Angular 角度5+;takeWhile不是一个函数
我有以下代码:Angular 角度5+;takeWhile不是一个函数,angular,Angular,我有以下代码: public ngOnInit(){ this.schemeStore.getSchemesByAffId() .takeWhile(() => this.isAlive) .subscribe((schemes: Scheme[]) => { const currId = schemes[0].currency; this.schemeFunds$ = this.fundStore .getSchemeValorization
public ngOnInit(){
this.schemeStore.getSchemesByAffId()
.takeWhile(() => this.isAlive)
.subscribe((schemes: Scheme[]) => {
const currId = schemes[0].currency;
this.schemeFunds$ = this.fundStore
.getSchemeValorizationsByCurrency(currId);
});
}
我甚至在导入takeWhile时使用了:
import { takeWhile } from 'rxjs/operators';
但我有一条错误信息:
ERROR TypeError: this.schemeStore.getSchemesByAffId(...).takeWhile is not a function
有人有想法吗?我猜导入错误,请尝试:
import 'rxjs/add/operator/takeWhile';
您正在使用rxjs6导入,因此需要将其与
管道一起使用
,否则将导入更改为导入'rxjs/add/operator/takeWhile'
谢谢,我错过了它。。。!
