Question

我有两个离子滚动标签。这些离子滚动标签中的每一个都是一个列表。这些列表中的每一个都以10个项目开头，当用户到达特定离子滚动的底部时，它应该加载更多。我面临的问题是这种方法无法正常工作。如果我滚动浏览第一个滚动窗口并对所有项目进行分页，则应该说不再有内容。但这不会发生，相反，如果我滚动浏览第二个滚动窗口，那么它将在第一个和第二个离子滚动窗口（我不想要）中加载更多项目。基本上我希望两个离子卷轴完全相互独立。我希望每个人都加载它自己的内容。我希望这是有道理的。这是我的代码：

        <ion-scroll style="height:50%">
            <ion-list>
                <ion-item collection-repeat="list2 in _list2">

                    <h2>Item</h2>

            <button class="button button-full button-outline button-positive" ng-if="noMoreContent2">

使用Javascript：

angular.module('ionicApp', ['ionic'])

  .controller('MyCtrl', function($scope) {






  $scope._list = [];

  $scope.populateList = function() {
    for (var i = 0; i <= 9; i++) {


      $scope._list.push({});
    }
    console.log($scope._list.length);
    $scope.$broadcast('scroll.infiniteScrollComplete');
  }

  $scope.noMoreContent = false;

  $scope.canWeLoadMoreContent = function() {
    if($scope._list.length > 15) {
      $scope.noMoreContent = true;

      return false;
    }else{
      return true;
    }
  }
  $scope.populateList();





  $scope._list2 = [];

  $scope.populateList2 = function() {
    for (var i = 0; i <= 9; i++) {



      $scope._list2.push({});

    }
    console.log($scope._list2.length);
    $scope.$broadcast('scroll.infiniteScrollComplete');
  }

  $scope.noMoreContent2 = false;

  $scope.canWeLoadMoreContent2 = function() {
    if($scope._list2.length > 15) {
      $scope.noMoreContent2 = true;

      return false;
    }else{
      return true;
    }
  }



  $scope.populateList2();




});

问题来自于＆＃39;要求＆＃39; ？^ ionicScroll在指令中未正确解析。不知道为什么，因为我不是AngularJS专家。也就是说，我发现了一种解决方法，即在内容标记周围添加额外的div，如http://codepen.io/priand/pen/PzYbZG中所示，如果这有助于某人。

<div>
<ion-content class="has-header col col-50">
  <ion-list>
    <ion-item ng-repeat="item in items" 
              item="item">
      Item {{ item.id }}
    </ion-item>
  </ion-list>
  <ion-infinite-scroll ng-if="!noMoreItemsAvailable" on-infinite="loadMore()" distance="10%"></ion-infinite-scroll>
</ion-content>
</div>

<div>
<ion-content class="has-header col col-offset-50 col-50">
  <ion-list>
    <ion-item ng-repeat="item in items2" 
              item="item">
      Item {{ item.id }}
    </ion-item>
  </ion-list>
  <ion-infinite-scroll ng-if="!noMoreItemsAvailable2" on-infinite="loadMore2()" distance="10%"></ion-infinite-scroll>      
</ion-content>
</div>

多次离子滚动，无限滚动
