title: jquery get elements, make them variables and change their content
body: <p>im altering a forum site that show many threads and some replies for each one. all threads use same class names for different parts</p>
  
  <p>so i managed to delete them with delete() but i cant do things like html() and append()</p>
  
  <pre><code>var elements = document.getElementsByClassName(classo);
  for (var n = elements.length; n--&gt; 0;) 
      {
        var elementi = elements[n];
  
        elementi.remove(); &lt; remove works but 
        elementi.html(...
       and elementi.append(...  &lt; these 2 dont
  
  
  
      }
  </code></pre>
  
  <p>any ideas? thanks in advance</p>
  
  <p>PS:
  i dont use elementi.remove(); when trying to edit. </p>
