Answer 1

There is probably a better way to do this… But if you output an element with your scriptlet, and then see if that element exists…

<% out.println( "<div id='close'>Can you see this</div>" ); %>

<script type="text/javascript">

     alert( document.getElementById("close").innerHTML );

     if ( document.getElementById("close") )
     {
         window.close();
     }
</script>
