Description

Ajax can bring many advantages to an existing web application without
forcing you to redo the whole thing. This book explains how you can add Ajax
to enhance, rather than replace, the way your application works. For instance,
if you have a traditional web application based on submitting a form to update
a table, you can enhance it by adding the capability 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 more
interested in extending existing applications than in creating Rich Internet
Applications (RIA). 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:

developing a strategy for changing your site before you sit down to code

object

losing browser history, dynamic effects that disappear when the page is
refreshed, and more
Covers advanced CSS effects, including drag and drop "scroll bars",
pagination, and the use of SVG and the Canvas object

pages
