54 Part I: Introduction Part I: Introduction 55 Reliability Ajax applications should provide accurate information and preserve the integrity of data. Privacy While user-generated data can and should be used to improve the user experience, users' privacy should also be respected, and users should be aware of when and how their data is used. Accessibility Ajax applications should work for users with particular disabilities and of different ages and cultural backgrounds. Compatibility As an extension to accessibility, Ajax applications should work on a wide range of browser applications, hardware devices, and operating systems.

Frankly, there's more work required to make it production-ready, but it's pretty neat that our basic Ajax code could be modified so easily to do it. Complete the Live Search by scrapping the Find Anagrams! button, which is now obsolete. 2. Progress Indicator The input field is limited to five characters because long queries take a very long time. But even with five characters, the delay will be noticeable, especially in a real-world context, so we'll ease the pain with a Progress Indicator (Chapter 14).

Desirable Attributes of Ajax Applications Ajax is about improving user experience and delivering value to the organizations that own and use web applications. Here, we'll look at the key attributes of an ideal Ajax application. Reality dictates that you'll never get the best of all worlds, so you'll have to make trade-offs based on how important you consider each attribute. The Ajax Patterns are intended to help you deal with these trade-offs. Usability Ajax applications should be as intuitive, productive, and fun to use as possible.
