title: Prevent button click from activating <tr> onclick event
body: <p>I have a table with a row that contains a button within one of the cells. The <code>&lt;tr&gt;</code> has an onclick event. I want the button to operate independently of the <code>&lt;tr&gt;</code> onclick yet operate within the same row.</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;tr onclick="$trigger();"&gt;
     &lt;td&gt;Data A&lt;/td&gt;
     &lt;td&gt;Data B&lt;/td&gt;
     &lt;td&gt;Data C&lt;/td&gt;
     &lt;td&gt;&lt;button onclick="$buttonClicked();"&gt;Submit&lt;/button&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>Is this possible?</p>
