title: window.open create reference to the name based
body: <p>This way I get the reference to the open window:</p>
  
  <pre><code>var refWin = window.open("mypage1", "name_mypage");
  </code></pre>
  
  <p>if you want to close the window, I close with:</p>
  
  <pre><code>refWin.close();
  </code></pre>
  
  <p>if I do a screen refresh (F5) and run the same line, it opens in the same window, because I put the same name.</p>
  
  <pre><code>var refWin = window.open("mypage2", "name_mypage");
  </code></pre>
  
  <p>but with different reference (refWin).</p>
  
  <p>Question: how I can make reference to the window based on the name?, I need to close the window before opening, with the same name.</p>
  
  <p>do something like:</p>
  
  <pre><code>var refWin = window.open("about:blank", "name_mypage");
  refWin.close();
  refWin = window.open("mypage2", "name_mypage");
  </code></pre>
  
  <p>but without having to be a blank window for reference.</p>
  
  <p>thanks</p>
