DedicatedWorkerGlobalScope: messageerror event

在此页

messageerror event is fired on a DedicatedWorkerGlobalScope object when it receives a message that can't be deserialized.

Listen for messageerror 使用 addEventListener() :

// inside worker.js
self.addEventListener('messageerror', (event) => {
    self.postMessage('Error receiving message');
    console.error(event);
});

一样，但使用 onmessageerror 事件处理程序特性：

// inside worker.js
self.onmessageerror = (event) => {
    self.postMessage('Error receiving message');
    console.error(event);
};
