title: Accessing a published Google Sheets from a webpage
body: <p>I have a page with this code:</p>
  
  <pre><code>xmlhttp = new XMLHttpRequest(); }
  xmlhttp.open("GET","https://spreadsheets.google.com/feeds/cells/14EiO1Fq6Z9eiN03eejNMlPAISTmwwCLhtcZxoSqLszo/ovqq6ni/private/full",false);
  xmlhttp.send();
  </code></pre>
  
  <p>The code is failing due to:
  No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<a href="http://www.acme.com" rel="nofollow">http://www.acme.com</a>' is therefore not allowed access.</p>
  
  <p>How do I solve this? I tried using the callback parameter but that just results in the same error.</p>
  
  <p>Is the problem the way I'm retrieving the URL, or something on the Google Sheets / Spreadsheets end?</p>
