SL3 Javascript GetPlayer() function not defined in HTML5 output

Any updates on this issue?

No change on the custom JS code folks were using in the past. This is a bit further down our roadmap, but we'll share here in the community once we have more information about what this feature will include and when it'll be ready! 

In the meantime, if there are specific things you'd like to see, I'd love to know more about that! You can share it with me here and I'll get it into the hands of our Product team or you can share it with them here. 

Hello Every one,

I am also facing the same issue in our lMS of Storyline 3 output, for the following command "GetPlayer() is not defined" in HTML5.

Any one out there, please help me on this.

Thanks,
Vinod

I've been working on this problem for most of my day today, and thought I'd share my findings.

I have ran a number of unit tests and can confirm that the problem of running a script that calls GetPlayer() from a Storyline object contained in an iframe is 100% reproducible.  This use case always results in the following error:

GetPlayer is not a function

Conversely, when the Storyline object is loaded normally via the story.html file, the GetPlayer() function functions as outlined in the JavaScript best practices documentation.

I have tested this with four different Storyline projects.

Is there any indication of when there might be a resolution to this problem?

Thanks for checking in and sharing your findings, Matthew. There's been no change to the JS code and how it's working in Storyline 3 and 360 just yet. We'll keep you posted if there's any forward movement!

I have tried 10 hours of permutations of window access to access the function, including through the parent, the opener, etc. etc.

I'm reluctant to keep playing with it because it really does feel like it's a bug with Storyline.

Do you have a test link or project that we can look at?

I wrote this a year ago and it's in this thread.  Did you try windows.GetPlayer() ?

"It was the iFrame.  We viewed the page source, pulled the iFrame tag out and pasted that into the browser and the JavaScript worked fine.  Turns out that since it's an iFrame:

window.parent.GetPlayer()  won't cut it.

windows.GetPlayer()  works.

So you might want to share this.  Thanks"

windows.GetPlayer() does not work for me. any other suggestions. I tried window.opener.GetPlayer() and that worked for an html file but not for a js file in same project. 

It seems like there's two different issues going on. 

1) GetPlayer() does not exist yet at the point you're trying to use it

Where you use the GetPlayer() can cause issues. There's a difference between putting the code inside a trigger in Storyline vs. directly in user.js or an external file. This may or may not apply to your issue but:

user.js is loaded early (this is a change from SL2) in the story_html5.html file (around line 105), meanwhile the app.min.js is loaded at the bottom of the file. 

This was a change from SL2. Not sure why this change was introduced but it causes issues.

That means if you put GetPlayer() directly in user.js (even if you're using jQuery and wait until the document loaded), you can get an error because GetPlayer() does not exist yet at that point. Since the file loads earlier than the player is created, it returns an error.

You can test the difference by opening the story_html5.html file and move this line to the bottom.

<script SRC="story_content/user.js" TYPE="text/javascript"></script>  

However, this is a manual effort after each publish. If you put the code inside a trigger in SL, it would run. If that's the case, you know the problem was calling it too early.

2. The iframe discussion

The only time I used parent.GetPlayer() when my JS code was inside a webobject and I had to access the player from an iframe. 

You can check if GetPlayer is a function by using:

if (typeof GetPlayer === 'function') {...}

if (typeof parent.GetPlayer === 'function') {...}
