angularjs后台获取json数据传前台，回调函数打印data，打印出的是前端界面，这是怎么回事

Question

后台处理： @RequestMapping("/querySectors")
public ModelAndView querySectors()throws Exception{

    //调用service查找数据库
    List<Sectors> sectorsList = sectorsService.findSectorsByName(null);
    //返回modelandview
    ModelAndView modelAndView = new ModelAndView();
    /*modelAndView.addObject("sectorsList", sectorsLis![图片说明](https://img-ask.csdn.net/upload/201707/24/1500862378_683537.png)t);
    System.out.println(sectorsList);*/
    JSONArray jsay=JSONArray.fromObject(sectorsList);
    System.out.println(jsay);

    modelAndView.setViewName("sectors/sectorsList");
    return modelAndView;
    前台控制器：
      var url = "http://localhost:8080/jjzdoa/querySectors.action";
 $http(
    {  
        method  : 'POST',  
        url     : url,  
        datatype:'json',
        params    :{userid:'',password:''},  // 传递数据作为字符串，从前台传到后台  
     }
    ).success(function (data) {

     confirm(data);

          /*   $scope.msg = data.msg ;
            if(data.msg==true){
                 localStorage.setItem("userId", name);
                window.location = "../kuaishuxd.html";                    
            } else{
                confirm("用户名或密码错误！");
            } */     
        });

}
});

打印的代码在哪呢？？？
考虑 ajax是异步的， 打印的js也要在异步触发之后触发
