Experimental: 这是一个实验中的功能
此功能某些浏览器尚在开发中,请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订,所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

The active property of the ServiceWorkerRegistration interface returns a service worker whose ServiceWorker.state is activating or activated. This property is initially set to null.

An active worker controls a ServiceWorkerClient (en-US) if the client's URL falls within the scope of the registration (the scope option set when ServiceWorkerContainer.register is first called.)

Note: This feature is available in Web Workers.
