Many organizations now offer web-based applications that rival local applications in their functionality and user interface. Ajax plays a key role in most of these applications. Ajax is not a specific technology as much as a collection of techniques that allows a web developer to dynamically update the currently displayed page with data retrieved from the server.
Manta Technologies Inc. announces the availability of a new course Ajax Programming. This example-driven course provides a System i programmer with the skills needed to implement an Ajax application.
The course begins by describing the short history of Ajax and showing examples of the types of things you can do with Ajax, from Google maps to Manta's course presentation system. It then describes the one new technology that makes Ajax possible, JavaScript control of the HTTP request object.
The course then shows multiple, increasingly complex examples of Ajax in action. You will see how to pass parameters to a server and receive data in the form of character strings, HTML fragments, or XML. You will also see how to incorporate data into a web page dynamically, adding elements like tables and pull-down lists that are built from data retrieved from the server. Several special situations are covered, including encoding parameters, passing data as XML, and using XML DOM methods to build HTML elements dynamically.
The course ends with a comprehensive example that uses what you have learned to implement "auto completion" for an input field.
Like all Manta courses, Ajax Programming is available in two ways. You can install the course on a PC or take the course through MantaNow, Manta’s Internet-based delivery system. Prices for the course start at $110 for a one-year, single-user MantaNow license or $179 for a CD license.
This course is available automatically to customers who have purchased the entire iSeries Training Library, either for CD delivery with the optional maintenance plan or for MantaNow delivery. It is also available to MantaNow users of the Program Development Combination Pack, the Web Development Combination Pack, and the eBusiness for System i Programmers series.
