mongoDB 多重数组查询(AngularJS绑定显示 nodejs)

核心代码：

js代码

var lesson = schema({ 
  lessonname: string, 
  intr: string, 
  cretime: date, 
  sort: string, //分类 
  imgurl: string, //封面地址 
  price: number, 
  teacher: string,//教师 
  subtitle:[{ 
    lno: number, 
    sublname: string, 
    src: string, 
    filtered: {type: boolean, default: false} 
    }] 
}); 

我的html代码

<ul class="menu fl"> 
  <li ng-repeat="title in lessoninfo.subtitle" ng-hide="{{!title.filtered}}"><a ng-href="showvideo?lessonname={{lessoninfo.lessonname}}&lessonno={{title.lno}}&lesid={{lesid}}&sublname={{title.sublname}}" rel="external nofollow" >课时{{title.lno}}:{{title.sublname}}</a> </li> 
</ul>

lessoninfo为angularjs接收到后台传过来的数据数组
