后台使用的是servlet：

public class GetChangeServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
private String nickname=new String();
private String email=new String();
private String school=new String();
private String college=new String();
private String profession=new String();
private String grade=new String();
private String id=new String();

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String openid=(String) request.getParameter("openid");
Map<String, Object> map=UserDao.getSingleUserByOpenID(openid);
System.out.println(map);
nickname=map.get("nickname").toString();
email=map.get("email").toString();
school=map.get("school").toString();
college=map.get("college").toString();
profession=map.get("profession").toString();
grade=map.get("grade").toString();
id=map.get("id").toString();
//      System.out.println("nickname"+nickname+id);
JSONObject json = new JSONObject();
json.put("openid", openid);
json.put("nickname", nickname);
json.put("email", email);
json.put("school", school);
json.put("college", college);
json.put("profession", profession);
json.put("grade", grade);
json.put("id", id);//这里需要分开处理。。。。
response.setContentType("text/html;charset=UTF-8");
response.getWriter().write(json.toString());
//  System.out.println("json.toString()");

//        String username1=(String) request.getParameter("username");
//        String email1=(String) request.getParameter("email");

注意问题：

1、前面的js的引用顺序如果反了会不执行。

2、使用标签显示数据的时候不能换行，不然会出现多余的空格。
