AJAX and jQuery
This hands-on-guide shows you how to put Django and jQuery together in the process of creating an AJAX application. In this book, they are brought together in a real-world scenario, with attention to usability, to build and develop an AJAX application.
The first two chapters provide a short and necessary introduction to the world of Django, jQuery, and AJAX; and the remaining chapters are based on a case study that will make you realize the immense potential and benefits of integrating Django and jQuery with your AJAX application.
By the time you are done with this book, you’ll be developing your AJAX applications with Django and jQuery in less time than you can say “integrate”.
After working through this book, you will have both an AJAX application and a deep understanding that you can use to customize, extend, and further develop it in your organization.
This book has been written and tested for Django v 1.2.3 and jQuery v 1.4.4.
What you will learn from this book :
* Learn how and why, for certain kinds of web development, Django is more ‘Pythonic’ than Python
* Understand whet the XMLHttpRequest Object is and how to implement it in various browsers
* Learn account creation and login creation using AJAX
* Build forms using Django models
* Embed jQuery auto-complete plugins in your Django templates
* Validate form input on the server side using AJAX
* Integrate jQuery sliders into your Django template
This book will teach you how to enrich your AJAX applications with Django and jQuery in a practical manner with minimum fuss. It introduces AJAX basics, gets a little deeper, and then goes chapter-by-chapter through a carefully chosen case study. It demonstrates how different pieces of a Django AJAX application work in themselves and are put together and specifically leads you through building an intranet employee photo directory with social networking features.
Once a basic understanding of the various request types is discussed, the book moves on to provide in-depth examples of how and when to use Ajax in a web site or web application. Different data transmission formats, including plain text, HTML, XML, and JSON are discussed for their advantages and disadvantages. Also included is a discussion on web services and how they may be used to perform Ajax techniques. Next, more complex topics are covered. A chapter introducing a request management framework explores how to manage all of the requests inside of an Ajax application. Ajax debugging techniques are also discussed.
The last part of the book walks through the creation of two full-fledged Ajax web applications. The first, FooReader.NET, is an Ajax-powered RSS reader. The second, called AjaxMail, is an Ajax-enabled email system. Both of these applications incorporate many of the techniques discussed throughout the book.
The MS Ajax 4
AJAX is an exciting Web platform for many reasons. Using AJAX, many tasks that were traditionally performed on the server happen in the browser instead, resulting in fewer round-trips to the server, lower bandwidth consumption, and faster, more responsive Web UIs. While these outcomes are the result of offloading a good deal of work to the client, the browser still isn’t the environment of choice for many developers who would rather have the full power and flexibility of server apps at their disposal.
Ajax Patterns and Best Practices
Ajax Patterns and Best Practices
Ajax is taking us into the next generation of web applications. Ajax has broken the client-server barrier by decoupling the client from the server, but an Ajax application still needs a server to extract content from. The most effective use of Ajax and the server requires an understanding of REST, an architectural style used to define Web services.
Ajax Patterns and Best Practices explores dynamic web applications that combine Ajax and REST as a single solution. A major advantage of REST is that like Ajax, it can be used with today's existing technologies.
This is an ideal book whether or not you have already created an Ajax application. Because the book outlines various patterns and best practices, you can quickly check and verify that you're building an efficient Ajax application.
Inside the book, the patterns will answer the following questions:
* What is Ajax, and REST and why do you even care? And if I should care what are some examples of websites that make effective use of Ajax and REST?
* What are the absolute basics of Ajax and REST and what parts of those basics should I use?
* How should deal with large amounts of data? Should I cache the data? Should I get the data piece fed to me? (Patterns: Cache Controller, and Infinite Data)
* People keep telling me that sessions and cookies are bad? Are they bad? What should I do? And while I think about how about generating content for other devices? (Permutations pattern)
* I want to fix the back-button problem of the HTML browser. (State Navigation pattern)
* What is the best way to create a mashup? (REST Based Model View Controller pattern)
* I understand that HTTP means I send data to the server, how about the server sending me some data without asking for it? (Persistent Communications pattern)
* My server side code looks like a mess with tags and code pieces everywhere how can I organize and make my HTML page behave like a SOA client and use REST based web services? (Content chunking pattern)
