title: new popup window on every click
body: <p>I've a pop up window which i'm opening using below script. On every click, i want to open new pop up. 
  I understand, having unique name for the window will solve the problem (In this case "SampleWindow"). 
  What's the best way to maintain the uniqueness of the window ? Is there any other way to manage javascript popup ?</p>
  
  <pre><code>window.open(url, 'SampleWindow', 'WIDTH=300,HEIGHT=250');
  </code></pre>
