you might be surprised at the restrictive handeling of the WD4A framework when it comes to the manual integration of javascript. This restriction was introduced in order to enable the WD4A applications to support emerging client technologies that don’t use javascript for client-side flow control.
Sound knowledge of object oriented ABAP programming is a must for understating WD4A concepts. A number of technologies like HTTP, HTML, CSS, XML and client side scripting etc are integrated in WD4A applications.
These technologies are encapsulated and details of these are not shown to you when you use the WD4A framework for web application so that you can focus more on the business process and implementing it rather on the intricacies of these web development technologies. That is the magic of WD4A framework.
To clearly understand WD4A framework, one should know the following :
Communication process in HTTP and HTTPs ie the request response cycles.
Programming in a distributed development environment.
Difference between client side and server side scripting
Use of design patterns in programmingRelated Articles :
