LC makes it easy... Works for me on Mobile also.

In LC do this once.
set the javascriptHandlers of widget "MyBrowerWidget" to "LCHandlerName"

Create this handler:

command LCHandlerName pNum
answer pNum
end LCHandlerName

Subject: JavaScript-Livecode integration question

Dear LiveCode programmers.

I have a question about the Livecode-Javascript integration.

I love LiveCode, but IMO I think CSS+HTML+JS are better technologies for styling applications (it is just a personal opinion).

So, I'm trying  to create Deskops apps using JS+HTML+CSS for the "front" 
and LiveCode for  the "back-end".
I'm using the CEF embedded browser.

My idea is to create something like Electron or NW.js but using Livecode.

Note that I'm talking about Desktop apps, not Web apps.

I have managed to send data from Livecode to JavaScript using the instruction  "do "document.getElementById -xxxxxx" in widget "Browser", but I'm stuck doing the opposite.
My idea is to send an event or data from the CEF to Livecode when someone press a button on the CEF embedded browser.

I found the documentation confused and I'd like to have, if it is possible, a real example about how to do that.

Another question: Does it works on Android/Apple? I'm afraid it won't work

Thanks a lot.

PS: I'm going to try to answer you guys as soon as possible, but sometimes I have to read your responses on the use-livecode mail list archives , because our mail server has the ugly habit of blocking some emails that come from the list.
