Load a PDF file into a Text Box.

I want to load a PDF file into a Text Box, I found working demo here [view-source:http://checkpointcams.com/test/test.html] but when I download HTML + JS files, and I put in my server when I remove <base href=", and <select> elements, it doesn't work in my project - domain. Can someone modify demo HTML and js files to make this HTML run on all domains /offline mode, without that base href and select elements?
I think this problem is related to a file called "script19.min.js" which needs to be modified.

All that I need is, this simple working Html file + [ js files], Text Box and Upload / Load button.
I know that only real programmers can solve this problem,
Thank you

 

Thanks for your reply ,
it looks like in jsfiddle, it doesn't work but in demo its work great
here you have , https://jsfiddle.net/m2wpqakt/

 

Well I found a few problems.

In the html part you include files via http and jsfiddle is served via http. So I changed them to https but then then the problem is that the site where they are being loaded from doesn't have a valid ssl certificate so the js files can't be loaded.

So I wanted to look at the files in the browser and they don't exist so doesn't matter if it is http or https the files don't exist.

Unless I have done something completely wrong.
