I suggest you take a quick look at https://stackoverflow.com/questions/10112509/reading-a-text-file-with-jquery where there is a similar question. — meewog, Jul 31 '20 at 11:17
after you read the contents of the file, you should iterate through each data and create an option for it — meewog, Jul 31 '20 at 11:18

Use "fetch" to load contents of text file:

fetch('http://localhost/VMS.txt')
  .then(response => response.text())
  .then((data) => {
    console.log(data)
  }
