title: is it possible a link from iframe to affect the mother page/main page where iframe is displayed?
body: <p>I have a iframe that is included in another page (mother page). </p>
  
  <pre><code>&lt;iframe name="commentsiframe" id="commentsiframe" onLoad="autoResize('commentsiframe');" width="100%" src="iframe.php" scrolling="no"  marginheight="0" frameborder="0" &gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>What if i have a </p>
  
  <pre><code>&lt;a href="#top"&gt;go top&lt;/a&gt;
  </code></pre>
  
  <p>in the iframe page. And when i click on it i want to manipulate the main page/mother page and make it go on top.</p>
  
  <p>I have no ideea if it is possible, but i assume if yes it must be javascript!</p>
