如何在 rxjs 中取消订阅我漂亮的 TimerObservable
How to unsubscribe from my nifty TimerObservable in rxjs
我一直收到取消订阅不是函数的错误。我正在使用 rxjs@5.0.0-beta.12.
这些是我的导入语句:
import { TimerObservable } from 'rxjs/observable/TimerObservable';
import 'rxjs/add/operator/take';
这是有问题的 TimerObservable:
countdown = TimerObservable.create(0, 1000).take(6);
这将启动计时器:
startCountdownTimer(): void {
this.countdown.subscribe(
i => this.timeRemaining = (5 - i).toString(),
null,
() => this.toDelete = -1)
}
这,好吧,这行不通:
cancelCountdownTimer(): void {
this.countdown.unsubscribe();
}
subscribe
的来电者收到 subscription:
startCountdownTimer(): void {
this.subscription = this.countdown.subscribe(
i => this.timeRemaining = (5 - i).toString(),
null,
() => this.toDelete = -1);
}
它有一个 unsubscribe
方法:
cancelCountdownTimer(): void {
this.subscription.unsubscribe();
}
