如何限制ng-repeat輸出的數(shù)據(jù)條數(shù)？比如我有30條數(shù)據(jù)，我只需要循環(huán)前五條出來就可以了。html如下：                    <div class="video-cover item-inner">                         <img class="icon" src="../images/m_home/icon_play.png">                         <img class="cover" ng-src="{{list.cover}}">                     </div>                     <div class="video-mask"></div>                     <div class="video-bar">                         <span class="video-duration">{{list.duration_format}}</span>                         <p class="video-title">{{list.title}}</p>                     </div>                 </a>$http.jsonp('http://api.ergeng.com/normalvideo/list?callback=JSON_CALLBACK&user_id='+$scope.details.user_id+'').success(function(data){             $scope.lists = data.data.list;         });
