Introduction
Computer books
Crazy Ajax handouts (version 3rd) -- jquery/ext js/prototype/DWR enterprise application front-end development practices: Version 3rd of crazy Ajax handouts, where jquery is upgraded to version 1.8; upgrade prototype to version 1.7.1 and DWR to version 3.0. The biggest update of version 3rd provides a detailed and comprehensive introduction to ext JS 4.1. Because ext JS 4.1 has a lot of content, this book takes hundreds of pages to introduce the functions and usage of ext JS. This part of content can be used as an independent learning manual for ext JS 4.1.
Crazy Ajax handout (version 3rd) -- jquery/ext js/prototype/DWR enterprise application front-end development practices "describes the usage of jquery 1.8, ext JS 4.1, prototype 1.7.1, and DWR, the four most commonly used Ajax frameworks, A practical case is provided for each framework, which allows readers to relate theory to practice. This part is the standard handout of "crazy software education center". It not only contains the key points and difficulties of actual Ajax development, but also integrates the learning experience and insights of a large number of learners. Based on the rich teaching experience, I will introduce them in a simple way and hope that the readers can grasp the essence of Ajax development. This book provides two comprehensive cases: the blog system and the electronic auction system, allowing readers to apply what they have learned to practical projects. The electronic auction system is a system with five tables and complex association ing between tables. This case uses the most popular and standardized lightweight Java EE architecture, divide the entire application into the domain object Layer, Dao layer, and business logic layer, and then use DWR as the Ajax engine to call the business logic method to respond to asynchronous requests. The system permission check is postponed to the business logic layer, the HTTP session is used to track the user's operation status, so as to avoid loss of browsing status caused by refreshing the browser. This case has excellent Guiding Value and reference significance for the actual project. This case not only provides the IDE-independent, ant-managed project source code, but also provides the Eclipse IDE-based project source code to meet the reader's needs to the maximum extent. If you encounter any technical problems when reading this book, you can log on to the http://www.crazyit.org to communicate with the book's huge readership.
Crazy Ajax handout (version 3rd) -- jquery/ext js/prototype/DWR enterprise application front-end development practices "is not intended for readers with no basic knowledge, the book no longer contains knowledge about HTML, CSS, and JavaScript, which is the basis for reading this book. This book is suitable for readers with preliminary HTML, CSS, and JavaScript basics, or developers who are not familiar with enterprise application front-end development. If you have mastered the first part of this book: Crazy HTML 5/CSS 3/JavaScript handout, it will be very suitable for reading this book.
