title: Reloading parent window with a button in the iframe
body: <p>I have an iframe in a page like</p>
  
  <pre><code>&lt;iframe src="something.html"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>and in the <em>something.html</em> page, I have a form and a button.</p>
  
  <pre><code>&lt;form action="anywhere.html"&gt;
  &lt;input type="button" name="submit" value="submit"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>When I click on the submit button, it only reloads the page <em>anywhere.html</em>  (inside the iframe). But I want <em>anywhere.html</em> to load in the same main window (not in a new tab or window or not in the iframe). How can this be done?</p>
