BroadcastChannel.name 是类型为 DOMString 的只读属性，是频道的唯一标识。属性 name 是在创建时传入 BroadcastChannel() 构造函数的，所以是只读的。
Note: 此特性在 Web Worker 中可用。
语法
var str = channel.name;
示例
// 连接到指定频道
var bc = new BroadcastChannel('test_channel');
// 其它操作 (如: postMessage, …)
// 在控制台打印频道名称
console.log(bc.name); // "test_channel"
// 当完成后，断开与频道的连接
bc.close();
