javascript windows "Yes/No" asking twice?
<p>I am using below code for javascript window "Yes/No". It is firing twice. Is there any way I can avoid this? Or use any other code?. I need this code behind.</p>

<pre><code>Response.Write("&lt;script language='javascript'&gt; { self.close() }&lt;/script&gt;");
</code></pre>
