This intensive, 4-day core Ajax training course teaches a scalable way of writing robust, user-friendly, and secure Ajax solutions for the Enterprise. The course starts by introducing Ajax from a business, design, and coding perspective. Then, the course looks at Ajax and the network, considers HTTP traffic patterns, object serialization across HTTP, and management and measurement of HTTP traffic. You will also learn about reverse Ajax and Enterprise Comet. You will then be introduced to the impact of Ajax on the user interface, prototype, and some important data validation patterns. You will also learn how to use event-driven code and callback functions and Scriptaculous. Then, you will discuss Ajax within the context of your Enterprise Architecture. You will learn how Ajax works with SOAP and REST web services and how to use mash-ups to interact directly with third-party web services. Finally, you will learn how to look after your code, with unit testing and functional testing using jsUnit, TestMaker, and Selenium.
