title: avoid opening extra window/tab by checking whether browser tab is already opened
body: <p>Am trying the below case using jquery</p>
  
  <p>Is there any way to check all the windows/tabs opened in the browser (IE) and open a link in same window in order to avoid multiple windows i.e.
  say i have a window which has links</p>
  
  <p>a,b,c where a (link=google/abc) b (link=google/def) c (link=google/xyz)</p>
  
  <p>the code should check only if the link starts with google in above link and open a window/tab in the same tab where the address starts with google</p>
  
  <p>I am trying with the below code</p>
  
  <pre><code>window.open(url, "windowName")
  </code></pre>
  
  <p>but the above approach will only work if i open the window using window.open and keep a reference as windowName. Is there any other way other than this?</p>
