基于AngularJS实现页面滚动到底自动加载数据的功能

 <div ng-controller='PostListController'>   <div infinite-scroll='demo.nextPage()' infinite-scroll-disabled='demo.busy' infinite-scroll-distance=''>     <div ng-repeat='item in demo.items'>       <p>         <input type="hidden" value="{{item.PostId}}" />         <label>{{item.WriterName}}</label>         <label>{{item.WriterMail}}</label>         <label>{{item.WreckerName}}</label>         <label>{{item.StartDate}}</label>         <label>{{item.Location}}</label>         <label>{{item.Story}}</label>       </p>     </div>     <div ng-show='demo.busy'>Loading data...</div>   </div> </div>

 var ftitAppModule = angular.module('ftitApp', ['infinite-scroll']); ftitAppModule.controller('PostListController',    function ($scope, Demo) {     $scope.demo = new Demo(); }); // 创建后台数据交互工厂 ftitAppModule.factory('Demo', function ($http) {   var Demo = function () {     this.items = [];     this.busy = false;     this.after = '';     this.page = ;   };   Demo.prototype.nextPage = function () {     if (this.busy) return;     this.busy = true;     var url = "http://...:/api/post/nextpage?id=" + this.page + "&callback=JSON_CALLBACK";     $http.jsonp(url).success(function (data) {       var items = data;       for (var i = ; i < items.length; i++) {         this.items.push(items[i]);       }       this.after = "t_" + this.items[this.items.length - ].id;       this.busy = false;       this.page += ;     }.bind(this));   };   return Demo; });
