| 方法 | 类型 | 介绍 |
|---|
| on | (target: EventEmitterTarget, cb: EventEmitterCallback)=>EventEmitter | 监听 target 触发 cb |
| once | (target: EventEmitterTarget, cb: EventEmitterCallback)=>EventEmitter | 监听 target 触发一次 cb |
| emit | (target: EventEmitterTarget, ...params:unknown[])=>void | 触发 target |
| off | (target?: EventEmitterTarget, cb?: EventEmitterCallback)=>EventEmitter | 取消 target |
EventEmitter.all
- 所有 target
eventEmit.emit(target)，执行回调
const eventEmit = new EventEmitter.all(target:EventEmitterStaticTarget, cb: EventEmitterCallback)

EventEmitter.any
- 任何一个 target
eventEmit.emit(target)，执行回调
