Ajax in Action excerpt: Using the Model to Generate the View

By Dave Crane, Eric Pascarello and Darren James

01 Dec 2005 | TheServerSide.com

This is the third in a three-part series of excerpts of Manning's Ajax in Action Chapter 4. This is the first of three chapters that apply refactoring and patterns to the client-side codebase. You won't see much of the asynchronous requests that give Ajax its name in this chapter, but the style of programming being discussing here is a direct consequence of being able to make asynchronous requests.

Dividing the codebase into three discrete layers using MVC makes the JavaScript code in an Ajax application more ordered and maintainable, but it also results in a certain amount of overhead of communication between the tiers. In this installation, we look at a way of reducing this overhead by generating the View layer automatically from the Model.
