Info

Thanks! Thanks for placing your order. We'll ship your goods as soon as possible. I don't need to make any code changes to integrate this view into the application because I already added the required statements when I defined the Checkout action method back in Listing 9-18. Now customers can go through the entire process, from selecting products to checking out. If they provide valid shipping details (and have items in their cart), they will see the summary page when they click the Complete order button, as shown in Figure 9-8. Figure 9-8. The thank-you page Summary I have completed all the major parts of the customer-facing portion of SportsStore. It might not be enough to worry Amazon, but I have a product catalog that can be browsed by category and page, a neat shopping cart, and a simple checkout process. The well-separated architecture means I can easily change the behavior of any piece of the application without worrying about causing problems or inconsistencies elsewhere. For example, I could process orders by storing them in a database, and it would not have any impact on the shopping cart, the product catalog, or any other area of the application. In the next chapter, I use two different techniques to create a mobile version of the SportsStore application. 254
CHAPTER 10 SportsStore: Mobile There is no escaping the popularity of devices such as smartphones and tablets, and if you want to deliver your application to the widest possible audience, you will have to embrace the world of mobile web browsers. If I sound less than enthusiastic, it is because the phrase mobile web browsers runs the gamut from fast, capable, and modern browsers that can rival a decent desktop browser right through to the slow, inconsistent, and outdated. The bottom line is that delivering a good experience to mobile users is hard—much harder than delivering content just to desktops. It takes careful planning, design and an enormous amount of testing—and even then it is easy to be caught out by a new smartphone or tablet. Putting Mobile Web Development in Context The MVC Framework does have some features that can help with mobile development. But the MVC Framework is a server-side framework that receives HTTP requests and generates HTML responses and there is a limited amount it can do to deal with the wide variation in capabilities that you will encounter when targeting mobile clients. The degree to which The MVC Framework can help depends on the mobile strategy that you have adopted. There are three basic mobile web strategies you can follow, which I describe the following sections. Note There is a fourth option, which is to create a native application, but I don’t discuss that here since it doesn’t directly involve the MVC Framework or, for that matter, web applications. Doing Nothing (Or As Little As Possible) It may seem like an odd idea to do nothing, but some mobile devices are capable of handling content that has been developed for desktop clients. Many—admittedly the most recent—have high-resolution, high-density displays with plenty of memory and browsers that can render HTML and run JavaScript quickly. If your app isn’t too demanding, you may find that many mobile devices won’t encounter any problems at all displaying your application content. As an example, Figure 10-1 shows how an iPad displays the SportsStore application without any modifications. 255
