Thank you for your response. I had actually already reviewed both the "Element Javascript" and the "Element Javascript (Advanced)" articles in the wiki pretty thoroughly, and unfortunately I was unable to find any indication where the element javascript code is located or example code that is relevant to my needs; ie, how to create custom javascript actions to "slide in" and "slide out" one element based upon various conditions in another element (I know there there are presets for this, but as mentioned above, I am trying to find a way to consolidate the actions rather than have a huge list of individual condition tests/js actions).
I have also searched in the database in the "fabrik_jsactions" and "fabrik_elements" tables, as well as the tables pertaining to the specific lists where my created elements that have javascript actions are saved. In "fabrik_jsactions" there is a column for "parameters" that does contain the parameters for the various js actions I have set, but there is no complete coding there.
I have also searched through the forums and so far have not found code samples relevant to my needs. I thought there might be someone who at least periodically monitors this forum who might be able to give a simple -- "the file is named 'abc.js and is located in such-and-such directory" or "look in the 'xy_z' table in the database" etc. As is clear I am very much still a beginner at all this, and so if anyone has the patience and inclination, some guidance along these lines would be much appreciated! In the meantime, I will keep looking!
