controller中上拉加载功能使用

app.controller(&#39;wdListCtrl&#39;, [&#39;$scope&#39;,&#39;catInfoService&#39;, function ($scope,catInfoService) {
//下拉加载service
 $scope.catinfo = new catInfoService();

define([&#39;jquery&#39;,&#39;app&#39;], function ($,app) {
 app.service(&#39;catInfoService&#39;, [&#39;$location&#39;,&#39;$http&#39;, function($location,$http) {
  var CatInfo = function () {
   this.items =null;
   this.busy = false;
   this.after = &#39;&#39;;
   this.page = 1;
   this.pagenum =10;
   this.title = &#39;&#39;;
   this.varieties =&#39;&#39;;
  };
  CatInfo.prototype.nextPage = function () {
   if (this.busy) return;
   this.busy = true;
   var url = baseurl+"接口地址?page=" + this.page + "&pagenum="+ this.pagenum + "&title="+this.title+ "&varieties="+this.varieties+"&callback=JSON_CALLBACK";
   $http.jsonp(url).success(function(data) {
    var items =data.data;
    console.log(items);
    if( this.items == null){
     this.items=items;
    }else{
     for (var i =0;i < items.length; i++) {
      this.items.push(items[i]);
     }
    }
    this.after = "t_" + this.items[this.items.length -1 ].id;
    if(items != null){
     if(items.length< 10){
      this.busy = true;
     }else{
      this.busy = false;
     }
    }
    this.page +=1;
   }.bind(this));
