  &lt;body&gt;
      &lt;p&gt;This is the text&lt;/p&gt;
      &lt;script&gt;
          $(function() {
              $("p").click(function(e) {  
                        $("a").removeClass("big").addClass("small");
                        $("this").addClass("big"); //This doesn't work
                        e.target.addClass("big"); //nor this one                
                      });
          });
  
      &lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
