angularjs实现页面加载到最底部自动换页功能

在移动端已经不需要点击页码换页了，而是通过手触滑动，滑动到底部自动加载，这个demo是项目中写的一个例子，之总结了js部分，贴出代码分享，此功能依赖于infinite- 

(function() {

    var myApp = angular.module('myApp', ['infinite-scroll']);

    myApp.controller('DemoController', function($scope, Reddit) {
      $scope.reddit = new Reddit();
      console.log("hello");
    });

    // Reddit constructor function to encapsulate HTTP and pagination logic
    myApp.factory('Reddit', function($http) {
      var Reddit = function() {
        this.items = [];
        this.busy = false;
        this.page = 1;
      };

      Reddit.prototype.nextPage = function() {
        if (this.busy) return;
        this.busy = true;

        var url = "" + this.page ;
        $http.get(url).success(function(data) {
          var items = data.items;
         for (var i = 0; i < items.length; i++) {
            this.items.push(items[i]);
          }
         this.page = data.page + 1 ;//第几页
         this.busy = false;
        }.bind(this));

      };

      return Reddit;
    });
})()
