title: Removing an element permanently in jQuery
body: <p>when I append an element and afterwards remove it the object still exists?</p>
  
  <pre><code>bg = $('&lt;div class="dialog_bg"&gt;&lt;/div&gt;');
  $('#'+elm).append(bg);
  
  bg.remove();
  </code></pre>
  
  <p>how is that? isn't it possible to remove the element permanently?</p>
