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;
 });
