Just for future reference, it's best to use your mailer's Reply
To All (or "Reply to List") functionality, so that the ML gets
copied. My filters flagged your message as junk and moved it
into my overflowing junk-mail folder because it came to my vim-ML
address but wasn't sent to the list (and you weren't already in a
whitelist of Vim-list folks with whom I occasionally correspond
off-list). Additionally, my vim domain-knowledge only extends so
far. If I don't have the answer, there's a good chance many of
the other smart folks on the list can help you out. Or I may get
something totally wrong. But if you don't CC the ML, you lose
that resource.

Now I'm confused...it sounds like you want to do this in
JavaScript, not vim-script. And it also sounds like you want to
do this on an automated basis, so that every time a row is added,
it cleans up whatever was submitted?
If you have a number of files that need to be cleaned up in one
pass, you can use the argdo/windo/bufdo/tabdo functions to
perform an Ex command across a number of files. Ex commands can
take ranges that give you more surgical-strike capabilities if
you need them, so you can only change ranges of lines if needed.
However, if you have a bunch of files, you can do something like
sh$ cd /path/to/files
sh$ vim *.txt
:set hidden
:argdo %j
(review your files here, and if they're okay, continue)
:wall
That "%j" can be any Ex command, so you can do things like
:argdo 1,10j
to join the first 10 lines of the file or
:argdo g/STARTTEXT/+,/ENDTEXT/-j
to every line after "STARTTEXT" through every line before
"ENDTEXT". If the text to join is embedded in your HTML/JS
files, this might help isolate the contents so you're only
joining germane lines.
