title: Pop up window with hidden URL address
body: <p>I am having some difficulties when trying to hide the URL address for pop up window in javascript. Here is my html:</p>
  
  <pre><code>&lt;div id="menu"&gt;
      &lt;ul&gt;
          &lt;li&gt;&lt;a onclick="PopupCenter('./about.html', 'About ePlanner',600,400);" href="javascript:void(0);"&gt;About ePlanner&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a onclick="PopupCenter('./team.html', 'Project Members',600,400);" href="javascript:void(0);"&gt;Project Members&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a onclick="PopupCenter('./faq.html', 'FAQ',600,400);" href="javascript:void(0);"&gt;FAQ&lt;/a&gt;&lt;/li&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And my javascript for pop up window:</p>
  
  <pre><code>&lt;script&gt;
  function PopupCenter(pageURL, title,w,h) {
      var left = (screen.width/2)-(w/2);
      var top = (screen.height/2)-(h/2);
      var targetWin = window.open (pageURL,title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+top+', left='+left);
  } 
  &lt;/script&gt;
  </code></pre>
  
  <p>I was wondering is it possible to hide the URL address and as well as the window frame. </p>
