I'm not sure I understand the question exactly, but any JS code would
not go into a CSD file.  Instead, a web page would typically include
the Javascript Csound engine and control it through the API.  You
would write your sound-related code in Csound CSD, then load with the
JS Csound engine and run it. Then, use the API from your JS code to do
things like send values over channels, execute events, read new
orchestra code, or evaluate text as score.

JavaScript code can go into an  element in a CSD file. This will
work in the Csound for Android app and in the development version,
soon to be released, of CsoundQt.

What Steven is describing will work in Csound for Emscripten, Csound
for PNaCl, Csound for WebAssembly, and the development version of
CsoundQt, so this is probably a better way to go.

Mike

Hi,

I saw your other email but I try to answer here as it is probably a bit more 
of the kern problem.

If your device runs Android, you can use Csound for Android already 
https://play.google.com/store/apps/details?id=com.csounds.Csound6&hl=en

and it supports UI-s written in html -  you need to select html based UI 
instead of builtin UI somewhere in settings (sorry, I don't have it bow by 
hand). You can add the html part directly to your csd
see more http://write.flossmanuals.net/csound/h-csound-and-html/

So yo can use write a completey custom GUI using javascript etc for your 
application.

Soon you can use CsoundQt to prepare and run such csd  (or run just html files 
that use csound object), but you don't need it per se. 

CsoundQt is meant primarly for desktop environments and would not build easily 
on Android, I am afraid. I don't know much about ChoromeOS and would be very 
itneresting to find out if CsoundQt can be built on it.

On the other hand you can bypass them both and use Csound for WebaAsembly that 
runs directly in your browser (this is quite new thing and I have not tried 
using it yet)

Examples on:
