    addEventListener

    • addEventListener<K extends keyof WindowEventMap>(
          type: K,
          listener: (this: Window, ev: WindowEventMap[K]) => any,
          options?: boolean | AddEventListenerOptions,
      ): void

    • Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.

      The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.

      When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.

      When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.

      When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.

      If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.

      The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.

      Returns Window

    postMessage

    • postMessage(message: any, targetOrigin: string, transfer?: Transferable[]): void

    • Posts a message to the given window. Messages can be structured objects, e.g. nested objects and arrays, can contain JavaScript values (strings, numbers, Date objects, etc), and can contain certain data objects such as File Blob, FileList, and ArrayBuffer objects.

      Objects listed in the transfer member of options are transferred, not just cloned, meaning that they are no longer usable on the sending side.

      A target origin can be specified using the targetOrigin member of options. If not provided, it defaults to "/". This default restricts the message to same-origin targets only.

      If the origin of the target window doesn't match the given target origin, the message is discarded, to avoid information leakage. To send the message to the target regardless of origin, set the target origin to "*".

      Throws a "DataCloneError" DOMException if transfer array contains duplicate objects or if message could not be cloned.
