Hi guys. Need help with something urgently.

I would like to make a system that when two random people click a button from two completely different devices a song starts playing (the same song)… is that possible…How can I do it…please help!

Not enough input.

Plus, if this is all random, then how are the users going to know that they are playing the same song as somebody else, especially if they are not in the same place?

Elaborate more on your idea and how you are wanting the same song to be played on two different devices

You can set up a button that randomises your music choice before playing that random song. See the links below about using Math . floor ( Math . random ().

So to do it with Wix AudioPlayer, use the src() function.

You can see examples here from Stack, that you can work from and change it to suit Wix and javascript on your own site.
