Time CountDown in angular 2
这是我的代码: import { Component,ElementRef,OnInit,OnDestroy } from '@angular/core'; import { Observable,Subscription,interval } from 'rxjs'; @Component({ selector: 'app-timer',templateUrl: './timer.component.html',styleUrls: ['./timer.component.css'] }) export class TimerComponent implements OnInit { private future: Date; private futureString: string; private diff: number; private $counter: Observable<number>; private subscription: Subscription; private message: string; constructor(elm: ElementRef) { this.futureString = elm.nativeElement.getAttribute('inputDate'); } dhms(t) { let days,hours,minutes,seconds; days = Math.floor(t / 86400); t -= days * 86400; hours = Math.floor(t / 3600) % 24; t -= hours * 3600; minutes = Math.floor(t / 60) % 60; t -= minutes * 60; seconds = t % 60; return [ days + 'd',hours + 'h',minutes + 'm',seconds + 's' ].join(' '); } ngOnInit() { this.future = new Date(this.futureString); this.$counter = Observable.interval(1000).map((x) => { this.diff = Math.floor((this.future.getTime() - new Date().getTime()) / 1000); return x; }); this.subscription = this.$counter .subscribe((x) => this.message = this.dhms(this.diff)); } } 收到以下错误:
我已尝试过在Google上可以找到的所有导入措施,但没有任何效果.我也更新到最新版本的rxjs,但仍然没有.任何帮助将不胜感激. 我相信我可能会遇到某种版本问题.真的很难过.
解决方法
只需写:
import { interval } from 'rxjs'; import { map } from 'rxjs/operators' interval(1000).pipe( map((x) => { /* your code here */ }) ); 在RxJS 6中,没有Observable.interval函数. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
