Focusing on the last few functions you'll see properly worded websocket send prompts, the issue being that either after the variable id has changed manually by the user or just the selected option in the select element changes by the user, the w.send command no longer sends anything and as far as I can tell it is only returning undefined.

I've tried a few ways around this yet none of them have worked so far, it's odd as this issue only seems to occur when sending a similar string with different information in the variable, through the web console I can send messages still, but only ones that aren't similar to the ones in the functions. I could be missing something obvious so I decided that asking about it here might be for the best. In case it's hard to tell what I'm trying to accomplish, I'm working with the cc: tweaked minecraft mod and making a connection to it via node js and an ngrok tcp server, on the web end I need to be able to take the list of computers I compile in the select element and select which option I'd like to send a message to. The most odd part though is that while it won't send messages if I interact with the select box, if the first select option disappears and a new one then is put into id it usually works without any issue. Also I'm sorry if this is an unpleasing read, it's my first time on stack overflow.

I've solved my problem, several errors were found in my websocket host. I happened to forget I'd arrayed my object that was used to collect the uuids soo I ended up sending a message that wouldn't get through the if statement and if it did it wouldn't actually send anything, sorry for the trouble.
