Help ! JS compatibility

Question

@Mofey warned me that the following code doesn't work on his device.

https://code.sololearn.com/W3nSks69Enk3/#js

I wrote it on pc, and it's ok on both chrome and firefox, so i have two questions:
- how can i solve this kind of recurring troubles while writing web codes ? Is there some kind of multi-emulator ?
- Do you know what's wrong with this code ? Mofey first mentioned : line 48, Vex not defined ... I thought i fixed it.

Thank you : )

Answer 1

its a wild guess, but it looks like the package isnt loaded properly. maybe a connection problem with the cdn server and his device.

that, or the vexflow feature isnt compatible with his browser/webview. if this the case open the code in updated major browser like chrome or firefox (or update the webview) will solve it

Answer 2

Taste
Thank you 😊
Ok, so in that case, there's nothing I can do in my code ?

Answer 3

other than try to change the cdn server.

but maybe someone else has different opinion
