BroadcastChannel: messageerror event - Web APIs 编辑

The messageerror event is fired on a BroadcastChannel object when a message arrives on the channel that can't be deserialized.

Examples

This code uses addEventListener to listen for messages and errors:

const channel = new BroadcastChannel('example-channel');

channel.addEventListener('message', (event) => {
  received.textContent = event.data;
});

channel.addEventListener('messageerror', (event) => {
  console.error(event);
});

The same, but using the onmessage and onmessageerror event handler properties:

const channel = new BroadcastChannel('example-channel');

channel.onmessage = (event) => {
  received.textContent = event.data;
};

channel.onmessageerror = (event) => {
  console.log(event);
};
