title: how to get browser window object using java script or jQuery
body: <p>I would like to get window object of the already open window and I don't want to open a new window when expected window is closed.</p>
  
  <p>I tried the following option:</p>
  
  <pre><code>var windowObj = window.open('','windowName', '');
  </code></pre>
  
  <p>However it opens a new window when expected window is not present/closed.</p>
  
  <p>Please suggest me something to get the window object using JavaScript or jQuery.</p>
