Hai kennedy,

This may help you

function Delete_Cookie( name, path, domain ) 
{
   if ( Get_Cookie( name ) )
   document.cookie=name+"="+((path) ? ";path="+path:"")+((domain)?";domain="+domain:"") +
                                   ";expires=Thu, 01-Jan-1970 00:00:01 GMT";
}

or

function del_cookie(name)
{
    document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
}
