Also if you are running a program you can take a peak at the browser debugger by pressing f12. You can see the bit of JavaScript used to pass variable back and forth and trigger those functions manually.

Been trying but get no results.
I was trying to do something like this:

Code: Select allx = 10
button "change", [change]
button "end", [progend]
textbox x

wprint |<!DOCTYPE html>|
wprint |<html>|
wprint |<body>|
wprint |<script>|

wprint |var a = 10 * x|

wprint |</script>|

wprint |</body>|
wprint |</html>|
wait

[change]
x = a
print a
print x
wait

[progend]
end
wait



so first I declare x in basic
next in javascript I say a = 10 * x
and then in basic I print a and x

did not work. Any example please ???
An example for sending a variable to javascript and an example for retrieving a variable from javascript would be great.
