title: jquery window.parent
body: <p>I can use this just fine in a window</p>
  
  <pre><code>$('#dropDownSpan').css('visibility', 'visible'); 
  </code></pre>
  
  <p>but how can I use it in another window which is child of this window or may be opened by this window.</p>
  
  <p>I tried:</p>
  
  <pre><code> $window.parent.('#dropDownSpan').css('visibility', 'visible'); 
  </code></pre>
  
  <p>but that didnt work, any idea?</p>
