<script type="text/javascript"> 
function addCookie() 
{ 
if (document.all) 
{ 
window.external.addFavorite('http://www.maopiaopiao.com','毛票票'); 
} 
else if (window.sidebar) 
{ 
window.sidebar.addPanel('毛票票', 'http://www.maopiaopiao.com', ""); 
}

if (document.all) 
{ 
document.body.style.behavior='url(#default#homepage)'; 
document.body.setHomePage('http://www.maopiaopiao.com'); 

} 
else if (window.sidebar) 
{ 
if(window.netscape) 
{ 
try 
{ 
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); 
} 
catch (e) 
{ 

} 
} 
var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components. interfaces.nsIPrefBranch); 
prefs.setCharPref('browser.startup.homepage','http://www.maopiaopiao.com'); 
} 
} 
</script> 

<form>
