title: window.open() works in html file, but not in php file
body: <p><strong>Never mind, guys.  Thanks for your input.  I had another bit of JS grabbing id="btn" because I reused this code from another part of the project.  This is good and working code.</strong></p>
  
  <p>I have this code in the head:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  function windowOpen(url) {
    window.open(url, 'newwindow', 'width=350, height=450, top=200, left=500'); return false;
  }; &lt;/script&gt;
  </code></pre>
  
  <p>and this code down somewhere in the body:</p>
  
  <pre><code>&lt;?php
      echo "&lt;a href=\"#\" onclick=\"windowOpen('http://www.abcdef.com')\" title=\"Pop-out\"&gt;&lt;i class=\"glyphicon glyphicon-new-window\"&gt;&lt;/i&gt;&lt;/a&gt;" 
  ?&gt;   
  </code></pre>
  
  <p>I've tried it with and without php syntax on both html and php files.  The html file always works and the php never does.<br>Any ideas?  Thanks, I appreciate your help.</p>
