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 at how we can do this with angular. + +The most important changes are listed below. You can see the full diff on {@link +https://github.com/angular/angular-phonecat/compare/step-9...step-10 +GitHub}: + + +## Controller + +__`app/js/controllers.js`:__ +

+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'];
+
+ +In the `PhoneDetailCtrl` controller, we created the `mainImageUrl` model property and set its +default value to the first phone image url. + +We also created a `setImage` controller method to change the value of `mainImageUrl`. + + +## Template + +__`app/partials/phone-detail.html`:__ +
+
+
+...
+
+
+...
+
+ +We bound the `ng:src` attribute of the large image to the `mainImageUrl` property. + +We also registered an {@link api/angular.directive.ng:click `ng:click`} handler with thumbnail +images. When a user clicks on one of the thumbnail images, the handler will use the `setImage` +controller method to change the value of the `mainImageUrl` property to the url of the thumbnail +image. + + + +## Test + +To verify this new feature, we added two end-to-end tests. One verifies that the main image is set +to the first phone image by default. The second test clicks on several thumbnail images and +verifies that the main image changed appropriately. + +__`test/e2e/scenarios.js`:__ +

+ +You can now refresh the browser tab with the end-to-end test runner to see the tests run, or you +can see them running on {@link +http://angular.github.com/angular-phonecat/step-8/test/e2e/runner.html +angular's server}. + +# Experiments + +* Let's add a new controller method to `PhoneCatCtrl`: + + this.hello = function(name) { + alert('Hello ' + (name || 'world') + '!'); + } + + and add: + + + + to the `index.html` template. + + The controller methods are inherited between controllers/scopes, so you can use the same snippet +in the `phone-list.html` template as well. + +* Move the `hello` method from `PhoneCatCtrl` to `PhoneListCtrl` and you'll see that the button +declared in `index.html` will stop working, while the one declared in the `phone-list.html` +template remains operational. + + +# Summary + +With the phone image swapper in place, we're ready for {@link step_11 step 11} (the last step!) to +learn an even better way to fetch data. + + + -- cgit v1.2.3
