Lotus Domino Designer 8: JavaScript

Description:
During this course you will use Domino Designer 8 to add JavaScript to Domino applications that are accessed by browsers. The course covers the basic language elements of JavaScript, how to add scripts using Domino Designer, and how to exploit the various browser and language object event handlers. There is a strong emphasis on the browser object model and how it relates to the Domino object model. The course also touches on how to incorporate Dynamic HTML, Java Applets, LiveConnect, ActiveX controls, and AJAX into web-based applications.
  • Cost: Price on application
  • Duration: 3 days
  • This course is not available as part of our public schedule but can be provided on a customised client specific basis.
