form知识点一:
一般form表单提交onsubmit提交都会有个地址,但是如果没有地址的话会按照当前的页面地址提交:
前端:
fcheck是检查有没有空的标题,
<form method="post" onsubmit="if (!fcheck()) return false;"></form>
后台:
@RequestMapping(value = "/homepage/circle/detail", method = RequestMethod.POST) public ModelAndView saveCircle( @ModelAttribute("circle") Circle circle, HttpServletRequest request) { User user = (User) request.getSession().getAttribute("SESSION_USER"); if (user == null || !user.hasMakeCoursePermission()) { throw new PermissionException("用户没有管理圈子的权限"); } circleDAO.saveCircle(circle); return new ModelAndView(new RedirectView("list.html")); }
