Angular 5 ng2-loading-bar在firefox上无法正常工作

Question

我在我的项目中使用了@ ng2-loading-bar。

"devDependencies": {
    .
    .
    "ng2-loading-bar": "0.0.6",
    .
    .
}

它可以在Chrome上运行，但它无法在Firefox上正常运行。 Firefox中没有完成进度条。

import {LoadingBarService} from "ng2-loading-bar";

@Injectable()
export class HttpService {

    constructor(private http: Http,
                private loadingBarService: LoadingBarService,
                private logger: Logger,
                private storageService: StorageService,
                private tokenService: TokenService,
                private router: Router) {
    }

    private sendGet(url: string, headers: Headers): Observable<any> {
        headers.append("Content-Type", "application/json");
        headers.append("Accept", "application/json");
        let options = new RequestOptions({headers: headers});
        this.emitStart();

        return this.http.get(url, options)
            .map(this.onComplete)
            .catch((error: any) => this.handleError(error, this));
    }

    private emitStart() {
        this.loadingBarService.start();
    }
}

知道为什么装载栏不起作用？

Answer 1

它在Firefox浏览器中遇到ajax请求问题。但您可以简单地使用loadingBarService.complete()来完成加载栏。此功能已存在并在“ng2-loading-bar”包中定义。
