Using Javascript for background music audio

Hi Robert,

The javascript element isn't something I can help with - but I know we've got a number of community members who have created a similar set up. You may want to reach out to folks in either of these discussions:

• Background Music Demo
• Background music in Storyline 2

Hope that you find the help you need! 

On your video slide (slide 2) add an execute javascript trigger on timeline start.

var audio = document.getElementById('bgSong');
audio.pause();

When you want to resume the background music use the following javascript

var audio = document.getElementById('bgSong');
audio.play();

Thanks for the speeding response all! I understand the first part, Russell. When I want to resume audio on slide 3 would I input the second javascript or do I include both of those in slide 2?

I would put the pause script on slide 2.

var audio = document.getElementById('bgSong');
audio.pause();

And then modify the script on slide 3 to:

//load the scripts dynamically into the head of the document
function add_line() {
var line = document.createElement("audio");
var head=document.getElementsByTagName('body')[0];
line.type = "audio/mp3";
line.src="SpaceJazzEdit.mp3";
line.id="bgSong" ;
line.autoplay = true;
head.appendChild(line);
}

//but we only want to add these once!
if(document.getElementById('bgSong')==null){
add_line();
var audio = document.getElementById('bgSong');
audio.volume = 0.5;
}else{
var audio = document.getElementById('bgSong');
audio.play();
}

Russell, thank you very much for your help and for the learning experience. I couldn't have done it without you and this community. 

Hi, would it be possible for me to stop one audio file at the end of a scene and launch another audio file in a new scene so that I would have different background music for each scene?

Ardiannie - Looks like I'm about a year late answering your question, but yes you can do that by just assigning each song a different line id.  For example, instead of using "bgSong" for each audio file, use bgSong1, bgSong2, etc.  Just make sure you pause the first audio before playing the second using the code that Russell posted on his first response.
