How to throw a JavaScript alert when connection to LMS is lost?

Question

I've been through all the JS, and I still cannot find a place where I can detect whether or not the connection to the LMS is lost (API).

I can throw an error when it initializes - that's no problem. But I want to be able to throw an alert when the connection is lost while the SWF is playing.

Has anyone done this?

Thanks!

I don't think that there is any "stock" function that does that so you would need to write it yourself.

You could probably achieve it by writing a function that will check for a value in the LMS and if that fails then display your alert. Pick a SCORM field that you are sure contains data and the fetch the data through JavaScript. If it returns a value then do nothing but if it doesn't return a value then display the alert.

Trouble is that you would either need to make the funtion run a timed loop or call it manually from each of your slides (perhaps on slide enter or slide exit).
