Answer 1

1: you don't need a special JavaScript var for this, you can track it in you sketch until you need the result on your page.

2: make your sketch tell javascript what to do when you click - see http://processingjs.org/articles/PomaxGuide.html#interface on how to make a sketch and javascript talk to each other while keeping your code runnable on both the web and in the Processing IDE
