这是我的确认框代码.当我按下OK它应该调用删除功能.当我按下Cancel它应该返回主页,但即使我选择,文件也会被删除Cancel.这是我的代码.怎么了 ？

var response = confirm ("Are you sure you want to permanently delete this user?");  

if (response)  
{  
  <% String userName =request.getParameter("userName");      
     del.del(userName);
   %> 
  window.location.href='adminHome.jsp';
}
else
{
  window.location.href='adminHome.jsp'; 
}
