title: How to access an html object on another page
body: <p>my problem is that I want to get access from page <code>index1.html</code> to object in page <code>index2.html</code>, for example:</p>
  
  <p><code>&lt;button id="btnIndex1" onclick="$('#PopUpDIvIdInPageIndex2').show();"&gt;btn in index1.html&lt;/button&gt;</code></p>
  
  <p>Solutions with coockies and another storages are not useful for me because I need immediately(real-time) access.
  Any suggestions?</p>
