AbstractWorker 接口在 Web 工作者 API is an abstract interface that defines properties and methods that are common to all types of worker, including not only the basic Worker , but also ServiceWorker and SharedWorker . As an abstract class, you don't directly interact with AbstractWorker .

特性

AbstractWorker interface doesn't inherit any properties.

事件处理程序

AbstractWorker.onerror

EventListener which is invoked whenever an ErrorEvent 类型 error bubbles through the worker.

方法

AbstractWorker interface doesn't implement or inherit any methods.

范例

As an abstract interface, you won't directly use AbstractWorker in your code. Instead, you'll interact with either Worker or SharedWorker , both of which inherit the properties of AbstractWorker .

This code snippet demonstrates the creation of a new Worker 使用 Worker() constructor; it also shows how to then send a message to the worker.

var myWorker = new Worker('worker.js');
first.onchange = function() {
  myWorker.postMessage([first.value, second.value]);
  console.log('Message posted to worker');
}
					

The worker's code is loaded from the file "worker.js" . This code assumes that there's an <input> element represented by 第一 ; an event handler for the change event is established so that when the user changes the value of 第一 , a message is posted to the worker to let it know.

You can find more examples on the MDN Web Docs GitHub repository:

• Basic dedicated worker example ( run dedicated worker ).
• Basic shared worker example ( run shared worker ).
