Course Abstract:	This course provides instruction and practical exercises using the ExtJS JavaScript Library. The first day of this course examines the core features of the library which include the important Element object, event handling capabilities, and other utilities such as those for working with arrays, strings, and other data types. The second day introduces ExtJS Ajax capabilities, layouts, Panels, form components, and DataViews and begins to introduce the data-riven components such as TreePanels and ComboBoxes. The third day places heavy emphasis on using the GridPanel, TabPanels, and DataReaders. This day also features hands-on exercises for extending and creating custom components. Discussions on library loading techniques, performing custom builds, and creating custom themes also occur on this last day. This course does not cover JavaScript Fundamentals or any modern practices of JavaScript, such as OO best practices or advanced JavaScript language features. It focuses solely on the ExtJS library.
