ionic上拉翻页及下拉刷新

测试用的Reddit API:

https://www.reddit.com/dev/api

默认显示20多条记录：
www.reddit.com/r/Android/new/.json

取某个item前面的记录
www.reddit.com/r/Android/new/.json?before=ITEM_NAME_HERE

=>ITEM_NAME_HERE可以看做是reddit中item的标识符(由kind + _ + id组成），可以从返回的json数据中取到，比如t3_3r5w9j

上拉翻页：
http://ionicframework.com/docs/api/directive/ionInfiniteScroll/

只需要在list的后面加上：

<ion-infinite-scroll  on-infinite="loadOlderStories()"  distance="1%"> </ion-infinite-scroll>

并在loadOlderStories处理结束后调用$scope.broadcast('scroll.ifiniteScrollComplete')。

代码二：www/js/app.js

// Ionic Starter App// angular.module is a global place for creating, registering and retrieving Angular modules// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)// the 2nd parameter is an array of 'requires'(function () {  var app = angular.module('myreddit', ['ionic', 'angularMoment']);  app.controller('RedditCtrl', function ($http, $scope) {    $scope.stories = [];    $scope.loadOlderStories = function(){      var params = {};      if($scope.stories.length > 0){        params['after'] = $scope.stories[$scope.stories.length -1].name;      }      $http.get('https://www.reddit.com/r/Android/.json', {params: params})        .success(function (response) {          angular.forEach(response.data.children, function (child) {            $scope.stories.push(child.data);          });          $scope.$broadcast('scroll.infiniteScrollComplete');        });    }  });  app.run(function ($ionicPlatform) {    $ionicPlatform.ready(function () {      // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard      // for form inputs)      if (window.cordova && window.cordova.plugins.Keyboard) {        cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);      }      if (window.StatusBar) {        StatusBar.styleDefault();      }    });  })})();

下拉刷新：
http://ionicframework.com/docs/api/directive/ionRefresher/

只需要在列表页的最前面加上

<ion-refresher    pulling-text="Pull to refresh..."    on-refresh="loadNewerStories()">  </ion-refresher>

并在loadNewerStories处理结束后调用$scope.broadcast('scroll.refreshComplete') 。
