Demo

!!! this will only work on a simulator or an actual device due to use of touch events !!!

Installation

1. Use bower to install the new module:

bower install ion-alpha-scroll --save

2. Import the ion-alpha-scroll javascript and css file into your HTML file:

<script src="bower_components/ion-alpha-scroll/dist/ion-alpha-scroll.js"></script>
<link href="bower_components/ion-alpha-scroll/dist/ion-alpha-scroll.css" rel="stylesheet">

3. Add ion-alpha-scroll as a dependency on your Ionic app:

angular.module('myApp', [
  'ionic',
  'ion-alpha-scroll'
]);

Usage

To use the ion-alpha-scroll directive simply add the following snippet to your template:

<ion-alpha-scroll ng-model="model" key="keyName" subheader="true">
  Content Goes here...
</ion-alpha-scroll>

where 'ng-model' is the model you would like to sort and 'key' is the name of the key you would like to sort by.

The 'subheader' attribute is optional, to be set if using a subheader in the view to allow proper scroll height.

To display the properties of each item in the model, you can use the 'item' object within the directive:

	<ion-alpha-scroll ng-model="model" key="keyName">
	  <div>Name: {{item.name}}</div>
	  <div>Address: {{item.address}}</div>
	</ion-alpha-scroll>

Heres a quick example:

services.js

angular.module('example.services', [])

.factory('Contacts', function() {

  // Some fake testing data
  var contacts = [
  {
    id: 0,
    name: 'Ben Sparrow',
    address: '123 Fake St.'
    face: 'https://pbs.twimg.com/profile_images/514549811765211136/9SgAuHeY.png'
  }, {
    id: 1,
    name: 'Max Lynx',
    address: '123 Fake St.'

  }

  ...

  ];


  return {
    all: function() {
      return contacts;
    },
    remove: function(contact) {
      contacts.splice(contacts.indexOf(contact), 1);
    },
    get: function(contactId) {
      for (var i = 0; i < contacts.length; i++) {
        if (contacts[i].id === parseInt(contactId)) {
          return contacts[i];
        }
      }
      return null;
    }
  };
});

controllers.js

angular.module('example.controllers', [])

.controller('contactsCtrl', ['$scope','Contacts',function($scope, Contacts) {
 
	$scope.contacts = Contacts.all();
