想做一个修改用户信息的模块，通过js预加载了用户的信息，但是怎么将修改后的信息提交给后台controller呢？

	 	document.getElementById("answer").value = answer;

	 	document.getElementById("role").value = role;

controller代码



@RequestMapping("submitupdate")

	public ModelAndView submitUpdate(Model model,HttpServletRequest request, HttpSession session)

	{

		ModelAndView mv = new ModelAndView();

		String tip="";

		

		

		User user1 = (User) session.getAttribute(Const.CURRENT_USER);

		

		String username = (String) request.getAttribute("username");

		System.out.println(username);

		String email = (String) request.getAttribute("email");

		String phone = (String) request.getAttribute("phone");

		String question = (String) request.getAttribute("question");

		String answer = (String) request.getAttribute("answer");

		Integer role =  (Integer) request.getAttribute("role");

		Date createTime = (Date) request.getAttribute("createTime");

		

		Date updateTime = new Date();

		

		

		User user = new User(user1.getId(),username,null,email,phone,question,answer, role,createTime, updateTime);

		

		ServerResponse<User> response = userService.updateSelfInfo(user);

		if(response.isSuccess())

		{

			tip="修改成功";

		}

		else tip="修改失败";

		mv.addObject("tip", tip);

		mv.setViewName("user/updateResult");

		return mv;
