The FoozleTimer
class is wired with a BroadcastChannel
instance, yet when the emit()
method is called, the postMessage()
method is not available. This throws an error:
Uncaught TypeError: this.channel.postMessage is not a function
The emit()
method is called from the startTimer()
method, which uses an arrow function so the this
context should be respected from the FoozleTimer
class. However, this does not appear to be the case.
It is possible that the context of the BroadcastChannel
instance is not being retained correctly.
To resolve this issue, further debugging is needed to confirm the source of the issue. Some potential solutions might be:
- Ensuring the context of the
BroadcastChannel
instance is set correctly in the constructor ofFoozleTimer
- Re-initializing the
BroadcastChannel
instance within theemit()
method
