Figure 3.8 MVC as it is commonly applied in the web application. The web page/servlet acts as the Controller and first queries the Model to get the relevant data. It then passes this data to the template file (the View), which generates the content to be forwarded to the user. Note that this is a read-only situation. If we were modifying the Model, the flow of events would differ slightly, but the roles would remain the same.

basically the same, and this is how MVC is generally understood in the web application world. Describing our web architecture using MVC is a useful approach, and it will continue to serve us well as we move from classic to Ajax-style applications. But it isn t the only use to which we can put MVC in Ajax. In chapter 4, we will examine a variation on the pattern that allows us to reap the advantages of structured design throughout our application. Before we do that, though, let s look at another way of introducing order to our Ajax applications. As well as refactoring our own code, we can often rationalize a body of code by making use of third-party frameworks and libraries. With the growing interest in Ajax, a number of useful frameworks are emerging, and we conclude this chapter with a brief review of some of the more popular ones.

A goal of most refactoring is reducing the amount of repetition in the codebase, by factoring details out to a common function or object. If we take this to its logical conclusion, we can wrap up common functionality into libraries, or frameworks, that can be reused across projects. This reduces the amount of custom coding needed for a project and increases productivity. Further, because the library code has already been tested in previous projects, the quality can be expected to be high. We ll develop a few small JavaScript frameworks in this book that you can reuse in your own projects. There s the ObjectBrowser in chapters 4 and 5, the CommandQueue in chapter 5, the notifications frameworks in chapter 6, the StopWatch profiling tools in chapter 8, and the debugging console in appendix A. We ll also be refactoring the teaching examples in chapters 9 through 13 at the end of each chapter, to provide reusable components. Of course, we aren t the only people playing this game, and plenty of JavaScript and Ajax frameworks are available on the Internet, too. The more established of these have the advantage of some very thorough testing by a large pool of developers. In this section, we ll look at some of the third-party libraries and frameworks available to the Ajax community. There s a lot of activity in the Ajax framework space at the moment, so we can t cover all the contenders in detail, but we ll try to provide you with a taste of what sort of frameworks exist and how you can introduce order into your own projects by using them.

Introducing order to Ajax
3.5.1 Cross-browser libraries
As we noted in section 3.2.1, cross-browser inconsistencies are never far away when writing Ajax applications. A number of libraries fulfill the very useful function of papering over cross-browser inconsistencies by providing a common fa ade against which the developer can code. Some focus on specific pieces of functionality, and others attempt to provide a more comprehensive programming environment. We list below the libraries of this type that we have found to be helpful when writing Ajax code. x library The x library is a mature, general-purpose library for writing DHTML applications. First released in 2001, it superseded the author s previous CBE (CrossBrowser Extensions) library, using a much simpler programming style. It provides cross-browser functions for manipulating and styling DOM elements, working with the browser event model, and includes out-of-the-box support libraries for animation and drag and drop. It supports Internet Explorer version 4 upward, as well as recent versions of Opera and the Mozilla browsers. x uses a simple function-based coding style, taking advantage of JavaScript s variable argument lists and loose typing. For example, it wraps the common document.getElementById() method, which accepts only strings as input, with a function that accepts either strings or DOM elements, resolving the element ID if a string is passed in but returning a DOM element unmodified if that is passed in as argument. Hence, xGetElementById() can be called to ensure that an argument has been resolved from ID to DOM node, without having to test whether it s already been resolved. Being able to substitute a DOM element for its text ID is particularly useful when creating dynamically generated code, such as when passing a string to the setTimeout() method or to a callback handler. A similarly concise style is used in the methods for manipulating DOM element styling, with the same function acting as both getter and setter. For example, the statement
will return the width of the DOM element myElement, where myElement is either a DOM element or the ID of a DOM element. By adding an extra argument, like so
we set the width of the element. Hence, to set the width of one element equal to another, we can write
