class Worker extends EventTarget with AbstractWorker

The Worker interface represents a background task that can be easily created and can send messages back to their creators. Creating a worker is as simple as calling the Worker() constructor, specifying a script to be run in the worker thread.

Of note is the fact that workers may in turn spawn new workers as long as those workers are hosted within the same origin as the parent page. In addition, workers may use XMLHttpRequest for network I/O, with the exception that the responseXML and channel attributes on XMLHttpRequest always return null.

    The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on.

    The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).

    This implementation accepts a settings object of type EventListenerOptions.

    Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().

  20. val onerror: Function1[ErrorEvent, _]

    The AbstractWorker.onerror property represents an EventHandler, that is a function to be called when the error event occurs and bubbles through the Worker.

  21. var onmessage: Function1[MessageEvent, _]

    The Worker.onmessage property represents an EventHandler, that is a function to be called when the message event occurs.

    The Worker.onmessage property represents an EventHandler, that is a function to be called when the message event occurs. These events are of type MessageEvent and will be called when the worker calls its own postMessage() method: it is the way that a Worker has to give back information to the thread that created it.

  22. def postMessage(aMessage: Any, transferList: UndefOr[Array[Transferable]] = js.native): Unit

    The postMessage() method of the Worker interface sends a message to the worker's inner scope.

    The postMessage() method of the Worker interface sends a message to the worker's inner scope. This accepts a single parameter, which is the data to send to the worker. The data may be any value or JavaScript object handled by the structured clone algorithm, which includes cyclical references.

    The Worker can send back information to the thread that spawned it using the DedicatedWorkerGlobalScope.postMessage method.

    MDN

    aMessage

    The object to deliver to the worker; this will be in the data field in the event delivered to the DedicatedWorkerGlobalScope.onmessage handler. This may be any value or JavaScript object handled by the structured clone algorithm, which includes cyclical references.

    transferList

    An optional array of Transferable objects to transfer ownership of. If the ownership of an object is transferred, it becomes unusable (neutered) in the context it was sent from and it becomes available only to the main thread it was sent to. Only MessagePort and ArrayBuffer objects can be transferred. null is not an acceptable value for the transferList.
