-The phone details view displays one large image of the current phone and several smaller thumbnail
-images. It would be great if we could replace the large image with any of the thumbnails just by
-clicking on the desired thumbnail image. Let's have a look how we can do this with angular.
-
-__`app/partials/phone-detail.html`:__
-<pre>
-<img ng:src="{{mainImageUrl}}" class="phone"/>
-
-<h1>{{phone.name}}</h1>
-
-<p>{{phone.description}}</p>
-
-<ul class="phone-thumbs">
- <li ng:repeat="img in phone.images">
- <img ng:src="{{img}}" ng:click="setImage(img)">
- </li>
-</ul>
-...
-</pre>
-
-__`app/js/controllers.js`:__
-<pre>
-...
-function PhoneDetailCtrl($xhr) {
- var self = this;
-
- $xhr('GET', 'phones/' + self.params.phoneId + '.json', function(code, response) {
- self.phone = response;
- self.mainImageUrl = response.images[0];
- });
-
- self.setImage = function(imageUrl) {
- self.mainImageUrl = imageUrl;
- }
-}
-
-//PhoneDetailCtrl.$inject = ['$xhr'];
-</pre>
-
-__`test/e2e/scenarios.js`:__
-<pre>
-/* jasmine-like end2end tests go here */
-...
- describe('Phone detail view', function() {
-
- beforeEach(function() {
- browser().navigateTo('../../app/index.html#/phones/nexus-s');
- });
-
-
- it('should display nexus-s page', function() {
- expect(binding('phone.name')).toBe('Nexus S');
- });
-
- it('should display the first phone image as the main phone image', function() {
- expect(element('img.phone').attr('src')).toBe('img/phones/nexus-s.0.jpg');
- });
-
-
- it('should swap main image if a thumbnail image is clicked on', function() {
- element('.phone-thumbs li:nth-child(3) img').click();
- expect(element('img.phone').attr('src')).toBe('img/phones/nexus-s.2.jpg');
-
- element('.phone-thumbs li:nth-child(1) img').click();
- expect(element('img.phone').attr('src')).toBe('img/phones/nexus-s.0.jpg');
- });
- });
-});
-</pre>

-## Discussion:
-
-Adding the phone image swapping feature is fairly straightforward:
-
-* We defined the `mainImageUrl` model property in the details controller (`PhoneDetailCtrl`) and
-set the default value of `mainImageUrl` to the first image in the array of images.
-* We created a `setImage` controller method to change `mainImageUrl` to the image clicked on by
-the user.
-* We registered an `{@link angular.directive.ng:click ng:click}` handler for thumb images to use
-the `setImage` controller method.
-* We expanded the end-to-end test to verify that our new feature is swapping images correctly.
