Secondary Question: Anyone ever use jQuery.ajax in a client-side? Basically, when someone 'checks' a checkbox I wnat to make an ajax call, and based on its response 'check/uncheck' the same checkbox.

What would be the the advantage of using jQuery over

N/https

? I wouldn't rely on NetSuite's version of jQuery, which they are free to remove (like they did with jQuery UI) or change the version (like they just did in 2019.2) of at any time.
