  返回 boolean

destroyImp

• destroyImp(): void

  返回 void

disposableOn

• disposableOn(
      func: (...args: T) => void,
      scope?: Object,
      first?: boolean,
      handler?: EventListenerHandler<T>,
  ): () => void

  https://www.wolai.com/earthsdk/hwmaPRyLERtj1yyDCbBwbu#rjSrpzE5x8VYWLzGK62ebm

  参数

  • func: (...args: T) => void
  • 可选scope: Object
  • first: boolean = false
  • 可选handler: EventListenerHandler<T>

  返回 () => void

disposableOnce

• disposableOnce(
      func: (...args: T) => void,
      scope?: Object,
      first?: boolean,
      handler?: EventListenerHandler<T>,
  ): () => false | void

  https://www.wolai.com/earthsdk/hwmaPRyLERtj1yyDCbBwbu#bmn5iF21VQQ2Y44FyzsG4s

  参数

  • func: (...args: T) => void
  • 可选scope: Object

disposableWeakOn

• disposableWeakOn(
      func: (...args: T) => void,
      scope?: Object,

      handler?: EventListenerHandler<T>,
  ): () => void

  https://www.wolai.com/earthsdk/hwmaPRyLERtj1yyDCbBwbu#dP9hKQVbz6AkRVtDRPR41E 监听事件以后，当事件本身销毁时，会自动解绑事件， 除非确定event有可能提前销毁，否则尽量使用disposableOn，而不是disposableWeakOn 因为disposableOn使用后，如果没有及时销毁，控制台会给出事件有监听的警告！
