};3.html文件引用的updateUser.css文件
body { font-size: 62.5%; }
label, input { display:block; }
input.text { margin-bottom:12px; width:95%; padding: .4em; }
fieldset { padding:0; border:0; margin-top:25px; }
h1 { font-size: 1.2em; margin: .6em 0; }
div#users-contain { width: 350px; margin: 20px 0; }
div#users-contain table { margin: 1em 0; border-collapse: collapse; width: 100%; }
div#users-contain table td, div#users-contain table th { border: 1px solid #eee; padding: .6em 10px; text-align: left; }
.ui-dialog .ui-state-error { padding: .3em; }
.validateTips { border: 1px solid transparent; padding: 0.3em; }4.后端controller层对应的ajax请求方法
@Controller
public class UserController {
@Resource
private IUserService userService;
@RequestMapping("/updateUser")
@ResponseBody
public boolean updateUser(User user,HttpServletRequest request){
return userService.updateUser(user,request);
}
}5.实现的效果图
6.点击修改按钮，出现对话框
