Hi Hraban, the sample code will be useful to learn. The documentation I have is: * “Developing Acrobat® Applications Using JavaScript™” * “JavaScript™ for Acrobat® API Reference” Of course, I’m interested in other documents from Adobe.

Hi Pablo, I used JS in Acrobat 7 and still have the documentation and some sample code – I don’t know if Adobe keeps it online. If you like, I can send it to you off list.

Re: [NTG-context] issue with JavaScript in Acrobat
Hi Peter,
many thanks for your explanation.
I’m translating (I mean, I’m trying to translate) a method that worked
perfectly fine with milliseconds in ActionScript 2. This is the main
reason why the transitions are recorded in milliseconds.
The issue that I discovered now is that (even if I call it
“milliseconds”), the time unit variable “msecs” has milliseconds only
when app.setInterval is set to 1.
I don’t know how to use a system clock in JS (or in Acrobat). But this
is only a test to check how it works.
Many thanks for the advice on setting the interval to 10 ms. I realized
that I could divide the transitions by ten and it worked fine. No human
can spot the difference even in 0.1 secs. That simple math operation
wasn’t obvious to me (background in humanities 😅).
Many thanks again for your help,
Pablo

Re: [NTG-context] issue with JavaScript in Acrobat
Hi Pablo
Nearly no experience with JavaScript, no working Acrobat version
installed (no testing possible). So take the following with a grain of
salt...
I guess it's just the too small call interval of the "step_clock"
function. Calling it a thousand times per second doesn't seem to work.
If the function is called a hundred times per second only, your clock
counter is also incremented only a hundred times.
I would use a system clock value instead (difference between start time
and current time), so you can limit the call interval to a more
reasonable value (1/10s).
Regards, Peter

[NTG-context] issue with JavaScript in Acrobat
Dear list,
I have this minimal sample:
\setupinteraction[state=start]
\setupinteractionscreen[option=max]
\startJSpreamble {varia} used now
var transitions = [1000,
2000,
3000,
4000,
5000,
6000,
7000,
8000,
9000];
var msecs = 0;
function step_clock() {
try { ++msecs ;
if ((msecs >= (transitions[this.pageNum]/10)) && ( this.pageNum
< this.numPages )) { ++this.pageNum; };
} catch (e) {}
}
advance = app.setInterval ("step_clock()", 1);
advance.count = 0;
\stopJSpreamble
\starttext
\dorecurse{10}{\startTEXpage[pagestate=start, offset=1em]
\pagenumber
\stopTEXpage}
\stoptext
Acrobat is required. And I have an issue with it
Each slide takes a full second (1000 milliseconds). But the conditional
in step_clock() needs to divide the elements from transitions array by
ten. Otherwise it is ten times slower.
Am I missing something here? Or why is "step_clock()" ten times slower
than it should be?
Many thanks for your help,
Pablo
