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:

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();
});
该问题来自指令中未正确解决的“require”?^ionicScroll。不知道为什么，因为我不是 AngularJS 专家。也就是说，我找到了一种解决方法，即在内容标签周围插入一个额外的 div，如http://codepen.io/priand/pen/PzYbZG中所示，如果这对某人有帮助的话。
<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>
