Pull to Refresh

Refreshing a List

Adding pull-to-refresh functionality to a list is easy in Ionic. To start, we create a basic Ionic list, but with one change. By prepending the ion-refresher directive outside of the list, we add everything we need:

<body ng-app="ionicApp">
  <ion-header-bar class="bar-energized">
    <h1 class="title">Pull to Refresh!</h1>
  <ion-content ng-controller="TodosCtrl">
    <ion-refresher pulling-text="Pull to refresh" on-refresh="doRefresh()">
      <ion-item ng-repeat="todo in todos">{{todo.name}}</ion-item>


The ion-refresher directive takes several attributes, but the most important is the on-refresh handler. This will call the associated function on your controller. To setup the controller, we create a basic Ionic application:

var app = angular.module('ionicApp', ['ionic'])

app.controller('TodosCtrl', function($scope) {
  $scope.todos =  [
    {name: "Do the dishes"},
    {name: "Take out the trash"}
  $scope.doRefresh = function() {
    $scope.todos.unshift({name: 'Incoming todo ' + Date.now()})

Because we are making simple scope changes outside of the context of a digest cycle, we have to use $scope.$apply(). Typically, data will come from an external source, like ng-resource, Restangular, or the $http directive. In this case, we can use a promise and manually running a digest cycle is not necessary:

.success(function(data) {
  $scope.resource = data.resource
.finally(function() {

The important thing to remember here is that the scroll.refreshComplete event must be called to resume normal use of the list.
