node EventEmitter

[TomVista]

想在 event.emmit('eventName') 执行完异步事件之后 触发一个 end 事件,怎么做?

暴露 event 给 listener 吗?

const event = new (require('events').EventEmitter)
event.on('name',(event)=>{
	// dosomething
    setTimeout(()=>{
        ...
        event.emmit('nameEnd')
    },100)
    
})

event.on('nameEnd',()=>{
	console.log(name)
})

event.emmit('name',event)

const EventEmitter = require('events');

const event = new EventEmitter();

event.on('eventEnd', () => {
console.log('異步事件執行後觸發 eventEnd 事件');
});

event.on('eventAsync', function () {
setImmediate(() => {
console.log('異步事件觸發');
// to do...
this.emit('eventEnd');
});
});

event.emit('eventAsync');
