Javascript to identify if a window is open
<p>I want to identify if a window is open prior to opening the page. </p>

<p>i.e. </p>

<pre><code>winObj = window.open("Test.aspx",WinName",...); 
</code></pre>

<p>I have to find whether the Test.aspx page is open already before opening the same. </p>

<p>Please help!! </p>
