IN THIS CHAPTER
Want to avoid the whole business of writing Ajax code yourself? If so, you're in luck because there are literally dozens of Ajax frameworks out there that will do the work for you. An Ajax framework contains the code you need to support Ajax, and that code has already been written for you. All you have to do to use an Ajax framework is download it and put it to work (most are free). Want to save time using Ajax? Use an Ajax framework.
Because these Ajax frameworks are free, and are often developed by hobbyists, they're sometimes not developed with the best programming practices in mind. For that reason, this discussion starts with a special Ajax framework, the Ajax Utility Library, developed for this book, and which uses good programming practices. The Ajax Utility Library is easy to use and simple to install.
