方法说明:
注册了指定event的所有监听器将被作为数组返回。
语法:
emitter.listeners(event)
接收参数:
event 指定事件
例子:
server.on('connection', function (stream) { console.log('someone connected!'); }); console.log(util.inspect(server.listeners('connection'))); // [ [Function] ]
源码:
EventEmitter.prototype.listeners = function(type) { var ret; if (!this._events || !this._events[type]) ret = []; else if (util.isFunction(this._events[type])) ret = [this._events[type]]; else ret = this._events[type].slice(); return ret; };
