Reading js file from SD card

[SRS-Nick]

I found your video on youTube, which lead me here..

"Load js files and image files from SD card offline"

I am working on a project using an SQLite database located on an SD Card.
I need to be able access the SQLite database online or offline, "no internet".

The following JavaScript works loading the "jquery.min.js" from a URL

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

I downloaded the "jquery.min.js" file and saved it to the SD card and I am trying to use
your technique, see below

<script src="?getfile=/jquery.min.js"></script>

However, I must be doing something wrong, I cannot seem to get this working?

Note: the project code works GREAT, as long as I have internet access, as soon as
I disconnect the internet, I cannot access the SQLite database,

Can anyone help me understand how to use this method?
