usage

EventTrigger

import { EventTrigger } from 'ray-event-tools';
// or import EventTrigger from 'ray-event-tools/lib/eventTrigger';

const et = new EventTrigger();

et.addEventListener('loaded', fn1, 0);
et.addEventListener('unloaded', fn2, 0);

// 触发 loaded
et.dispatchEvent({ type: 'loaded' });

/**
 * 添加事件监听
 * @param type 事件类型
 * @param listener 事件回调

RayEmitter

• 自定义创建

import { RayEmitter } from 'ray-event-tools';
// or import RayEmitter from 'ray-event-tools/lib/eventEmitter';

const emitterObj = {};
const emitterInstance = new RayEmitter(emitterObj);

// Listen on the given `event` with `fn`.
emitterInstance.on(event, fn);
emitterInstance.addEventListener(event, fn);

// Adds an `event` listener that will be invoked a single time then automatically removed.
emitterInstance.once(event, fn);

// Remove the given callback for `event` or all registered callbacks.
emitterInstance.off(event, fn);
emitterInstance.removeListener(event, fn);
emitterInstance.removeAllListeners(event, fn);
emitterInstance.removeEventListener(event, fn);

// Emit `event` with the given args.
emitterInstance.emit(event);
// Return array of callbacks for `event`.
emitterInstance.listeners(event);
// Check if this emitter has `event` handlers.
emitterInstance.hasListeners(event);

• 使用内置默认 instance

import { emitterInstance } from 'ray-event-tools';

...
