Show popup when the browser closes
<p>popup when the browser closes</p>

<p>I am using onbeforeunload event</p>

<pre><code>&lt;script&gt;
function showPopup()
{

  urlstring = "http://www.mydomain.com/popup.php";
            window.open(urlstring,'mywin',"height=400px,width=500px,status=no,toolbar=no");

}



&lt;/script&gt; 

&lt;body onbeforeunload="showPopup(); "&gt;
</code></pre>

<p>but it also show popup when ever I hit back space and page refresh.</p>

<p><strong>I want show popup only when browser close and not show when  hit back space.</strong></p>

<p>but it shows all conditions.</p>

<p>Please suggest me any other solution for this.</p>
