| ADDING AJAX MAKING EXISTING SITES MORE INTERACTIVE |
Did you know that you can add ajax to an existing web application without redoing the whole thing? this book demonstrates many advantages of adding ajax to enhance, rather than replace, the way your application works. perhaps you have a traditional web application based on submitting a form to update a table. you can enhance it by allowing users to update the table with changes to the form fields, without actually having to submit the form. that’s just one example.
adding ajax is for those of you who are more interested in extending existing applications than in creating rich internet applications. you already know the business-side of applications—web forms, server-side driven pages, and static content—and now you want to make your web pages livelier, more fun, and much more interactive. this book explains:
* a complete overview of ajax technologies
* ways to develop a strategy for changing your site before you code
* how to work with the xmlhttprequest object
* several important ajax libraries, including prototype, script.aculo.us, rico, and mochikit
* the ajax interactive element—how to use events and event handlers that work across browsers
* the concept of web page as space, including three popular approaches to managing web space
* how to make data updates, including adding new data, and deleting and making updates, all from within a single page
* the effects ajax has on the web—breaking the back button, losing browser history, dynamic effects that disappear when the page is refreshed, and more
* advanced css effects, including drag-and-drop scrollbars, pagination, and the use of svg and the canvas object
* mashups—ajax’s ability to combine data from different web services in any number of ways, directly in web pages.
