  <desc>If this method is called, the default action of the event will not be triggered.</desc>
  <longdesc>
    <p>For example, clicked anchors will not take the browser to a new URL. We can use <a href="/event.isDefaultPrevented/"><code>event.isDefaultPrevented()</code></a> to determine if this method has been called by an event handler that was triggered by this event.</p>

  <example>
    <desc>Cancel the default action (navigation) of the click.</desc>
