当 {{domxref('Worker')}} 对象接收到一条无法被反序列化的消息时， messageerror 事件将在该对象上被触发。

是否冒泡 否
是否可取消 否
接口 {{domxref("MessageEvent")}}
对应事件处理属性 onmessageerror

例子

创建一个 worker ，使用 addEventListener() 监听 message 和 messageerror 事件：

// inside main.js

const worker = new Worker("static/scripts/worker.js");

worker.addEventListener("message", (event) => {
    console.error(`Received message from worker: ${event}`);
});

worker.addEventListener("messageerror", (event) => {
    console.error(`Error receiving message from worker: ${event}`);
});

同样，可以使用 onmessageerror 事件处理属性监听事件：

// inside main.js

const worker = new Worker("static/scripts/worker.js");

worker.onmessage = (event) => {
    console.error(`Received message from worker: ${event}`);
};

worker.onmessageerror = (event) => {
    console.error(`Error receiving message from worker: ${event}`);
};
