Figure 27-3. Monitoring the connections made by the browser The second difference is that the data is processed by the browser, rather than at the server, as the view is rendered. To test this, you can edit the getAllItems function so that it doesn’t make the Ajax request or process the data it receives, like this: ... function getAllItems() { return; sendAjaxRequest("GET", function(data) { model.reservations.removeAll(); for (var i = 0; i < data.length; i++) { model.reservations.push(data[i]); } }); } ... The function will return before the Ajax request is made and you can see the effect by restarting the application, as shown in Figure 27-4. This may seem obvious, but it is an important characteristic of SPAs that the browser does a lot more work, including processing data and generating HTML content. 722
Figure 27-4. Demonstrating that the data is retrieved and processed by the browser The final difference is that the data bindings are live, meaning that changes in the data model are reflected in the content that the foreach and text bindings generate. To test this, ensure that you return the getAllItems function to its working state and reload the application. Once the browser has requested, received and processed the data, open the F12 tools and switch to the Console section. Enter the following command into the console and hit Enter: model.reservations.pop() This expression removes the last item from the array of data objects in the model and as soon as you enter the command, the layout of the HTML page will reflect the change, as shown in Figure 27-5. The overall effect is that I have shifted some of the complexity of generating the HTML from the server to the client. Figure 27-5. Manipulating the model via the JavaScript console Improving the Delete Feature Now that you have seen how applying Knockout has changed the nature of the client, I am going to quickly loop back and remove a shortcut that I took when I defined the Ajax methods for the application. The removeItem function is badly written: 723
