Web Development

I'll try to make this as short as I can, but with enough info to make sense. Be warned, I am not a programmer or developer by any means. I'm just a hobbyist who spends a lot of time trying to learn on my own.

I'm looking to save "https://scorecount.com/tennis/" locally on a PC so that it can be used offline. I've done the normal "right click, save as" routine in both Firefox and Chrome, which saves the main page (I save it with the name "tennis") as well as a similarly named folder that contains the js, css, and image files. (so, in my case... "tennis.html" and a folder called "tennis_files")

When I try open the tennis.html file, my browser eventually gets to a "we're having trouble finding that site" message. The URL it's trying to reach in the URL bar is "https://driveLetter/path/on/local/drive/tennis.html", instead of the more expected "file:///driveLetter/path/on/local/drive/tennis.html".

I believe I've narrowed this down to something in the tennis.js file (which gets renamed to "tennis.js.download" when I save the page locally). If I remove this file, the page loads, but of course it doesn't actually work. I think something in there is redirecting the URL, but now that the file is saved locally the path it's creating and trying to reach doesn't work.

I've tried going through the js, deciphering all of the array references as best I can, but I'm not able to figure out where this is happening. I'm hoping someone can throw me a lifeline. Thanks in advance!
