I have this a link that contains information about what food is being served at a school each day:
https://nobilis.nobles.edu/skyworld/castlemenu.php?
How do I execute this url in javascript and parse the result?
Please let me know if I need to clarify further. I have been unable to find any information about how to do this and any help would be greatly appreciated!
Unless it is an API designed for you to call to it, you really don't do that. If you could just go to any URL and put the info where you wanted it, well there would be no unique sites. If they want to share the results with you they need to make a system designed for you to access it. Either via a high level API or feed you a JSON or a RSS feed.
You could slip it into a frame or something, but if you have access to that site I would encode and decode myself some JSON and pass it.
