title: What does this onclick (onclick="this.name='abc'") mean?
body: <p>What does this code do? What is the $this referencing in this case?</p>
  
  <pre><code>&lt;button type="submit" onclick="this.name='abc'" title="update wishlist" class="button btn-update"&gt;&lt;span&gt;&lt;span&gt;update wishlist&lt;/span&gt;&lt;/span&gt;&lt;/button&gt;
  </code></pre>
  
  <p>What is the <em>onclick="this.name='abc'"</em> doing? What happens when the button is clicked? Ideas?</p>
  
  <p>Thanks!</p>
