<a href="javascript:window.opener=null;'','_self');window.close();"> Shut down </a> 

2. Close the current page (with prompt under IE)
<a href="javascript:window.opener=null;window.close();"> Shut down </a> 

3. Custom prompt closed
<script language="javascript"> 
function custom_close() { 
if (confirm(" Are you sure you want to close this page? ")) { 
window.opener = null;'', '_self'); 
} else {} 
<input id="btnClose" type="button" value=" Close this page " onClick="custom_close()"

<body onbeforeunload="return ' Do you really want to close this window ?'">
