nodeEventTarget.addListener(type, listener[, options])

• type <string>

• listener <Function> | <EventListener>

• options <Object>

  • once <boolean>

• 返回: <EventTarget> 自身

EventTarget 类的 Node.js 特定扩展，可模拟等效的 EventEmitter API。 addListener() 和 addEventListener() 之间的唯一区别是 addListener() 将返回对 EventTarget 的引用。

• type <string>

• listener <Function> | <EventListener>

• options <Object>

  • once <boolean>

• Returns: <EventTarget> this

Node.js-specific extension to the EventTarget class that emulates the equivalent EventEmitter API. The only difference between addListener() and addEventListener() is that addListener() will return a reference to the EventTarget.
