AbstractWorker

The AbstractWorker interface of the Web Workers API abstracts properties and methods common to all kind of workers, being Worker or SharedWorker.

Properties

The AbstractWorker interface doesn't inherit any property.

Event handlers

AbstractWorker.onerror

Is an EventListener that is called whenever an ErrorEvent of type error bubbles through the worker.

Methods

The AbstractWorker interface doesn't implement or inherit any method.

Example

Note that you won't be using the AbstractWorker Interface directly in your code — when called, Worker and SharedWorker inherit its properties. The following code snippet shows creation of a Worker object using the Worker() constructor and usage of the object:

var myWorker = new Worker("worker.js");

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