I'm trying to get two iframes to communicate, with little luck. I think postMessage()
or Message Channel API (are they one & the same?) is the way to go, but I don't control the parent window.
In other words, the structure is this:
[parent window (user's website)]
[iframe 1 (my app)]
[iframe 2 (my app)]
I know this is possible because SoundCloud does it (if you have one embedded player playing, and you click play in the second one, the first one pauses).
How can I achieve this?
EDIT: This solves it.
