The JavaScript code below is not loading, in the JavaScript console it says,
"Not allowed to load local resource:"
Javascript:
(function () {
var script = document.createElement('script');
script.setAttribute('src','file:///home/chronos/u-1dd073c6b7b8430c0010c7429b07db331325c324/Downloads/Core/tube.js');
document.body.appendChild(script);
}()
);
This stuff is mostly pasted from other questions but perhaps you will find it useful:
Check if your host is fully qualified in here
You can also read a guide in here
Some browsers, like modern versions of Chrome, will even refuse to cross from the http protocol to the file protocol. Chrome and Safari seem to use a more strict implementation of sandboxing (for security reasons) than the other two.
Finally, you shouldn't load javascript files off a local filesystem. You need to have it hosted with your app and load it off the web server.
Create a python server using
python3 -m http.server 8086
and replace the
file:///<PATH_TO_FILE>
with https://localhost:8086/<RELATIVE_PATH_TO_FILE>
