Методы

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

addEventListener( type: string, listener: EventListenerOrEventListenerObject, options?: boolean | AddEventListenerOptions, ): void

close(): void

Закрывает объект BroadcastChannel, позволяя его сборке мусора.

postMessage(message: any): void

Отправляет заданное сообщение другим объектам BroadcastChannel, настроенным для этого канала. Сообщения могут быть структурированными объектами, например, вложенными объектами и массивами.

removeEventListener<K extends keyof BroadcastChannelEventMap>( type: K, listener: (this: BroadcastChannel, ev: BroadcastChannelEventMap[K]) => any, options?: boolean | EventListenerOptions, ): void

removeEventListener( type: string, listener: EventListenerOrEventListenerObject, options?: boolean | EventListenerOptions, ): void
