non normative file name. click_link_interaction.js ... and, where's the .py
file? And the unit test for the interaction to show that it is working?

[marja, 2012/11/06 16:01:21]

There is no .py; test_helper_interaction.py (which I renamed to
javascript_runner_interaction.py) dispatches to all these files, and thus the
non-standard file name.

"clickLink" in the .json -> load interaction_clickLink.js and call
window.__clickLink(json_object).

But I see in another comment that you already used "click_link" as a name for
the action, so I can instead dispatch like this:

"click_link" in the .json -> load interaction_click_link.js and call
window.__click_link(json_object).

That'll create a nonstandard js function name, but I think it's nicer to have
that than to have the "click_link" <-> "clickLink" dispatching step somewhere.
Wdyt?
