Catch slide change in JS

[Robert Bobrowski]

Hello,

How can I catch slide change click from custom JS? I added <script> with my file in BBB and now I need to know when slide has changed and send info to parent window. Eventually how can I get current slide from Viewer page?

I have communication working for moderator in both directions between iframe and parent, I can trigger slide change from parent, save some comments from moderator in external form. Now I want to show changes to viewer and I can ask my server but should be better way as BBB already changes somehow slides...

Thanks,

Robert
