Problem:
Hi, is there a way to play an audio through JS and have the code stop while its doing that? Similarly to the ‘blocking’ checkbox in the AP UI?

Thanks, Rolf

Hi Rolf,

Please check the attached sample to see if it is what you are looking for:
Audio.approj (852 KB)
I use an interactive timeline to control playback of the audio, then add a script to start the timeline with a callback.

Regards,

Thanks a lot Phuong,

your suggestion

    prez.startTimeline("Timeline 1", function (){
        prez.object("PlaybackFinishedMsg").show();
    });

works fine. I would like to just have the name of the function as callback and not the whole function.

So, I tried

    prez.startTimeline("Timeline 1", Message);
    function Message(){
        prez.object("PlaybackFinishedMsg").show()
        };

which works fine, too!

However, I would like to pass the name of the object with the callback, i.e.

    prez.startTimeline("Timeline 1", Message("PlaybackFinishedMsg");  
    function Message(Objektname){
        prez.object(Objektname).show()
        };

Is that possible as well? I don’t get it to work …

Thanks, Rolf

Hi Rolf,

The first line of the code is missing a closing parenthesis. However, by passing a parameter, the callback will be executed immediately which leads to unexpected result.
You can try the following:

prez.startTimeline("Timeline 1", function () { Message("PlaybackFinishedMsg") } );  
function Message(Objektname){
    prez.object(Objektname).show()
};
