jQuery Mobile on Filemaker Go?

[typewriter]

I posted this one earlier on a different part of this forum, but it be more appropriate here.

Until recently, I have used jQuery and the jQueryUI slider widget to display a slider in FileMaker Pro (v17-18-19). This works fine but now I also need to have it work on FileMaker Go, so I tried my luck on jQuery Mobile 1.4.5. Not a very modern product (2017) but as long as it does what it promises... The slider Widget of jQuery Mobile is working nicely on FileMaker Pro, but not on FmGo 17, 18 or 19: it doesn't load, keeps displaying a spinning logo. When I publish the HTML page on a website and open it in Safari Mobile the slider works fine. Any help appreciated!
