AJAX实现异步刷新

jsp页面：

<a href="javascript:void(0)" onclick="deleteUserById(${user.userId},this)">删除</a>

script代码：

<script type="text/javascript" src="js/jquery-1.8.3.js" ></script><script type="text/javascript">function deleteUserById(userId,obj){$.post("DeleteUserServlet",{id:userId},function(data){if("删除成功"==data){alert(data);$(obj).parent().parent().remove();}else{alert(data);}});}</script>

Servlet代码：

response.setContentType("text/html");response.setCharacterEncoding("UTF-8");PrintWriter out = response.getWriter();int userId = Integer.parseInt(request.getParameter("id"));UserDao userDao = UserDao.getInstance();if(userDao.deleteUserByUserId(userId)){out.print("删除成功");}else{out.print("删除失败");}
