I'm not sure how else we can approach it?

I have to admit I find the chain of play.php, modules/xerte/play.php and how all that works confusing. It does seem to work when I preview and play though?

Julian,

Not sure if the api_keys solution is going to work out.

The way it's solved now, doesn't work for exported LO's.

Also, there was a small typo in modules/xerte.play.php (Which I fixed), and shouldn't the same code be applied to preview as well?

But I am worried about export. Let me think of a solution there.

No you can't do onload=object.method. Tested it again: they obviously don't treat it as an expression, simply the name of a function. I even tried onload=alert('something'); but it seems it's simply a string, and it's not interpreted.

I know all about setInterval and the like as they were a common feature in the old xerte flash engine, and you couldn't work around them: it could lead to a complete nightmare in some cases. Sometimes a value of 0 was enough to let the value of things take before the next code executed; otherwise - and here's the thing I hate - you basically pick a number and hope for the best. What's to say, that just because 500 m/s is enough on my machine, it's enough on yours? Why are we still in this situation in 2015?

I'm finding some suggested alternativs using $.ajax instead of $.getScript, but am still finding problems, I think they might be firefox specific from what I'm reading.

Yeah, its a pain to have to use timeout but sometimes there is no other way... does using the onload parameter not work?

OK, got it mostly working: you want descriptions in there as well (i.e. below)?

I have to do a window.setTimout to handle the script loading through $.getScript, which gives me the heebie-jeebies, as $.getScript().done() only fires when the script is loaded, NOT when it has executed. I tried the $.ajax alternatives and still had to jump through setTimeout to make it work.

There should be something in the media lesson page's init function that looks to see if the popcorn.js files have already been loaded and only loads them if they haven't been. I could maybe look at the scope stuff tmw

Howdy,

Have you tried adding the script file with the callback as https://apis.google.com/js/client.js?onload=youtuberss.googleApiClientReady

And then defining the googleApiClientReady method as this.googleApiClientReady within the object? You could also load the script using jQuery so that you can check for it already existing rather than load it again on each page model... Fay would probably know how to do this if you aren't sure...

Hi,

I've got the youtube rss working with a hardcode API key. Before we release the code we can split that out and provide a file for people to store their own keys in and read that. I'd appreciate someone peer-reviewing my code: couple of questions:

We need to load the google api which I've done by simply adding...

<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script>

...to the top of the file.

The onGoogleApiClientReady function is defined in global scope so I wondered how to make it part of the youtuberss object, but if I simply define it within the object, it doesn't get called (obviously).

I think Fay or John will have an idea how to make all this nice and graceful! I've committed the file (you'll need an API key!)

Let me know comments,

J
