AJAX: Creating Web Pages with Asynchronous JavaScript and XML

EBook Description: The Easy, Example-Based Guide to Ajax for Every Web Developer Using Ajax, you can build Web applications with the sophistication and usability of traditional desktop applications and you can do it using standards and open source software. Now, for the first time, there�s an easy, example-driven guide to Ajax for every Web and open source developer, regardless of experience. Edmond Woychowsky begins with simple techniques involving only HTML and basic JavaScript. Then, one step at a time, he introduces techniques for building increasingly rich applications. Don�t worry if you�re not an expert on Ajax�s underlying technologies; Woychowsky offers refreshers on them, from JavaScript to the XMLHttpRequest object. You�ll also find multiple open source technologies and open standards throughout, ranging from Firefox to Ruby and MySQL. You�ll not only learn how to write �functional� code, but also master design patterns for writing rocksolid, high-performance Ajax applications. You�ll also learn how to use frameworks such as Ruby on Rails to get the job done fast. * Learn how Ajax works, how it evolved, and what it�s good for * Understand the flow of processing in Ajax applications * Build Ajax applications with XML and the XMLHttpRequest object * Integrate back-end code, from PHP to C# * Use XSLT and XPath, including XPath Axis * Develop client-side Ajax libraries to support code reuse * Streamline development with Ruby on Rails and the Ruby programming language * Use the cross-browser HTML DOM to update parts of a page * Discover the best Ajax Web resources, including Ajax-capable JavaScript libraries About the Author EDMOND WOYCHOWSKY, a senior level consultant in Pennsylvania and New Jersey, specializes in client-side JavaScript, Java, Oracle, open source, and Microsoft technologies. A well-known contributor to TechRepublic, he has developed applications for the financial, pharmaceutical, and manufacturing industries. He began his professional career at Bell Laboratories.

More and more Web sites are being rewritten as Ajax applications; even traditional desktop software is rapidly moving to the Web via Ajax. But, all too often, this transition is being made with reckless disregard for security. If Ajax applications aren�t designed and coded properly, they can be susceptible to far more dangerous security vulnerabilities than conventional Web or desktop software. Ajax developers desperately need guidance on securing their applications: knowledge that�s been virtually impossible to find, until now.
Ajax Security systematically debunks today�s most dangerous myths about Ajax security, illustrating key points with detailed case studies of actual exploited Ajax vulnerabilities, ranging from MySpace�s Samy worm to MacWorld�s conference code validator. Even more important, it delivers specific, up-to-the-minute recommendations for securing Ajax applications in each major Web programming language and environment, including .NET, Java, PHP, and even Ruby on Rails. You�ll learn how to:

� Mitigate unique risks associated with Ajax, including overly granular Web services, application control flow tampering, and manipulation of program logic
� Write new Ajax code more safely�and identify and fix flaws in existing code
� Prevent emerging Ajax-specific attacks, including javascript hijacking and persistent storage theft
� Avoid attacks based on XSS and SQL Injection�including a dangerous SQL Injection variant that can extract an entire backend database with just two requests
� Leverage security built into Ajax frameworks like Prototype, Dojo, and ASP.NET AJAX Extensions�and recognize what you still must implement on your own
� Create more secure �mashup� applications

Ajax Security will be an indispensable resource for developers coding or maintaining Ajax applications; architects and development managers planning or designing new Ajax software, and all software security professionals, from QA specialists to penetration testers.

Ajax Hacks: Tips & Tools for Creating Responsive Web Sites

Ajax, the popular term for Asynchronous javascript and XML, is one of the most important combinations of technologies for web developers to know these days. With its rich grouping of technologies, Ajax developers can create interactive web applications with XML-based web services, using javascript in the browser to process the web server response.
Taking complete advantage of Ajax, however, requires something more than your typical "how-to" book. What it calls for is Ajax Hacks from O'Reilly. This valuable guide provides direct, hands-on solutions that take the mystery out of Ajax's many capabilities. Each hack represents a clever way to accomplish a specific task, saving you countless hours of searching for the right answer.

AJAX Web Development

Ajax is an acronym f Asynchronous javascript and XML, and at its heart is the XMLHTTPRequest object, which is part of the XML DOM (Document Object Model)

AJAX and jQuery

Description
You want to create an AJAX application. Why would you use Django? Why would you use jQuery? Why would you use both together? Enter Django JavaScript Integration: AJAX and jQuery � your comprehensive answer to all these questions and the only extensive, practical, and hands-on guide to developing any AJAX application with Django and jQuery.

Gone are the days when you used to lament over the lack of official documentation on AJAX with Django. This book will teach you exactly why Django is called �The web framework for perfectionists with deadlines�, how jQuery � the �write less do more� JavaScript library � is practically a virtual higher-level language, and why they both deserve to be integrated with AJAX.

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�.

You will cover the basics of AJAX; use jQuery, the commonest JavaScript library, on the client side, and learn form validation with an eye to usability, build things with Django on the server-side, handle login and authentication via Django-based AJAX, and then dip into the rich jQuery plugin ecosystem to build in-place editing into your pages. You will add auto-complete functionality courtesy of jQuery UI, easily build forms with Django ModelForm, and then look at a client-side search implementation that can look things up without network access after initial download. You will learn to Implement a simple, expandable undo system, and offer more full-blooded account management, tinker, fix some bugs, offer a more usable way to handle password input, add local time support for people who are not in your time zone, look at usability, and finally take a look at debugging.

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
* Embed JavaScript in Django templates
* 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
* Minify JavaScript files and also learn the pros and cons of doing so

Approach
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.

Professional Ajax

provides a developer-level tutorial of Ajax techniques, patterns, and use cases. The book begins by exploring the roots of Ajax, covering how the evolution of the web and new technologies directly led to the development of Ajax techniques. A detailed discussion of how frames, JavaScript, cookies, XML, and XMLHttp requests (XHR) related to Ajax is included. After this introduction, the book moves on to cover the implementation of specific Ajax techniques. Request brokers such as hidden frames, dynamic iframes, and XHR are compared and contrasted, explaining when one method should be used over another. To make this discussion clearer, a brief overview of HTTP requests and responses is included.

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)
* My page has so many links managed by JavaScript, and I am loosing control, help me make this more organized! (Decoupled Navigation 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)
