title: how to jump to another page in Google Apps Script site
body: <p>I would like to give a page transition.</p>
  <p>In web server (Google side), I prepare an html file like this,</p>
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;base target=&quot;_top&quot;&gt;
  &lt;h1&gt;Moving&lt;/h1&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;a href=&quot;https://google.com&quot;&gt;link&lt;/a&gt;
  &lt;script&gt; window.location.href='https://google.com'&lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  <p>Note that using the link <code>link</code>, I can jump to the google page (<code>google.com</code>).</p>
  <p>However I got a console message like below and cannot jump automatically with Javascript...</p>
  <pre><code>Refused to display 'https://google.com/' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.
  </code></pre>
  <p>I think this is a limitation in Google Apps Script..
  Is there anyway to let users jump without clicking the link?</p>
