Overview
Dojo is a library that extends the JavaScript language to simplify the manipulation of the Document Object Model (DOM) and enhances JavaScript for robust object-oriented programming. This course explores using Dojo to manipulate the DOM in real time while the user is interacting with the program. Providing menus, switching user views, moving graphic objects in real-time, updating views in real-time using AJAX and other concepts are all addressed. Leveraging object-oriented principles to build reliable, robust applications in JavaScript using the Dojo extensions are explored in detail. The Dojo widget environment to build client applications from widgets (client-interface components) is used in-depth.
Audience
This course targets developers who want to learn how to leverage Dojo for building advanced JavaScript applications (Rich-client applications) and programming managers who need to understand what their teams are doing.
Prerequisites
A working knowledge of HTML, experience with JavaScript in HTML documents and experience with object-oriented programming concepts.
