javascript - How to check if all documents are loaded with Firebase.util pagination -


how can check if have stop calling loadmore() function, because documents have been loaded database?

in example below i'm using ionic, it's same ng-infinite-scroll in angularjs apps.

this actual code:

html:

  ...    <ion-infinite-scroll     ng-if="!nomoreitemstoload"     on-infinite="loadmore()"     distance="5%">   </ion-infinite-scroll>  </ion-content>

js controller:

$scope.loadmore = function(){    console.log('loading more docs...');    items.loadmore();  // calling .next() method inside items service    if( !items.hasnext()) { $scope.nomoreitemstoload = true; }    $scope.$broadcast('scroll.infinitescrollcomplete');  }

js items factory:

.factory('items', function (firebase_url, $firebasearray,  $firebaseobject) {    var itemsref = new firebase(firebase_url + 'items/');   var scrollref = new firebase.util.scroll(itemsref, 'name');    var self = {      getallitems : function(){ ... },       loadmore: function(){        scrollref.scroll.next(4);      },       hasnext: function(){        if(scrollref.scroll.hasnext()) { return true; }        else { return false; }      }   }    return self;  }

do scroll.next in timeout, example:

 loadmore: function(){    $timeout(function() {      scrollref.scroll.next(4);    });  },
