我已经遵循了几个教程,试图实现无限滚动在离子上的一种方式,它不调用httprequest,而只是显示更多的元素在DOM中的列表,已经加载(我的JSON返回100+的项目,这是足够的,为我的情况)。
- AngularJS -一个简单的无限滚动(AngularJS方法,不是ionic)
- http://ionicframework.com/docs/api/directive/ionInfiniteScroll/(Ionic manual但是从http加载)
- http://sunnycyk.com/2014/02/ionic-framework-infinite-scrolling/(其他Ionic示例)
下面是我的代码
- I默认显示10项正确与
$scope.numberOfItemsToDisplay = 10;
。 - 不显示
$scope.loadMore;
call所假定的+10项。 - 似乎没有调用
$scope.loadMore = function(...
函数来加载+10更多的滚动到结束。
controller.js
angular.module('starter.controllers', [])
.controller('AppCtrl', function($scope, $ionicModal, $timeout) {
// Form data for the login modal
$scope.loginData = {};
// Create the login modal that we will use later
$ionicModal.fromTemplateUrl('templates/login.html', {
scope: $scope
}).then(function(modal) {
$scope.modal = modal;
});
// Triggered in the login modal to close it
$scope.closeLogin = function() {
$scope.modal.hide();
},
// Open the login modal
$scope.login = function() {
$scope.modal.show();
};
// Perform the login action when the user submits the login form
$scope.doLogin = function() {
console.log('Doing login', $scope.loginData);
// Simulate a login delay. Remove this and replace with your login
// code if using a login system
$timeout(function() {
$scope.closeLogin();
}, 1000);
};
})
.controller('AdsCtrl', function($scope, $http) {
$scope.name = 'World';
$scope.numberOfItemsToDisplay = 10;
$scope.ads = [];
$http.get('http://some-url.com/list.json').success(function(data) {
$scope.ads = data;
});
var counter = 0;
$scope.loadMore = function(done) {
console.log('Loading more', $scope.limit);
if ($scope.ads.length > $scope.numberOfItemsToDisplay)
$scope.numberOfItemsToDisplay += 10; // load 20 more items
done(); // need to call this when finish loading more data
}
$scope.loadMore;
})
.controller('AdCtrl', function($scope, $stateParams) {
})
ads.html
<ion-view title="Ads">
<ion-nav-buttons side="left">
<button menu-toggle="left" class="button button-icon icon ion-navicon"></button>
</ion-nav-buttons>
<ion-nav-buttons side="right">
<button menu-toggle="right" class="button button-icon icon ion-person"></button>
</ion-nav-buttons>
<ion-content has-header="true" on-infinite-scroll="loadMore">
<label class="item item-input">
<i class="icon ion-search placeholder-icon"></i>
<input ng-model="query" type="search" placeholder="Filter" filter="" class="" min-length="" model="" source="">
</label>
<ion-list>
<ion-item ng-repeat="ad in ads | filter:query | limitTo:numberOfItemsToDisplay" class="item item-thumbnail-left" href="#/app/ads/{{ad.id}}">
<img src="http://some-url.com/pictures/{{ad.photo}}">
<h2>{{ad.title}}</h2>
<h4>{{ad.price}} {{ad.currency}}</h4>
<h4>{{ad.group}} » {{ad.category}}</h4>
<h4 style="margin-bottom: 0;">{{ad.shortrelativetime}}</h4>
</ion-item>
</ion-list>
</ion-content>
</ion-view>
任何想法?
我通过使用下面的代码解决了同样的问题,我有时间表[]数组与数据:
HTML:<li class="item" ng-repeat="schedule in Schedules | filter:scheduleSearch | limitTo:numberOfItemsToDisplay">
Display some data
</li>
<ion-infinite-scroll on-infinite="addMoreItem()" ng-if="Schedules.length > numberOfItemsToDisplay"></ion-infinite-scroll>
控制器:
$scope.numberOfItemsToDisplay = 10; // Use it with limit to in ng-repeat
$scope.addMoreItem = function(done) {
if ($scope.Schedules.length > $scope.numberOfItemsToDisplay)
$scope.numberOfItemsToDisplay += 10; // load number of more items
$scope.$broadcast('scroll.infiniteScrollComplete')
}
这里,我每次调用addMoreItem()时加载10个项目。
对不起,我没有读你所有的代码,但我基本上知道你的问题。
我建议你使用ion-infinite-scroll
,也许它会有帮助。
参见http://codepen.io/elm/pen/Becqp了解更多关于实现的信息。
希望能帮到你^^
我添加numberOfItemsToDisplay ">
</ion-infinite-scroll>
