title: how to prevent reopening new window using jQuery?
body: <p>I've recently posted a new question in <a href="https://stackoverflow.com/questions/9358354/jquery-prevent-reopen-a-new-window/9358462">How jQuery can prevent reopening a new window?</a>. At that post, I mentioned to my need for something on <strong>F2</strong> key.<br>
  Now I want to ask another question similar to the question above; This time for clicking on a link.<br>
  I have a link that opens a new window using <code>window.open</code>. I want to prevent user to reopening new window when he clicks on the list if the previous window is still opened.  </p>
  
  <p>What is your suggestion?</p>
