This script aims to give the basic set of instructions for each type of action in JArchi. Useful to begin when language or function library details are implicit or described very quickly in the documentation. Can be used to build scripts by copy/past/adapt or as a memo for some use cases or functions that you do not meet so often.

There are still one or two unsolved topics. And it can very probably be improved in many ways, contributions are more than welcome. I just want to keep it simple, readable and straightforward for beginners even if there may be smarter shortcuts.

Thank you, very useful.
Maybe a suggestion for an update: how do we access an element on a view, knowing only the view name and element name, and not their ID? Various $(".myView").xxx().etc() attempts all failed. Is there a more direct way than looping through all element on the view:

$(".myView").find().each(function(o) if o.name = "myElement" then GotIt)

Thank you.
