port 特性为 SharedWorker interface returns a MessagePort object used to communicate and control the shared worker.

句法

myWorker.port;
					

值

A MessagePort 对象。

范例

The following code snippet shows creation of a SharedWorker 对象使用 SharedWorker() constructor. Multiple scripts can then access the worker through a MessagePort object accessed using the SharedWorker.port property — the port is started using its start() 方法：

var myWorker = new SharedWorker('worker.js');
myWorker.port.start();
					

For a full example, see our Basic shared worker example ( run shared worker )。
