我想实现的功能是当用户有输入动作时开始计数，下次输入时离上次输出时间超过3秒停止计数并执行subscribe里的逻辑
Rx.Observable.fromEvent(input,"input") .startWith(0) .throttle(e=>Rx.Observable.interval(3000)) .subscribe(e=>console.log(e))
求问Rxjs中如何在不定义一个外部变量的情况下实现计数。
小伙看你根骨奇佳，潜力无限，来学PHP伐。
Rx.Observable.fromEvent(input, 'input').throttleTime(3000).scan(count => count + 1, 0).subscribe(count => console.log(${count}));
${count}
